Abstract

OpenFlow switching enables flexible management of enterprise network switches and experiments on regular network traffic. We present in this paper a complementary design to OpenFlow's existing reference designs. We apply network processor based acceleration cards to perform OpenFlow switching. We describe the design options and report our experiment results that show a 20% reduction on packet delay and the comparable packet forwarding throughput compared to conventional designs.
