摘    要:IPv6定义了一种新型的地址——Anycast地址.它允许一个数据包被路由到具有相同Anycast地址的一组网络结点中的任一个结点,具有广泛的应用前景.但由于地址选取和地址的非层次聚合等问题,目前还没有标准的支持Anycast服务的网络层路由协议.基于IPv6网络的支持Anycast服务的系统构架和路由协议(HHA)能够有效地克服这些问题,提供网络层的Anycast服务,在网络中平衡,广泛地分布路由负载,并且可以部署在即使不支持它的网络中.

关 键 词:Anycast  IPv6  HHA  散播  Anycast域  顺带过程

Abstract:IP version 6 defines a new type of address, known as "Anycast" address that allows a packet to be routed to one of a number of different nodes all responding to the same address It has numerous potential applications Because of some difficulties such as address selection and the defiance to the hierarchical aggregation, there has not been a successful network layer Anycast routing protocol The routing protocol for Anycast service (called HHA) over IPv6 network can overcome these difficulties by providing the network with Anycast services and distributing the Anycast routing information in the network evenly and widely, and it even can be deployed in the network that does not support the architecture
Keywords:Anycast  IPv6  HHA  dispersion  Anycast domain  pass  by process
