Universal node: Towards a high-performance NFV environment

Available in English Español (Latinoamérica) Português
Software-Defined Networking (SDN) and Network Function Virtualization (NFV) both promise the vision of more flexible and manageable networks, but they also require certain level of programmability in the data plane.

Current industry insight holds that programmable processors (both CPUs and NPUs) are of lower performance than their hard-coded counterparts, such as Ethernet chips.

In this paper we show that Open Flow (OF) can be used for implementing various network functions, such as routing, and the performance we can get can match the non-OF implementations of the given network function once some bottlenecks are removed. Our prototype can do 100 Gbps (gigabit per second) even with small packets on one Intel blade, reaching a noticeable 110 Mpps packet speed with 64 byte long packets.
