Abstract—OpenFlow is a unique concept to realize softwaredefined networking (SDN). It realizes the network flexibility by separating control plane and data plane. Data plane is implemented by OpenFlow switch. We discuss how to implement OpenFlow switch on FPGA (Field-programmable gate array). FPGA implementations of the OpenFlow switch have been researched. But their architectures are for only 5-tuple fields or OpenFlow1.0. OpenFlow is dramatically updated in short time, so we should design new architecture for newer OpenFlow specification. In this study, we propose how to implement the packet classification for OpenFlow1.3 switch on FPGA. Our idea is to use packet classification algorithm which contains a strideBV algorithm and a range bit vector encoding algorithm. We apply them to 13 fields which are required in implementations.
