Network functions virtualization (NFV) and Software Defined Networking (SDN) will get a lot of interest this year at BBWF 2014 Broadband World Forum 2014 as carriers seek to make networks more agile and efficient. In talking to both service providers and large enterprises, it’s clear that we are already in another major transition in the networking industry.
I’ve spoken with many talented individuals about what NFV and SDN means to their networks. Some of these visions are very broad and long ranging and some are more narrowly focused on delivering or optimizing a single service very quickly. It’s clear that NFV has already been deployed in many different service applications while SDN has been noticeably slower to develop a focused following. Even in the case of Virtualized Network Functions (VNFs), there is an interesting combination of features focused on services delivery and features focused on infrastructure innovation. In this case “services” are typically the services that carriers sell to their end customers such as a Virtual Private Network (VPN) and “infrastructure” is the virtualization of the typical network functions such as a virtualized route reflector on an x86 based server instead of running the route reflector application in an existing (physical) router.
