Just like the transition of Enterprise IT systems to Cloud Computing, so the trend towards Network Virtualisation and programmable networks is heating up and unstoppable.
Industry Momentum Building Fast
Judging by the attendee numbers at this year’s SDN & OpenFlow World Congress, in Düsseldorf last month, the industry momentum is building up fast. Apart from doubling the prior year’s attendee numbers (and that in a part of Europe that certainly does not feature among its major Tourist destinations), this third world congress on Software Defined Networks (SDN) featured a large vendor exhibition, including most of the established major networking, applications and software vendors, as well as many start-ups in these areas. It also featured an extensive display of Network Function Virtualisation (NFV) Proof of Concept (POC) demos.
Network Function Virtualisation was a major theme in this multi-streamed SDN World Congress. It may be fair to say that the industry momentum towards NFV is even stronger than that for SDN. Judging for instance by the over 220 member companies of the ETSI NFV Industry Specification Group (ISG) Initiative with well over 30 operator members represented. (Compared to the about 150 members of the Open Networking Foundation – ONF).
The applications of NFV are certainly much easier understood and the value of cloud computing with its scalability and bursting capability and clear economic advantages are well known and attractive to operators. Many major operators are involved in the program of ETSI NFV approved public POC demos that cover a wide range of use cases for telecom operators.
SDN as Enabler for NFV in Networks
NFV does not require SDN, but the ETSI NFV group has from the start made a case that NFV and SDN are perfect complements. At the SDN World Congress in Düsseldorf the outgoing ETSI NFV chair, Prodip Sen, presented an interesting analysis that clearly showed that for telecom networks which are by nature geographically distributed and need to provide built-in reliability and diversity, SDN is an essential complement to NFV. Of course SDN is also a key technology to implement service chaining or Virtual Network Function (VNF) Forwarding Graphs (FG), which is a vital enabler for the richness of personalized virtualized function offerings that service providers may want to offer in order to tap into the rich incremental revenue potential opened up by the NFV technology.
Key Focus Areas: Openness, Performance, Real-time Orchestration
The key focus points of industry discussion around NFV are the need for truly open NFV implementations, to verify and ensure performance for NFV network applications, and to move from monolithic traditional OSS architectures to more cloud oriented real-time NFV Orchestration platforms, in order to fulfill the vision for NFV and to reap its full potential.
The Importance of Openness
The recently founded Open Platform for NFV (OPNFV) initiative, led by Margaret Chiosi, which is focused on realizing this vision for open NFV, was well represented and sharing its industry vision towards open NFV. NTT DoCoMo made a significant announcement about successful multi-vendor NFV testing for virtualized mobile core, where various multi-vendor combinations of the NFV architecture building blocks were successfully tested. This is an important step towards achieving open NFV. NTT DoCoMo also announced its intention to move towards deployment of NFV technology in the coming year.
Cultural Change and Skills Training Needs
So the momentum towards Network Virtualisation and Programmable Networks, ie NFV and SDN, is building. Some operators have already started these deployments, eg the European operator Colt. They note the need for cultural change in their organisations and the breaking down of silos in order to see the successful introduction of these new technologies. And related to this is the looming need for skills training and certification in SDN and NFV, as was highlighted by Dan Pitt, the Executive Director of the Open Networking Foundation (ONF), who is in the process of developing an SDN certification program to launch in 2015.

There are a few major shifts or points of inflection in the history of ICT and telecommunications networks. The clear message coming from major players at the Broadband World Forum is that the coming move towards programmable networks, ie SDN and NFV is such a point of Inflection leading to major network and industry shifts.

At the annual Broadband World Forum (BBWF) in Amsterdam, where the global Telecom Technology Executives meet, NFV and Network Virtualisation are in the Limelight. This year BBWF hosts a number of live NFV POC demos. Blue Ocean Networks contributed to a panel session on "Tackling Deployment Challenges for NFV"
Though NFV has been launched just two years ago, in October 2012, by a small band of 13 global Tier 1 operators, it has made significant strides. The ETSI NFV group that was formed in response to the Call to Action in October 2012, now has over 220 members and over 30 operator members. The initial set of requirements, architecture and framework specifications will be completed by January 2015. Over 25 multi-vendor and operator sponsored POCs are in progress or have been completed.
In Phase 2 of the ETSI NFV initiative, starting at the end of January 2015, the key focus will be on Interoperability and achieving Openness. The recently launched OPNFV Open Source NFV initiative has a similar key focus on Openness.

Key NFV Take-Away Points from the SDN & OpenFlow World Congress 2014 in Düsseldorf were:
- Openness is essential for successful NFV. Openness means there can not be a vendor lock-in
- Performance and carrier grade SLAs are vital. This is evidenced by the large number of ETSI POCs. Many are testing out use cases and performance points. Performance in a carrier NFV deployment is different to Cloud. NFV is not just another Cloud Data Centre, it means in-line processing at the speed of packets and with minimal delay etc to deliver services in real time.
- The need for a shift in OSS from the legacy monolithic systems to a real-time dynamic orchestration approach, as is being outlined in the NFV MANO approach.

Software Defined Networks (SDN) and Network Function Virtualisation (NFV) are about to re-energise the telco market space and create a ‘Blue Ocean’ business environment and huge opportunities for service providers not seen since the start of the explosive growth of the Internet.
These are some of the conclusions highlighted at the recent Software Telco Congress – the SDN & NFV event in Las Vegas. http://tinyurl.com/qbb3rk8
“…carriers can grow their revenue by providing virtualized-services to their enterprise customers by placing solutions in the customer’s cloud. By providing virtualized customer equipment, carriers will be able to cost-effectively compete with OTT cloud-communications vendors more effectively.”
Asked “‘What is the opportunity’”, ”‘Massive – huge – incredible – I haven’t seen an opportunity in the telco ecosystem space this big since 1998’”
So are Telcos really doomed to suffer a “dumb pipe” slow death? The tables are turning thanks to SDN and NFV …
Blue Ocean Networks is running a number of Workshops on Software Defined Networking and Network Function Virtualisation which analyse the business drivers, the business opportunities and use cases for telecom service providers and enterprise networks and the key technologies to deliver SDN and NFV networks

Virtual home gateway capability based on SDN and NFV provides the broadband subscriber with greater control and a potentially vast new range of services by being able to directly link into network based cloud services.

According to Infonetics Research the cumulative value of the Telecom and Datacom equipment and software market over 5 years to 2018 will exceed USD 1 Trillion. Half the total spend will be with the five largest vendors: Cisco, Huawei, Ericsson, Alcatel-Lucent and ZTE. (source: Infonetics Research)
The global telecom and datacom equipment and software market reached USD 183 Million in 2013 and will continue to grow steadily with the industry move towards SDN and NFV technologies.
While the growth in telecom and datacom equipment and software spend is about a cumulative 20% over the five years, the growth in telecom traffic is forecast to be much more substantial, with a threefold growth in global Internet traffic forecast over this time period, and much higher growth rates forecast for both the mobile network traffic and the cloud data center traffic.
The move to the new SDN and NFV technologies is seen as a major factor in more efficiently scaling networks in a cloud-like virtualisation approach to networks and thereby stabilising the telecom Capex spend in the face of rapid traffic growth.
