NFV Phase 2 begins: new leadership, organization, and renewed focus on implementation

By Marc Cohn, Ciena Corporation

While much of the country was coping with sub-freezing temperatures, the ETSI Network Functions Virtualization Industry Specification Group (NFV ISG) convened its 8th and final meeting under its original charter in the desert sunshine in Scottsdale. Intel graciously hosted the meeting, arranging excellent accommodations and hospitality throughout the week.

NFV #8 was the first U.S. NFV ISG meeting held outside of Silicon Valley, with no drop off in interest:

  • Number of operators: 37
  • Total number of organizations: 245
  • Number of individuals on the mailing list: > 1,200

After taking the industry by storm (literally)- attendees will never forget the unexpected and rare snowfall in the Cote d’Azur at the very first meeting of the ISG (February, 2013)- NFV Phase 1 successfully concluded, with the ISG achieving its stated objectives and defined work program. In recognition, parties sprung up by most working groups to celebrate their success.

“Operator participants are extremely pleased with the outcomes of NFV Phase 1”, stated Don Clarke (CableLabs), Chair of the Network Operator’s Council. “Few of us could have anticipated how fast this initiative would grow and how influential it would become. As we enter Phase 2, operators’ expectations continue to rise. We are very conscious of the fact that vendors are investing significant resources to develop NFV capability. It is therefore very important to stay focused and maintain our momentum to create opportunities for NFV deployment.”

NFV operators have every right to be proud, as NFV has literally redefined the ground rules for telecommunications technology adoption by:

  • Avoiding the temptation to create new standards- the ISG instead worked to influence existing and emerging SDOs and open source projects
  • Highly collaborative engagement model:
    o Among operators, some of whom are fierce competitors
    o Between operators and vendors
  • Reinventing itself as needed to adapt to the challenges at hand
  • Adopting a pragmatic approach that emphasizes progress over completeness and implementations over technical elegance
  • Capitalizing on a familiar and well-established administrative model that permitted the ISG to concentrate on progress vs. process

ETSI Director General Luis Jorge Romero commented “We are pleased that ETSI could enable the groundbreaking NFV ISG, which successfully forged an innovative standardization cooperation model, built upon assertive goals, pragmatism, lightweight process, and unprecedented collaboration. We applaud the ISG’s phenomenal accomplishments to date and believe that the NFV ISG is already influencing the entire industry.”

After months of planning, guided by the incoming ISG leadership elected at the prior meeting in July, the NFV Phase 2 work program commenced with a general agreement on the objectives and work scope:

  • Grow an interoperable VNF Ecosystem
  • Thoroughly specify reference points and requirements defined in Phase 1
  • Achieve broader industry engagement to ensure that NFV requirements are satisfied
  • Clarify how NFV intersects with SDN and related standards, industry, and open source initiatives

Steven Wright (AT&T), presiding over his first meeting since being elected Chair of the ETSI NFV ISG observed “I remain encouraged by the elevated enthusiasm by operators and partners alike. The NFV community that we have fostered has never been more robust. While we have challenges to overcome, broad industry participation has resulted in a healthy debate on our Phase 2 plans, which are converging as expected.”

In Phase 2, the ISG agreed to disband the existing NFV ISG Working Groups, and approved a new leaner working group structure better suited to the goals for Phase 2. While a healthy debate unfolded regarding the detailed Phase 2 scope and working group inter-relationships, a general consensus emerged, and the work began immediately.

The new working groups will focus less on requirements and more on adoption. Among the key areas that will be addressed include:

  • The ‘ilities’: Stability, Interoperability, Reliability, Availability, Maintainability
  • Intensified collaboration with other bodies
  • Testing and validation to encourage interoperability and solidify implementations
  • Establishment of a vibrant NFV ecosystem
  • Performance and assurance considerations
  • Continued attention to network management and operations, which is of particular interest to
    the Network Operators Council
  • Security

The ISG also elected new technical leaders to guide the NFV technical agenda. Diego Lopez (Telefonica) was re-elected as the Technical Manager, and Joan Triay (DOCOMO) was elected Assistant Technical Manager, succeeding Tetsuya Nakamura (DOCOMO), who was recently elected Vice-Chair of the NFV ISG. Working group leadership will be elected at the next plenary meeting (NFV #9), scheduled for Prague in late February.

“I am pleased that the ISG reiterated their confidence in me as we approach NFV Phase 2”, commented Diego Lopez, Technical Manager for the ISG. “As our goals shift towards implementation and adoption, we will need more detailed specifications, and address functional gaps of the standards we adopt. In order to achieve our goals, it is critical that our working groups remain focused, operate with lightweight processes, and strive for interoperability in everything that we do.”

As the ISG made a seamless transition, with a renewed charter, new leadership, and updated working group structure, the ISG has been energized to pave the way to adoption. Two years of use case assessment and prioritization, requirements analysis, architecture definition, document alignment, and countless conference calls, meetings, and drafts have resulted in a solid baseline for Phase 2.

Tetsuya Nakamura, ETSI NFV ISG Vice-Chair, stated “I am thrilled about the progress we made on the technical baseline in Phase 1, which required a great deal of collaboration and effort. Congratulations to all contributors for their commitment, dedication, and hard work without which, the leap to Phase 2 would not be possible.” Fittingly, Tetsuya, along with Michael Brenner (Alcatel Lucent), Joan Triay (DOCOMO), and Frank Zdarsky (NEC) were recognized by the ISG leadership with a special award for their outstanding contributions to Phase 1.

Given the accomplishments in Phase 1, there is increasing optimism that the ETSI NFV ISG will achieve its lofty goal to radically transform the entire telecommunications industry. 2015 is shaping up to be the year of the trial, leveraging over 25 Proof of Concepts, visible strides in product development, and leading edge operators planning for initial deployments.

Interview: Phil Braden, PCCW Global

Phil will be speaking at Carrier Network Virtualization 2014 on Wednesday, December 10 at Crowne Plaza Palo Alto. Click here to download the full agenda.

 
What would you say has had the largest impact in terms of progressing SDN and NFV in carrier networks to date?
I would say that AT&T’s “Domain 2.0” announcement had a very significant impact on the progress of SDN and NFV in carrier networks as it has signaled that the big telco players are seriously seeking innovative approaches to network management and operation. That being said – the actual developments in SDN still lag behind and attempt to implement a Data-Centre solution on a Carrier network, which obviously operates in a different environment. Now it is time for SDN to seek an innovative approach and adapt the earlier, Data-Center centric, models to innovative models that match the Carrier environments. NFV, on the other hand, is progressing nicely and is already implemented in certain parts of the network.

 
Do you feel that the industry is making as much progress towards implementing SDN & NFV this year as you would like?
SDN adoption lags behind in the carrier networks due to its inapplicability to the Carrier network environment. Now it is time for SDN to seek an innovative approach and adapt the earlier, Data-Center centric, models to innovative models that match the Carrier environments: Long latency, Lack of diversity, High cost of transmission, High port-density, Reliability. NFV, on the other hand, is progressing nicely and is already implemented in certain parts of the network.

 
How is your company contributing to the realisation of SDN & NFV at present?
PCCW Global is an active participant in several industry SDOs such as MEF, ONF, ETSI-NFV. Through our participation we voice the need to make SDN more carrier-friendly, more agnostic to protocols and more process orientated. We trust standardized APIs are key to allow SDN to evolve from a Data-Centre application into Network-Programmability framework.

 
What do you think are the biggest hurdles towards implementing SDN & NFV at present and how can they be overcome?
SDN, at present, is still focused on device management, debating OpenFlow vs. NetConf/YANG and others. With a strong drive from white-label HW manufacturers. This model does not address the needs of Carrier networks. Not because it is a bad model, but because it is based on assumptions that were good for the environment where SDN and NFV were conceived: The Data-Centre. In the DC distances (and latency) are short, bandwidth cost is negligible, diversity is easy to implement and resiliency is obtained through stocks of failover devices readily available.

Carrier Networks operate in an entirely different environment where distances are vast, latency is high, diversity is difficult (and expensive) to establish, bandwidth is a significant element of cost, port-densities are very high and device resiliency is a key factor. Thus – carriers tend to stick with their incumbent hardware suppliers that provide devices that have proven track records of survivability, built in resiliency, high port densities and RISC processors that are designed for the sole purpose of pushing packets and frames from one port to another.

SDN must evolve from a Device/Controller paradigm into a Platform/Controller paradigm, and must become agnostic to the SouthBound interface through which the Controller interfaces with the Platform – Be that OpenFlow or NetConf or YANG or others. This will also require an evolution from managing single devices, one by one, towards managing an entire platform or an entire network. The SDN model will need to evolve from the initial three-plane model (Application-Control-Data) into a multi-plane model that includes parts of the device-OS (provided by the HW manufacturer), an Abstraction layer (that represents the vendors-specific hardware and transport resources as abstracted and vendor agnostic resources), a resource catalogue layer (that represents the network resources to higher layers) a Virtualization layer (that assembles network resources into virtual service instances) and a controller that is closer to being an OSS than the current SDN controllers in the market.

NFV is actually progressing nicely. Its applicability in a carrier network is limited because Carrier network gear typically revolves around switching and pushing packets from one port to another. Storage, Applications and processing (other than packet forwarding) are absent from the core of the carrier network. On the edge of the network, however, and at the customer premises, NFV already plays a nice role: Smart CPEs on one side (acting as a mix of router/firewall/VoIP switch) and CPE-elimination on the other side (migrating the functionality of the CPE to a VNF on the Provider-Edge).

 
Which areas of the network do you think should be prioritised and why?
Our pain-point is Network-Programmability, and that is where we want to see progress. NFV on the CPE is in the right direction and we would want to see more applications there, hopefully standardized.

 
What are your expectations for the development of SDN and Virtualization in carrier networks in the coming years?
The industry, as a whole, is shifting its efforts towards automation. Managing networks manually is getting out of hand, and new applications and the growth in use of mobile data create a need for on-demand managed services. SDN and NFV are the primary enablers of network automation as they allow configuration and activation of services through software rather than through manual processes. We expect to see SDN evolve to become orchestrated, application aware, Situation-aware, agnostic to SB interface type and capable of interfacing with neighbour controllers for the realization of multi-platform services. This requires shift in efforts of the SDOs from writing code (be that open-source or proprietary) towards defining information models and specifying APIs. It then becomes the role of the hardware and software vendors to adapt their systems to the standardized information models and create APIs per specs.

Which companies do you most admire in the SDN space?
PCCW Global has identified tail-f as an important player that can bridge legacy and innovative platforms. We were not surprised to see it being acquired by a major player, and we think the HW vendors that have initiated a software line of products (e.g. Cisco with tail-f and their own home-grown projects, ALU with Nuage, Ericsson with Telcordia) are worth looking at, as the SDN space as we know it will need to shift closer to the OSS, and the OSS will need to interface closely with the network gear. In addition to that I will also watch companies developing orchestration solutions, especially those who offer expertise in process analysis and information modeling, as they may become critical elements in the migration of carriers from traditional, legacy, network environments towards programmability.

What would you say has had the largest impact in terms of progressing SDN and NFV in carrier networks to date?

Industry Collaboration between Operators, Standards bodies and Vendors. Open Platform NFV has the greatest potential, provided everyone plays nice between incumbents & whitebox suppliers.

Do you feel that the industry is making as much progress towards implementing SDN & NFV this year as you would like?

Early case studies in the industry are promising, but these tend to be simpler given the risk with any new technologies. There could always be more progress, but being a realist the pace of progress is about what I expected.

How is your company contributing to the realisation of SDN & NFV at present?

POCs from past year are moving to trial. New POCs are being assessed. Industry events participation is also an important contribution.

What do you think are the biggest hurdles towards implementing SDN & NFV at present and how can they be overcome?

Operational Model for the new World order the embraces NFV & SDN. Furthermore, clarity of use cases and the realization of their direct benefits to the Operator.

Which areas of the network do you think should be prioritised and why?

Data Centres are a fertile ground for initial use cases because projected growth warrants a more scalable approach than business-as-usual.

What are your expectations for the development of SDN and Virtualization in carrier networks in the coming years?

More successful early deployments will help increase confidence of fast followers. Standard solutions that are modular & easy to replicate will be winners.

Which companies do you most admire in the SDN space?

Ones that are Innovative and Open in the spirit of putting their Customers First.

Interview with Hrvoje Jerkovic, Service Quality Assurance Manager, Vipnet, Croatia

Hrvoje JerkovicIn advance of Network Virtualization & SDN World in London on 27-30 May 2014, we caught up with Hrvoje Jerkovic, Service Quality Assurance Manager, Vipnet, Croatia to find out his thoughts on the industry in 2014.

Welcome Hrvoje. What would you say has had the largest impact in terms of progressing SDN and NFV in telecom networks to date?
HJ: “In last few months we have seen real flood of announcements regarding NFV implementations. Some of them refer to Proof of Concepts, and some to implementations in real live networks. It is obvious that this is more than just upgrades to technology, and operators are very careful with this topic.
“Generally, the main reason lies in the opportunity to cut hardware costs by reusing the same COTS hardware platforms for different telco appliances. Through better utilization of hardware and through using distributed software block-architecture of NFV based telco elements, operators have the opportunity to make significant cost savings as well as optimization of resource usage.”
Do you feel that the industry is making as much progress towards implementing SDN and NFV this year as you would like?
HJ: “NFV presents a major shift in telco architecture. Such changes need time to develop to reach functionality and telco-grade stability of legacy architecture; therefore, I would answer yes. We have to accept the fact that no operator wants to gamble with their core business, even if the potential savings might be big. This is the reason for taking small steps and virtualizing only certain network functionalities on certain technologies.”

What do you think are the biggest hurdles towards implementing SDN and NFV at present, and how can they be overcome?
HJ: “In terms of hurdles, the main technical reason is non-maturity of current NFV based products. As mentioned earlier, many operators are making small steps, just because they don’t have full confidence to make bigger steps. Beside that, there is also a constant need for each operator to adapt the set-up of its processes driven by NFV architecture.”

Which areas of the network do you think should be prioritised for virtualization, and why?
HJ: “In the first phase, we should focus on network elements covering signaling and control functions. Some of them might be IMS related , VoLTE related, policy functionalities, messaging services, Gi services etc. After that, data plane nodes which have clearly specific and/or different requirements could follow in the second stage.”

What are your expectations for the development of SDN and virtualization in telco networks in coming years?
HJ: “Based on initial experience, SDN and virtualization’s footprint is likely to spread in certain steps, depending on operators’ plans to extend in this direction. The logical way forward for operators is to exchange legacy equipment when NFV-based solutions can fulfil functionality/stability requirements and old legacy equipment reaches an end-of-life state.”

 Which company do you most admire in the SDN / NFV space, and why?
HJ: “It would be impolite to pick any vendor right now. The interesting thing is that, beside traditional ICT vendors (also known as the big players), we see many small agile vendors on the market trying to position themselves in the mix as well. Both of these have weakness and strengths, and I think it’s good for industry and good for the market as well to see some new players.”

Interview with Peter Zidar, Head of Standardisation Group, Telekom Slovenije

Peter ZidarIn advance of Network Virtualization & SDN World in London on 27-30 May 2014, we caught up with Peter Zidar, Head of the Standardisation Group at Telekom Slovenije, to find out his thoughts on SDN and NFV in 2014…

What would you say has had the largest impact in terms of progressing SDN and NFV in telecom networks to date?

PZ: “The largest impact is coming from implementations of cloud computing, Cloud RAN and M2M. At the core of cloud technologies are virtualization mechanisms. It is also important for network operators to reduce cost by avoiding proprietary hardware implementations and virtualizing network services. They can reduce CAPEX (by using of the shelf equipment) and OPEX (by running network functions in the data centre) by implementing SDN and NFV. Operators want to migrate from self-contained routers to a centrally-controlled distributed environment to simplify maintenance. Advantages of SDN and NFV can increase velocity of deploying new upgrades.”

Do you feel that the industry is making as much progress towards implementing SDN and NFV this year as you would like?

PZ: “Progress is still a bit slow but gaining momentum. Implementing SDN and NFV was at first slowed down by lack of proper standardization. With an increasing number of cloud services offered by network operators as well as upgrades to the C-RAN, these two technologies will make big step forward to become more widespread. It takes some time for network operators to be assured that the security, resilience and availability of their networks are not impaired when virtualised network functions and SDN are introduced.”

How is your company contributing to the realisation of SDN and NFV at present?

PZ: “We have implemented some SDN functions in our core network and are planning to participate at different EU projects, which are going to use those functions in conjunction with IoT and video routing. We are already preparing our networks for greater use of SDN and NFV.”

What do you think are the biggest hurdles towards implementing SDN and NFV at present, and how can they be overcome?

PZ: “The biggest hurdles are legacy networks and multivendor environments. Also, more SDN and NFV capable products should be available. One of the reasons for slow deployment is the lack of ability to load and execute virtual appliances in different but standardised datacentre environments, provided by different vendors for different operators. Virtualization is causing some performance degradation, so it may not always be optimal, and some operators may therefore hesitate to implement it. Another hurdle is the necessary co-existence with legacy network elements and compatibility issues.”

Which areas of the network do you think should be prioritised for virtualization, and why?

PZ: “All new network elements should be prioritized for virtualization to appropriately scale and upgrade mobile networks in future. All cloud services, including C-RAN, are also obvious places to start with virtualization.”

What are your expectations for the development of SDN and virtualization in telco networks in coming years?

PZ: “I expect that network operators will first try to use SDN and virtualization to implement and deploy cloud services, and then use it also for Cloud RAN. The use of these technologies may very likely transform the vendor landscape. Each player will need to re-position itself in new markets. Vendors will offer virtualized versions of their products, and network operators will have to migrate their operations and skill base to a software based networking environment.”

Interview with Shahar Steiff, AVP Business Operations, PCCW Global

Shahar SteiffIn advance of Network Virtualization & SDN World in London on 27-30 May 2014, we caught up with Shahar Steiff, AVP of Business Operations, PCCW Global, to find out his thoughts on the industry in 2014…

Shahar, welcome. What would you say has had the largest impact in terms of progressing SDN and NFV in telecom networks to date?

SS: “If we have to take one event this year that made the largest impact on the future of SDN and NFV, I would say it is AT&T’s publishing its “Domain 2.0 Vision”. When one of the world’s largest carriers announces its support of SDN and NFV technologies, it provides the whole industry assurance that their efforts are spent in the right direction. And using AT&T’s own words: “Domain 2.0 is not a completed architecture or technology plan; rather it sets direction. There remains much to do…”

2) Do you feel that the industry is making as much progress towards implementing SDN and NFV this year as you would like?

SS: “The industry is still in “hype” mode when it comes to SDN and NFV. Several limited test cases have been proven to work, but the business case is still unclear. In addition to that, the majority of the work and progress is limited to the “comfort zone” of the data-centre, where SDN and NFV were conceived, while developments related to carrier networks and mobile networks are still at infancy.”

How is your company contributing to the realisation of SDN and NFV at present?

SS: “PCCW Global is a contributing member at several of the Industry Standard-Defining-Organizations, such as MEF, ONF, 3GPP.

“At PCCW Global we believe that the industry as a whole will benefit from convergence towards standardized APIs that will allow vendor agnostic abstraction and virtualization.”

What do you think are the biggest hurdles towards implementing SDN and NFV at present, and how can they be overcome?

SS: “Implementation of SDN and NFV is effected by three factors:

a. The technology is still maturing and has limited commercially available solutions.

b. The technology is optimized for data-centre environments and needs to be further enhanced to suit the specific needs of carrier’s transport networks.

c. Integration of SDN and legacy equipment is still under development. A migration plan that retains the value of previous investments needs to be developed.

“In addition to that, today’s “selling point” for SDN and NFV is “Cost-Savings”, while the business case for that approach still needs to be proven. Instead, I trust that once carriers start realizing the operational benefits of this technology and the NEW REVENUE opportunities it may bring, they will be more keen to give it a try.”

Which areas of the network do you think should be prioritised for virtualization, and why?

SS: “To date – SDN and NFV have been realized in the Data-Centre. That’s one part of the network. There are other parts of the network that need to undergo the same: Wireline/Wireless/Mobile access networks, the packet core network, aggregation layers.

“The key is agnostic abstraction, which should be implemented on any of the above mentioned network areas. Agnostic abstraction which defines the service regardless of the vendor, the carrier and the underlying technology. Once that is achieved, virtualization becomes simple to implement. This emphasizes the key role of SDOs (Standard-Defining-Organizations) in the future of SDN and NFV. It is only through collaboration of vendors, service providers and OSS/BSS platform developers that the industry will be able to define consensus-based abstracted services and APIs that the vendors and OSS/BSS developers will then be able to implement in their hardware and software, allowing the carriers to virtualize their services in a ubiquitous manner across the different areas.”

What are your expectations for the development of SDN and virtualization in telco networks in coming years?

“To date – SDN and NFV development has focussed primarily on the Southbound-Interface. That’s a good starting point. There’s much debate going around the Northbound interface at this time. However – taking into account that in today’s environment services will almost always transit beyond the boundaries of one operator/system/carrier/platform into one (or more) other platform(s), it is key that an Eastbound-API is developed. Such Eastbound-API will allow a service to span across multiple domains delivering end-to-end management.

“As an example: A mobile user establishing HD Video conference with two other users: another mobile user that is subscribed to another mobile operator, and a colleague in the main office sitting at their desk. In the future SDN/NFV managed network, a VPN with CoS characteristics and bandwidth that is capable to convey an HD video signal will be established, in real time, from each user’s device, through their access network (mobile or wireline), through the core backbone of their network provider, to the MCU (Media Concentration Unit) in “the cloud” (a data-centre somewhere).

“For this example scenario to properly function – all elements of the network must use the same service abstractions and same APIs, regardless of their make, model or software release. A “guaranteed 768Kbps from device A to device B” is the same no matter if one device is a mobile phone on an LTE network and the other device is a macbookpro connected to the office WiFi. If all platforms along the path support the same standards, SDN and NFV will allow real-time delivery of billable CoS-managed-network services.”

Shahar will be speaking in more detail about his thoughts and ideas at Network Virtualization & SDN World in London on 27-30 May 2014. For further information and to register for the event, please visit www.sdnworldevent.com.

Where Will These Top Carrier SDN Vendors Be One Year From Now?

Last August, Craig Matsumoto of Light Reading posted his listing of the Top 10 Carrier SDN Vendors, admitting “Picking a ‘Top 10’ in software-defined networking (SDN) is a dangerous business, because the whole sector is in flux.” Six months later, how are those ten (actually 11, with OpenDaylight) picks faring?

1. OpenDaylight. Although not an independent vendor, OpenDaylight opens the list because it is a “community-led, open, industry-supported framework, for accelerating adoption, fostering new innovation, reducing risk and creating a more transparent approach to Software-Defined Networking…OpenDaylight is structured using open source development best practices, and is comprised of the leading organizations in the technology industry.”

When OpenDaylight started, it only had two open-source projects. Now, it has sixteen. Thanks to OpenDaylight software-defined networking, rivals and users are being brought together by open source and creating software-defined networking for everyone.

2. VMware/Nicira. A little over a year after the Nicira acquisition, VMware announced its network virtualization platform called NSX whose goal is to enable users to deploy a virtual network for an application at the same speed and operational efficiency as a virtual machine. In addition, VMware announced multiple program enhancements at the VMware Partner Exchange 2014. So it’s safe to say that VMware is still in the game.

3. Juniper/Contrail. Despite one story reporting trouble with the introduction of Contrail to Juniper’s engineering team earlier this year, Juniper continues to position itself to introduce the new approach needed for management, provisioning and maintenance of connections as companies push infrastructure to “hyperscale levels” in anticipation of Big Data, mobile traffic and advanced sync/sharing services. Juniper marketing director Steve Shaw said, “With physical networks simply incapable of handling such a dynamic load, enterprises will find that SDN is necessary, regardless of the long-term ROI.” And Juniper intends to be a part of that.

4. ConteXtream.  In addition to joining the OpenDaylight project, the company collaborated with Cisco Systems to contribute a LISP-based mapping service to the open source SDN project OpenDaylight that enables the federation of SDN controllers across a WAN. Obviously, ConteXtream is still a player.

5. Big Switch Networks. Early on, Big Switch Networks dropped out of its leadership position in the OpenDaylight Project due to, among other things, concerns with Cisco over whose technology would form the foundation of an OpenDaylight SDN controller. Now Big Switch Network reports that it is ready to embark on a new chapter after rebooting its business late last summer.

6. Cyan. Cyan recently announced that its Blue Planet SDN Platform and Z-Series packet-optical hardware have been selected by the Jeollanam-Do province in South Korea. This will be deployed together with partner Telefield with the new network delivering e-government applications in support of the two million citizens living in the province.

7. Alcatel-Lucent/Nuage. In January,  Nuage Networks announced that UPMC selected its software-defined networking platform for deployment in their backup network. Once the staging and verification are deemed successful, UPMC will begin a multi-year transition to Nuage Networks solutions for the rest of its datacenter network infrastructure to support the increased demand from employees, patients, hospitals, and healthcare insurers.

8. Cisco/Insieme. Cisco Systems has been consistently labeled as a late adopter of SDN, but between its “spin-in” with Insieme Networks, unveiling its Application-Centric Infrastructure last November and now the investment of $6 million in Embrane, Cisco is positioning itself for the leadership position once more.

9. Plexxi. Plexxi is still in the news, and has contributed to articles and information for OpenDaylight, but there doesn’t seem to be anything new in the way of product changes or launches.

10. Ciena. Ciena is a Silver-level member of the OpenDaylight Project and active contributor to the OpenDaylight code base. In addition, Ciena reports that it is working closely with their customers to understand the widespread implications of SDN on their existing and future networks. According to a recent interview, one of Ciena’s SDN experts Marc Cohn said, “Parts of our SDN portfolio, such as our V-WAN, are already shipping, and many of our customers have expressed interest in the OpenDaylight framework. As a result Ciena has been closely investigating the potential application of the OpenDaylight framework for future products. Ciena has not yet announced our SDN product plans in this area, but we expect to soon.”

11. Brocade/Vyatta. The Stargate Group, an Australian application service provider (ASP) to the mortgage finance sector, announced on February 12 that it “has taken its first step toward applying software-defined networking (SDN) to its operations with the deployment of Brocade® NetIron® CER 2000 Ethernet/MPLS routers.” And earlier in February, Brocade today introduced the rollout of an enhanced channel program, including a new component specifically designed for software networking partners.

January 2014 bulletin

HappynewyearHappy new year to all our followers!

The main SDN and NFV buzzwords for 2014? We predict: Simplicity, Capability, Speed, Openness and (most importantly) Value For Money!

It’s certainly a bright new year in many ways, in which we are likely to see a whole raft of new virtualization ideas and deployments coming through.

There has been much discussion surrounding SDN and NFV developments in the last few weeks. At the Carrier Network Virtualization conference and exhibition in Palo Alto on 9-11 December, valuable discussion ensued around the future pathway of network virtualization, now that so many possibilities are emerging. A very popular White Box panel asked, can you now tell the difference between a White Box switch by an ODM and one bought from a large traditional vendor? In terms of performance, it is argued that it is very often no longer possible. However, in terms of support around the product, many still prefer the aftercare attention and extra resources provided by established vendors. Yet as the ODMs begin to increase in size and scope, a similar level of aftercare might one day also be available from them. Several new players asserted in discussion that moving away from the established vendors would make way for much more creativity in terms of how technology is used… Only time will tell as to how many operators make that jump.

2014 also marks the final year of the ETSI NFV ISG project in its current form. They have already achieved a great deal, but now the focus will be on drawing their work towards a conclusion which will help to shape the future of the industry. Definitely one to watch…

Meanwhile, the four-day Network Virtualization & SDN World event take places across four days in London on 27-30 May 2014, featuring an API Forum, SDN Summit, many SDN and NFV case studies and over 60 speakers.

Interview with Francisco-Javier Ramón Salguero, Telefónica

Francisco Javier Ramon SalgueroIn advance of Carrier Network Virtualization, taking place on 9-11 December 2013 in Palo Alto, California, we caught up with Francisco-Javier Ramón Salguero, Head of Network Virtualization, Telefonica GCTO, Spain, and Chair of the PER Expert Group, ETSI NFV ISG, to find out his thoughts on the growth of SDN and NFV and Telefonica’s plans for the future….

Francisco-Javier, welcome. What are you most looking forward to about Informa’s Carrier Network Virtualization event? 

FJRS: “This event is an excellent opportunity to share views with Industry and with other telcos and to know their first experiences and key progresses.”

Why is the idea of SDN and NFV suddenly taking off now? Why all the fuss?

FJRS: “The need for building a “future-proof network”, built to support a long-term strategic vision and flexible enough to allow for changing requirements, is a common wish for Telco operators.

“The digital world requires both flexibility and agility, and SDN and NFV hold the potential to transform telco networks substantially in this way for the better. This is the reason why the idea of SDN and NFV are being so popular today. Both of them are ideas that telcos have been waiting for a long time.”

Whereabouts in telco networks do you see that SDN and NFV will be of the greatest benefit? Where will we see the first deployments?”

FJRS: “The application of network virtualization can address two fronts. On the one hand, matching with other industry players in those environments where virtualization technologies are already part of the state of the art. Two examples are using SDN technology in telco data centers and using network functions virtualization in those functions intensively associated with the control plane. Network functions that could be first virtualized are those most associated with network intelligence and service platforms (eg IMS, SDP, DNS, UDB, etc.), as they are essentially datacenter-like workloads in our current networks.

“On the other hand, Telco Industry can act as a leader, using virtualization technologies to develop use cases on favourable terms from our competitors. This requires the ability to virtualise network functions that can deal also with the data plane, which is one of our peculiarities (in the end of the day, operator’s business is often based in transporting information). These network features are those normally associated with the IP Edge and the point of presence in general (BRAS, GGSN , SBC , P-GW , etc).”

Are there still any major hurdles you see which SDN and NFV have to conquer before adoption can become widespread? If so, what are they and how should they be resolved?

FJRS: “One of the major challenges of Network Virtualisation (SDN + NFV) is precisely to free the network of the rigidity imposed by physical infrastructure. To achieve this, the idea through NFV is to define a common layer of general-purpose hardware which is ready to support network functions completely defined by software.

“Once a network functionality can be completely defined by software, it is possible to use virtualisation technologies for packaging each network function in one or more virtual machines and decide in which server deploy them.

“However, as simple as it sounds, it is far from being a trivial process. Not everything looks alike to the traditional cloud computing. Allocation of hardware resources for a virtual machine needs to be more careful to assure a high and predictable performance. The challenge of this innovation is just this, to be able to maintain the performance when network functions are purely software. Currently, a number of advances in general-purpose hardware have increased by an order of magnitude the performance, so this is something feasible but still needs to be matured.”

What kind of timescale are we looking at until SDN and NFV become more commonplace in carrier networks across the world?

FJRS: “Only a few companies have commercial products which allow conceive specific parts of the network using these technologies. Almost all the equipment manufacturers are still at testing phases, announcing that NFV products will be launched soon.

“As it stands at the moment, SDN is already something real, implemented and deployed in the world of the major OTTs (like Google), while the Telcos are some way behind. Meanwhile, NFV developments, which arrived on the scene more recently, are still in a pre-commercial phase, with the first rollouts expected sometime 2014.

“Another challenge is that the operators already have a huge number of traditional nodes deployed which are will not be replaced by “commoditised” hardware overnight. That is why consideration is being given to hybrid models, which virtualise some network elements and incorporate the advantages of SDN to improve management. All this transformation is a process that will take years.”

What are your own company’s plans for deploying SDN and NFV?

FJRS: “At this moment, we are working in a trial in Brazil to virtualise part of the equipment installed at customer premises (router, cable TV decoder, etc.), in a concept that we call vCPE (virtualised Customer Premises Equipment). This trial is the result of a prototype developed by Telefónica I+D, with contributions and integration by NEC. The solution makes possible that higher layers functions can be shifted from the client premises to the operator’s network.

“We expect this pilot experience will help us prove the viability of this technology and enable us to implement rollouts in a more flexible and reliable way, obtaining low operating costs.”

What do you expect will be the defining trends within the industry in 2014?

FJRS: “There are numerous experiences being carried out both in the SDN field and in NFV in European, Asian and North American operators. However, it is still unclear when these operators will feel ready to deploy them massively in their network and what are the kind of investments they will need to make. What is clear is the need to work together in the industry (telcos and manufacturers) to define the specific requirements of the networks to ensure that these technologies provide the adequate maturity to support commercial rollouts.

“Manufacturers and telcos alike agree on the need to have a network which is much more flexible and mouldable, and which can be controlled as a whole. Major rollouts are expected to begin in 2015 and 2016, although it is very likely that the first rollouts will be seen sometime in 2014.”

Francisco-Javier will be speaking more about Telefonica’s plans for SDN and NFV on Wednesday morning as part of Carrier Network Virtualization in Palo Alto, California, 9-11 December 2013.

Speaker Interview: Ravinder Shergill, Senior Technology Architect, Telus, Canada

Ravinder ShergillWith Carrier Network Virtualization just around the corner, we caught up with another of the show’s speakers, Ravinder Shergill, Senior Technology Architect from Telus, Canada. Here are a few of his thoughts on the nature and growth of the NFV and SDN industries in 2013/4: 

RS: “We’re living during exciting times, with the opportunity to effect technological innovations for years, and perhaps decades to come.

“With incredible data growth and significance of cloudification, business as usual will not suffice. New and innovative models must be explored, and SDN and NFV hold the promise of such potential. First solution sets are targeted at the Data Center environment, and the greatest opportunity lies there. However, the opportunities landscape is much broader.

“The SDN and NFV eco-system is currently in transition, but as the roadmaps and the standards solidify, it will pave the way for easier acceptance

“Small adoptions, perhaps as pilots, are imminent, but broad deployments are further away, perhaps even 5 years out. As the SDN and NFV eco-system develops, this will pave the way for gaining traction in the industry. While there has been good progress in 2013, there is a long journey ahead.

“At Telus, we are now at the Proof-of-Concept stage, and the outcomes of these will determine our future plans.”
