NFV offers operators a dual benefit of decreased OPEX and increased opportunity for profitable service creation and introduction.
Much of the attention in NFV has been focussed on the benefits to be gained by virtualising functions in the control plane. Understandably so, given that these are CPU-intensive functions that offer up good potential benefits of virtualisation. But this focus has to date ignored the challenges and opportunities for NFV in the data plane, which has very different requirements in terms of capacity and throughput to the control plane.
This eBook argues that it is possible to design platforms to support data plane functions in the drive to NFV – to the benefit of all.
