Telcos Turn Spotlight on Virtualization
Why this matters
There is a lot of discussion, and excitement, about how the virtualization of networking functions and the use of SDN protocols such as OpenFlow might make it easier and cheaper to manage telecom networks. (See Drop the Fruitcake: It's SDN Time and 2012 Belonged to SDN & NFV. But Will They Deliver in 2013?) Consequently, the major network operators need to figure out just what might really be possible and what the cost and efficiency implications might be. The implementation of virtualization techniques could herald a new wave of networking that might reinvigorate some operators and provide a platform for extended viability. Equally, it could create a networking nightmare that could hasten some operators' demise. The NFV group has a tough task -- needing to remain sober in the face of an intoxicating proposal for industry suppliers while, at the same time, not sitting on their hands for years just discussing the issues. The industry at large can help by holding back from making outlandish claims about the potential for NFV and SDN. That, though, might be a bit too much to ask. — Ray Le Maistre, International Managing Editor, Light Reading
