Abstract

SDN has become the wide area network technology, which the academic and industry most concerned about.The limited table sizes of today's SDN switches has turned to the most prominent short planks in the network design implementation. TCAM based flow table can provide an excellent matching performance while it really costs much. Even the flow table overflow cannot be prevented by a fixed-capacity flow table. In this paper, we design FTS(Flow Table Sharing) mechanism that can improve the performance disaster caused by overflow. We demonstrate that FTS reduces both control messages quantity and RTT time by two orders of magnitude compared to current state-of-the-art OpenFlow table-miss handler.
