Does SDN Need a Faster Version of TCP/IP?

The transport layer of the protocol stack has direct implications for use of software defined networking, many would argue, and therefore creates a need for SDN-optimized versions of TCP/IP.

So it is that the new OpenFastPath  Foundation, founded by Nokia Networks, ARM and industrial IT services player Enea, seeks to create an open source TCP/IP stack which can accelerate the move towards SDN in carrier and enterprise networks.

AMD, Cavium, Freescale, Hewlett Packard Enterprise and Linaro also are supporting the effort to create a standardized, accelerated TCP/IP stack that provides top performance for SDN-ready network functions.

For network operators, the new fast-path stack should lead to reduced IP latency, higher capacity and thus faster packet forwarding, and lower implementation costs.
