Interview with Ampai Pornprasertsakul, Deputy Director, True Corporation, Thailand

Ampai PornprasertsakulIn advance of Network Virtualization & SDN World in London on 27-30 May 2014, we caught up with Ampai Pornprasertsakul, Deputy Director at True Corporation in Thailand, to find out more about her perspective on SDN and NFV in 2014.

Ampai, welcome. What are your impressions of SDN and NFV in telecom networks to date?
AP: “Telecom operations are still in the process of exploring the SDN and NFV capability and impact. The realization is it is coming, and that we shall all need to prepare for it.”

What do you think are the biggest hurdles towards implementing SDN and NFV at present, and how can they be overcome?
AP: “The biggest hurdles that remain are how best to implement SDN and NFV, how to determine the biggest benefits we can get from them, working out how this new technology will impact our existing network, and what exactly the implementation costs will be.  We also need to know how best to integrate SDN with network equipment, VAS and IT systems.”

Which areas of the network do you think should be prioritised for virtualization, and why?
AP: “Personally, I think that VAS (Value Added Services) should be prioritised first for virtualization. The reasons for this are the high feasibility of implementation in this area, and that VAS has less impact on key services. I believe that less mission-critical services should be tested first.”

What are your expectations for the development of SDN and virtualization in telco networks in coming years?
AP: “In coming years, I foresee that SDN and Virtualization will continue towards full network implementation. Eventually, I anticipate the integration of network, VAS and IT systems as one.”

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.”

Peter Zidar 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.

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.
