摘要
本文主要介绍了有关IPv6互联网的网络地址结构及其管理机制。与现行的IPv4地址相比 ,IPv6在地址的长度、分类方法、表示方法和类型等方面均不相同 ,它可有效地解决IP地址枯竭与路由效率低下的问题 ,同时具有地址聚类性、多播性、任播性和接口多址性等特点 ;而在IPv6地址管理方面则采用层次化路由选择策略 ,支持QoS路由协议 ,将地址解析通过邻居发现协议来实现 ,新增了无态地址的自动配置 ,使得网络地址的重新编号变得更加简单快速。最后通过模拟仿真的方法 ,进一步分析说明了IPv6网络的性能。
IPv6 addressing architecture and administration are introduced in this paper. IPv6 address differs from IPv4 in the length, types and binary addressing notation. So it has many new features such as routing aggregation, anycast and multicast, etc. IPv6 fully resolves the problem of address space depletion and router inefficacy. The IPv6 addressing management adopts the strategy of hierarchy routing. So it can support QoS routing protocol, resolve MAC address by neighbor discovery protocol, and add address stateless autoconfiguration to simplify network management. This paper finally analyzes the performance of IPv6 in detail by simulation.
