Characterizing Rule Compression Mechanisms in Software-Defined Networks.
PAM(2016)
摘要
Software-defined networking (SDN) separates the network policy specification from its configuration and gives applications control over the forwarding rules that route traffic. On large networks that host several applications, the number of rules that network switches must handle can easily exceed tens of thousands. Most switches cannot handle rules of this volume because the complex rule matching in SDN (e.g., wildcards, diverse match fields) requires switches to store rules on TCAM, which is expensive and limited in size.
