摘　　要：随着网络规模的不断扩大，新的IPv6协议将取代IPv4成为下一代互联网的核心协议，而应用于IPv6环境的数据包分类技术也成为包分类研究的热点。本文对RFC算法在IPv6环境下的适用性进行了分析，提出了一种适用于IPv6的递归流包分类算法RFCv6，将RFC算法推广到IPv6环境中，通过提取特征规则的方法，抑制地址长度增长所带来的内存膨胀。仿真结果表明，RFCv6算法取得了分类速度和内存需求的良好平衡。Along with the unceasing expansion of network scale, the new generation of network protocol IPv6 instead of IPv4 becomes the next generation Interact standard and packet classification tecnology applied to IPv6-network is becoming the hot spot of this field. After evaluating the application values of RFC algrorithm under IPv6 environment, RFCv6, a modified RFC algrorithm applied to IPv6-network, is proposed in this paper, designing a method of picking up character rules to excessive memory consumpution incurred by the increase of address size from 32bits to 128 bits. The simulation results show the outstanding performance of RFCv6 in memory demand and classification speed.
