I don’t think anyone would dispute software is the new currency in networks.
The Network Functions Virtualization (NFV) initiative calls for defining and deploying the next generation of network functions with software, rather than specialized hardware. Software Defined Networking (SDN) is another visible trend which although currently focused on data centers, is predicted to impact networking markets broadly in the future.
Network Functions Virtualization (NFV) is getting a lot of attention in Telecom circles these days. Initiated by leading providers around the world the NFV effort now has more than 150 participants crossing all of the functional boundaries in networking. NFV has been motivated by the astonishing array of appliances that have crept into provider networks. Even DNS appliances have emerged but the value proposition is almost exclusively around convenience rather than optimizing DNS for carrier environments.
