Better ARP handling with InSPired SDN switches
Fabian Schneider, Roberto Bifulco, Anton Matsiuk · 2016
SDN research is moving towards enabling the delegation of parts of control functions to the network elements. In recent work we analytically evaluated the benefit in terms of ARP data traffic load reduction as well as control channel interaction reduction when delegating the generation of ARP replies. In this paper we describe the corresponding control program and network configuration to handle ARP traffic in a software-defined network leveraging programmable in-switch packet generation capabilities. We also discuss potential optimizations and implementation options.
