    ClassBenchv6: An IPv6 Packet Classification Benchmark

    Recently, the significantly increased IPv6 address length has posed a greater challenge on wire-speed router for Packet Classification (PC). Most conventional IPv4-based PC algorithms are no longer suitable for IPv6 PC. The performance and capacity of many IPv6 algorithms and classification devices depend upon properties of the IPv6 classifiers. However,...
