摘要： 提出了一个简洁的基于IPv6的报文结构模型，该模型通过对现有IPv6中ICMP路由器发现报文的改进，实现了对网络性能的改善。在该模型中，移动节点到达一个新的子网时，获得转交地址和申请选播服务的实现不必经过以往的两次报文发送－接收过程，而只需一次。该模型对网络性能的改善体现在：缩短转交地址获得和选播服务确定的时间，简化ICMP报文的类型，节约网络带宽资源。

Abstract: In this paper, a concise model of message construction based on IPv6 is proposed. This model promotes the network performance via the improvement on IPv6 ICMP router discovery message, with the minimum influence on the current protocol and algorithm.When a node arrives at a new subnet, the implementation of obtaining care of address and applying anycast service needs only one message send-receive procedure, not two procedures as before. This model shortens the period of obtaining care of address and confirming anycast services, simplifies IPv6 message types, and saves network bandwidth resources.
