摘要
IPv6作为新一代的互联网协议,对IP网络的服务质量提供了很好的支持,尤其是其报头中20位的流标签的使用,更是比IPv4的尽力而为服务有了很大的提高。本文介绍了IPv6流标签的定义和使用规范,分析了流标签在两种主要体系结构中对QoS如何支持,并用实际数据分析表现出流标签对于传统协议更能较好的支持QoS。
As the next generation Internet Protocol,IPv6 defines 20-bit Flow Label to support QoS of some new applications,and it provide service better than pure ＂best-effort＂ delivery.In this paper,we introduced the definition and use of norms of the Flow Label,analysed the methods to use Flow Label to support quality of service in IntServ and DiffServ.Finally we analysed the advantages of packet classification that used Flow Label with simulation data.
