| 摘 要： | 设计了IPv6时间戳扩展报文，用于记录报文通过路由器的时间。利用这类报文提出一种IPv6网络测量模型用以获得链路利用率。探测源端主动向网络发送带有时间戳扩展报文的探针，路由器逐跳记录报文通过的当前时间，通过改进型链路利用率统计算法处理，获得链路利用率。同时利用IPv6报文头部的业务流字段，设置专门用于测量的测试级以减少其对网络中已有业务的影响。仿真证明报文设计合理，IPv6链路利用率测量方法可行。

| Abstract: | A new extension header “the time stamp extension header” for IPv6 network is designed in order for recording the time when the packets pass the router. Using the packets, an improved measurement model of link utilization in IPv6 networks is proposed. The source sends probe packets with the time stamp extension header and the current time is recorded in the packets。With the processing of improved link utilization statistic algorithm, the link utilization is therefore obtained. Meanwhile using the special fields in the IPv6 header, the “test level” is designed to eliminate the influence of the current traffic. The approach is verified through simulations |
