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.”

Hrvoje Jerkovic will be speaking in more detail about his thoughts and ideas on SDN and NFV 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.

Interview with Renu Navale, Senior Strategy Manager, Communications & Storage Infrastructure Group, Intel

Renu NavaleIn the build-up to Informa’s Network Virtualization & SDN World conference in London on 27-30 May 2014, we caught up with Renu Navale, Senior Strategy Manager, Communications & Storage Infrastructure Group at Intel, to find out her thoughts on the latest developments within the industry.

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

RN: Four tectonic shifts are fuelling a transformation in networking:

First, cloud has become the compute paradigm: Cloud has opened up new business models where compute can be purchased and provisioned on demand anywhere on the globe. This compute-on-demand model increases pressure on the network to keep up – to the point where networking is becoming a bottleneck and CapEX and OpEx models aren’t sustainable.

Next, there’s the emergence of Open Standards for Networking: The rise of software-defined networking has spawned a number of open standards that pave the way for an open ecosystem for networking solutions. Key examples include OpenFlow, Open vSwitch, and OpenStack.

Network Virtualization on the Rise: Server and storage virtualization have been around for years, allowing workload consolidation or pooling and provisioning of resources without regard for their physical locations. Now virtualization has extended to networking. Network virtualization allows IT to combine different physical networks into a single virtual network, or split a physical network into multiple virtual networks that are isolated from each other.

And finally, Moore’s Law Expands to Networking: Through the evolution of Moore’s Law and Intel library software optimization, Intel Architecture-based systems are now able to perform networking workloads on commercial off the shelf servers that once required ASICs and FPGAs utilized in dedicated proprietary appliances.

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

RN: The rate of industry engagement in NFV is fantastic, with over 200 companies now signed up to the ETSI NFV initiative in record timescales.  During 2014, we anticipate a downturn in publicity in line with the Gartner “Hype Cycle”, but there’s actually massive progress behind the scenes.

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

RN: Intel is leading the acceleration to an Open Network Transformation by enabling the delivery of “Best in Class” SDN & NFV solutions through:

  • Creation of reference platforms via the Development & Integration of Intel building blocks (we are introducing a portfolio of associated hardware and software products
  • Contributions to Standards, Open Source and Open interfaces (we are active in several SDN and NFV PoC and Standards initiatives across the ETSI, ONF, DMTF, and ODCA communities)
  • Collaborations & industry partnerships

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

RN: The key challenges are proving the operational scalability of SDN & NFV to carrier levels, and the consolidation of IT and Network operations to handle the rate of service evolution demanded by the market.  We are handling these by engaging in trials with several operators who are progressively expanding the scale of projects and associated risk mitigation. It is critical for the technology and business practices to complement each other to enable an operationally sound roll out of SDN/NFV. Other challenges are rollout of standards, vendor lock-in, and inter-operability challenges. An open and collaborative environment is critical to overcome this hurdle.

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

RN: We see virtualised Enterprise CPE as a great stepping stone for operators wanting to get started with production services, where the network speeds and the business risk are relatively low and the operations staff can get experience with an integrated IT and Network service approach. The “Services LAN” in both Fixed and Mobile Broadband networks looks like another key location to provide rapid service differentiation, intelligent handling of growing video traffic demands, and handle ever-increasing security challenges from Internet based threats.

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

RN: We expect virtualisation of Telco networks to be widespread, with the introduction of NFV infrastructure in Access, Regional and Centralised network nodes, enabling “right placement” of applications to suit operational requirements. The adoption of SDN could be slower, as (unlike the datacentre case) centralised management of carrier infrastructure has been available for many years.        

Which company do you most admire in the SDN / NFV space, and why?

RN: I think Intel’s approach to SDN and NFV is exemplary, based on the unflinching commitment to Open standards and enabling an entire market for the common good.

One company other than Intel would be AT&T…I think their Supplier Domain 2.0 initiative, coupled with their AT&T Foundry investments to lower the barrier to innovation – and their support of both large and small companies (Ericsson, Tail-f, Affirmed, Metaswitch, etc…) – is very disruptive and market-leading.

Network Virtualization & SDN World takes place in London on 27-30 May 2014. Renu will be delivering Intel’s key messages in a prominent keynote presentation at on the morning of Thursday 29th May. To find out more and to sign up for the event, please visit www.sdnworldevent.com.

April 2014 bulletin

Welcome to the latest newsletter from SDN World News, guiding you through the latest developments in the world of Software-Defined Networking and Network Functions Virtualization.

There continues to be lots of movement in the market, with vendors constantly bringing out announcements of new NFV and SDN solutions – 2014 is certainly a year for great innovation! One of the announcements which has attracted a great deal of interest this month is Cisco’s new open protocol for SDN, OpFlex. Devised as an alternative to OpenFlow, it is already a popular standard among SDN vendors, with Citrix, Microsoft, IBM, Canonical, RedHat, Embrane and F5 all now collaborating and supporting the standard. Cisco plans to use OpFlex for its own Application Centric Infrastructure, forging a bold, strong path through the competitive landscape surrounding SDN and NFV this year.

Meanwhile, in its commitment to Network Virtualization, AT&T has recently expanded its Domain 2.0 group, with Amdocs and Juniper becoming the latest vendors to join the group, alongside existing members Ericsson, Tail-F Systems and MetaSwitch. Domain 2.0 has been devised as a discussion group surrounding the design and deployment of AT&T’s User-Defined Network Cloud, and is intended to help improve time-to-revenue, provide cost-performance leadership, enable new growth services and apps, ensure security, performance and reliability and facilitate new business and revenue models.

Also, the four-day Network Virtualization & SDN World conference is set to take place across four days in London on 27-30 May 2014, featuring an API Forum, SDDC Summit, SDN and NFV case studies by 50+ operators and including a comprehensive exhibition alongside the event. Operators can attend free of charge by registering here: http://sdnworldevent.com/free-pass-registration/.

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. The brochure is due to be launched in 2-3 weeks’ time.  To find out more and to apply to take part, please visit www.sdnworldevent.com or contact Owen.Lochner@informa.com for information on sponsorship and exhibiting.
