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.

ETSI NFV ISG Chair Steven Wright recognized Tetsuya Nakamura, NFV ISG Vice Chair for outstanding contributions in NFV Phase 1

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.

New leadership, renewed charter, and an enhanced structure to facilitate the transition from requirements to implementation

Marc Cohn, Market Development, Ciena Corporation – Santa Clara, CA  USA

Wandering through the Computer History Museum in Mountain View, at the social gathering of the ETSI Network Functions Virtualisation Industry Specification Group (ETSI NFV ISG), was like a trip down memory lane. International Business Machines (IBM) mainframes (e.g., 360/370, which I spent many a night working on at the University of Missouri in the 1970s), Digital Equipment Corporation (DEC) minicomputers (I was a systems manager for the PDP-11 and VAX-11/780 at McDonnell Douglas in the 1980s), and a slew of computers, calculators, and gadgets whose manufacturers have faded from memory.

But in an austere exhibit rests the system that truly changed the world- the IBM PC. Aside from its size, price point, and design, what made the PC different was IBM’s decision to open up the platform, decoupling the software from hardware, publishing open specifications, fostering the greatest ecosystem the world has ever known.

Three decades later, networking and telecommunications are bracing for a major transformation as communications platforms prepare to be opened by Software Defined Networking and Network Functions Virtualization, with similar impact to the opening of the computing world.

The 7th meeting of the ETSI NFV ISG was co-hosted by Ericsson and Citrix in the Santa Clara Convention Center, whose warm hospitality, comfortable surroundings, and ideal weather made for a highly successful meeting. Attendance surged to over 300 people; not surprisingly the 3 highest attended NFV meetings were held in Silicon Valley (NFV #4 (355), NFV #7 (303), and NFV #2 (285)).

Over the past year-and-a-half, the ISG has grown beyond the capability of all but the largest corporate facilities:

  • 37 operators spanning the globe (up 4 since NFV #6 held in May)
  • Mailing list approaching 1,200 participants
  •  226 ISG members (up 18 since NFV #6)
  • 23 Proof of Concepts (PoCs) accepted (up 5 since NFV #6)
  • 15 active work items

NFV #7 marked the last meeting for the Chair (Prodip Sen (HP)) and Vice Chair (Uwe Michel (Deutsche Telekom)), who played a major role in the ISG’s growth and success to date.

Throughout NFV #7, the ISG focused on repositioning the organization for long-term success, an initiative loosely referred to as NFV Phase 2. Among the key outcomes:

  • Elected new leadership, as the current Chair and Vice-Chair stepped down
  • Facilitated the transition from the Requirements Phase to the Implementation Phase
  • Revisited the ISG operational structure in anticipation of the transition
  • Discussed high-level scope for 2015 and beyond

Open elections were held for the NFV ISG Chairman and Vice-Chairman, who recently stepped down from their posts at the previous meeting in May.

Outgoing Chairman Prodip Sen commented, “Serving as a founding member and the first chair of the NFV ISG has been an extremely rewarding experience. We started out to create momentum in the industry, and provide guidance on the way forward to the vision. We have achieved these goals, but clearly much still needs to be done. The good thing is that with this global team we have created, there is no dearth of ideas and participation. I am fully confident that the new leadership will continue our positive trajectory towards long-term success. ”

Outgoing Vice-Chair Uwe Michel stated “When we started the NFV ISG back in 2012, we did not envision such rapid growth and enthusiastic validation. I feel fortunate to be able to work with such a strong leadership team, who are truly committed to achieving an industry vision for NFV.”

Steven Wright, AT&T, who formerly led the NFV Infrastructure (INF) working group, was elected the new NFV ISG chairman. “I am excited to guide the NFV ISG as we transition our focus from requirements to implementations. I would also like to thank Prodip Sen and Uwe Michel for their leadership and significant contributions, which have been instrumental to our success.”

Tetsuya Nakamura, NTT DOCOMO, who formerly was the Assistant Technical Manager of the NFV Technical Steering Committee (TSC) and Chair of the Software Architecture (SWA) working group, was elected the new NFV ISG Vice-Chair. “I am honored to be elected vice chair of the NFV ISG at such a critical time, as the ISG repositions itself to focus on adoption.  We are especially appreciative of my predecessor Uwe Michel, who has been a major part of our success from the beginning. ”

The ISG continues to make solid progress on the NFV Release 1 baseline. Eleven new deliverables from multiple working groups were made available for public reviews. A liaison statement was approved to invite comments from the many NFV ISG liaisons.

“I continue to be pleased with our progress towards NFV release 1, which is targeted towards December”, stated Diego Lopez (Telefonica), NFV Technical Manager and Chair of the NFV Technical Steering Committee. “Each of our technical working groups is making tremendous progress as we worked towards a solid technical baseline, which is critical as NFV Phase 2 gets underway.”

Another major topic discussed at NFV #7 was the future of NFV ISG, referred to as ‘NFV Phase 2’. The original charter for the ISG, approved in late 2012, is scheduled to expire in January, 2014. Prodip Sen led a robust evening discussion on the future of NFV, assisted by Klaus Martiny, Vice-Chair, Network Operator Council (NOC) and incoming Steven Wright.

Key outcomes from NFV #7 regarding NFV Phase 2:

  • The ISG passed a motion to extend the NFV charter by 2 years, to continue to operate under the current ETSI Terms of Reference (ToR)
  • The ISG accepted a new NFV ISG mission statement, which shared the vision, mission, and values of the NFV ISG:
    The NFV ISG’s mission is to facilitate the industry transformation and development of an open, interoperable, ecosystem through specification, implementation and deployment experience. . .
  • Several new contributions on NFV Phase 2 were submitted for consideration, many endorsed by multiple participants
  • The ISG leadership will hold an interim meeting in late September to discuss the proposals and suggestions for NFV Phase 2, in preparation for NFV #8 in mid-November

“Interoperability is a key objective for Network Operators”, commented Don Clarke (CableLabs), Chair of the NFV NOC. “In the next phase we intend to intensify our efforts towards achieving interoperability for NFV, which includes normative work where appropriate, formalized dialogue with other industry and standards organizations including open source communities, and a continued emphasis on encouraging open NFV implementations and Proof of Concepts.”

At the closing plenary, the new ISG leadership invited the NFV ISG plenary to proactively contribute to the future of NFV, through comment on our documents, proposals for new work items, and recommendations on the organizational structure to position the NFV ISG for long-term success.

While progress since the formation of the ISG (4Q2012) has been tremendous, there is a long way to go. The ISG will be shifting their focus outward, reaching out to the standards bodies, industry groups, and open source projects, to influence their future work programs. A proposal was shared to stimulate discussion on how the NFV ISG can engage with the research community, to leverage their innovations, resources, and ongoing work as well as to create new academic courses to train a new generation of students to be multi-skilled in networks and software. In today’s environment, collaboration is the norm, implementations the target, and speed trumps completeness.

The next meeting of the ETSI NFV ISG (NFV #8) will be held from Nov 17-21 in Chandler, AZ (outside of Phoenix). At that time, the new leadership will assume their responsibilities, and decisions are anticipated on the plan for NFV Phase 2.

In this exclusive interview, Mavenir’s Ian Maclean shares his insights on SDN and NFV.

We are hearing a lot of discussion about Software Defined Networks (SDN) and NetwoMavenirrk Functions Virtualization. In the wireless space, how do you see operators benefiting from NFV or SDN?

IM: “The industry debate isn’t about which one provides the most benefits. It’s more about which one is the logical first step for operators. We think that’s NFV. It enables operators to start reaping the benefits of virtualization today instead of waiting for a payoff that may be three or more years down the road.

“Familiarity is one major reason why NFV is the ideal first step. The virtualized network functions are simply software instantiations of existing core network elements onto virtualized platforms. Suppose that an operator already has an Evolved Packet Core (EPC) and an IP Multimedia Subsystem (IMS) core. All of those nodes – Packet Gateways, Session Border Controllers (SBCs), Telephony Application Servers (TASs) and so on – all become virtualized network functions. But the logical interfaces between them remain the same, as does the management interface.

“As a result, although NFV is fundamentally different from traditional, hardware-centric networks, it still looks very familiar to mobile operators. That translates to a shallow learning curve. By comparison, SDN radically changes the network topology. So although SDN simplifies the network, which is a big plus, it does it in a way that requires operators to think and act differently. That takes time, which means the payoff takes time.”

How does Mavenir see virtualization changing how mobile operators will transform their networks to 4G LTE?

IM: “Mobile operators eventually will implement Voice over LTE (VoLTE). Some are doing it earlier than others for business reasons. For example, operators with legacy CDMA networks can use VoLTE to eliminate the expense and complexity of maintaining that fallback in the network and devices.

“One way to do VoLTE is to have several hardware to provide nodes such as the Session Border Controller (SBC), the Telephony Application Server (TAS), and so on. The virtualization way is to instantiate each of those nodes into a virtual machine that consists of one or two physical cores of a CPU on a blade.

“Mavenir has taken the latter approach, which enables us to quickly and easily implement services with nodes on a single blade. Our solution is an example of how virtualization reduces CapEx and OpEx.

“The IMS core is another example of where the CapEx and OpEx benefits are realized. A half chassis with as few as four to eight blades can provide an entry-level IMS network of, say, 100,000 subscribers. Without virtualization, you’re looking at several racks of hardware.”

With the implementation of virtualization technology, what new services do you see leading the way in telecommunications?

IM: “NFV still has a ways to go before it’s mature, but VoLTE is already generating a lot of interest for the reasons I mentioned. Increasingly, that interest is evolving into deployments. Some U.S. operators have launched VoLTE already, and Verizon Wireless says it will launch VoLTE later in 2014.

“Another reason for the interest in VoLTE is that despite its name, it also lays the foundation for operators to offer a wide variety of video and messaging services, including ones that compete with over-the-top (OTT) service offerings.

“VoLTE also is an ideal way for mobile operators to provide voice service to tablets, which many enterprises see as a replacement for desk phones and PCs. So VoLTE helps mobile operators push deeper into the enterprise and displace more wireline.”

How does technology such as virtualization change the offerings that operators will provide in the future?

IM: “Virtualization reduces the cost and complexity of networks, which reduces risk. That means operators can test more offerings when it comes to developing and implementing services. Some of those will be successful with customers, giving those operators more revenue and new opportunities to attract and retain subscribers.

“Virtualization also minimizes time to market and time to revenue. Mobile operators have traditionally taken a year or more to develop a service and implement it in the network. During that window, they’re vulnerable to rivals such as OTT players and other mobile operators. Virtualization enables operators to implement those services via software, so they can get to market much faster: potentially months or quarters rather than a year or longer.

“Finally, virtualization also enables new opportunities to maximize service quality, such as quicker call setups and HD Voice. Some customers, such as enterprises, will pay a premium for high-quality service, especially if they want mobile to replace some or all of their wireline services.”

What do carriers need to do to get started in taking advantage of this next generation technology?

IM: “The first step is to decide which parts of the network they want to virtualize first. Many of the operators Mavenir works with, are starting with the Evolved Packet Core, while others are starting with the IMS core. That’s another benefit of our virtualized solutions, operators can move at their own pace and virtualize whatever meets their business objectives.”

How is Mavenir helping mobile operators take advantage of these networking trends?

IM: “We have over 9 years of experience, substantial investment in wireless technology, and are engaged with tier one operators globally. Our unique experience of transforming mobile networks for the delivery internet protocol (IP)-based voice, video, rich communications and enhanced messaging services using virtualization, IMS and VoLTE enables mobile operators to transform their networks seamlessly and painlessly. We launched the world’s first VoLTE and world’s first RCS with MetroPCS, so we have the expertise and knowledge to move forward.

“We have a comprehensive suite of virtualized solutions, built on the mOne® software platform that enables operators to develop innovative, reliable services and get them to market quickly and cost-effectively. We have a suite of functions in the network that are IMS- and EPC-based, and designed for operators to deploy on their own in-cloud infrastructure today in a virtualized model. And when they’re ready to build out an NFV framework, Mavenir’s mOne® is designed to support that model, too.”

Welcome to the latest newsletter from SDN World News, guiding you through the latest developments in the world of Network Functions Virtualization and Software-Defined Networking. We are pleased to bring together the best of the resources we’ve been watching in recent weeks, so you can keep in touch with SDN and NFV the easy way.

The industry gathered in London two weeks ago for Network Virtualization & SDN World, a unique, global, operator-led conference and exhibition, now in its second year, focusing on all aspects of SDN and NFV with particular relevance to the telco community.

This year’s event featured a great deal of focus on SDN and NFV deployment strategies across the network, with thought-provoking contributions from many prominent industry leaders including BT, NTT, Comcast, Telstra and Telefonica, and a host of NFV Proof of Concept demonstrations from leading vendors in the accompanying exhibition.

The Software-Defined Data Centre Summit which opened the event also offered valuable new insights into this expanding new area from Deutsche Telekom, Colt, Pacnet, Telus and JT Global, while the API Forum which concluded the conference brought together NTT, PCCW Global, BT, OpenDaylight and the OpenStack Foundation and high-profile vendors for a rewarding debate on openness and collaboration and developing a common approach towards Telco APIs.

The Network Virtualization Industry Awards were also well-received, with wins for Nuage Networks, Cyan, Colt, RAD and Tail-f. Click here for the full results:

Packed conference rooms throughout the event also paid witness to the fact that the NFV industry buzzword is far from diminishing – and as the ETSI NFV ISG prepares to move towards a brand new era in 2015 and beyond, the future is looking particularly bright.
