Interview with Haim Geron, Senior Deputy Director-General, Israel Ministry of Communications

çééí âéøåï - ñîðë"ì áîùøã äú÷ùåøúIn advance of Network Virtualization & SDN World in London on 27-30 May 2014, we caught up with Haim Geron, Senior Deputy Director-General, Israel Ministry of Communications, to find out his thoughts on progress within the industry in 2014…

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

HG: “I believe that the recognition by major manufacturers like Cisco, HP and Juniper, major Software co. like VMware and announcements by application giants like Facebook about the development of Open Source based applications contributed to the rapid progressing of SDN and NFV to date.”

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

HG: “Telecommunications experts always feel that the progress towards implementation is NOT what they would like and again and again get “disappointed that it takes roughly 10 years from concept to mainstream implementation. However, we see some positive signs that the adoption of SDN/NFV architecture my “break” the 10-year barrier.”

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

HG: “As a regulator, we favor any technical advance that may reduce cost for operators and eventually, some of the cost savings will be transferred to consumers.”

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

HG: “I believe that the current, huge ‘sunk cost’ of legacy networks imposes the biggest obstacle to the rapid implementation of SDN/NFV. One way of overcoming that is to lower the entry-level barrier for new service providers who did not yet make a significant CAPEX in legacy networks. Another way is to devise sophisticated acquisition plans for SDN/NFV systems so that the CAPEX+OPEX of these new systems will be less than the long-term OPEX of the installed legacy systems.”

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

HG: “Obviously the Core Network will be prioritized because that’s where the applications get prioritized. In the access network, be it mobile or fixed, ‘a bit is a bit’.”

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

HG: “Reducing cost for the benefit of consumers, flexibility in the development of new services and a fair and proper implementation of Net Neutrality principle.”

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 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.

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.
