IP网分级寻址模型的研究

A model of hierarchical addressing in IP networks

为解决IPv4地址空间耗尽和路由表爆炸问题,提出一种建立在网络分簇基础上的IP网分级编址与寻址模型(IPEA).这种编址方式优于以往的扩展IP地址空间模型的编址方式,它将每个地址的层次通过地址本身体现出来,这种层次的区别不仅省去中间路由器为正确路由而对包的地址修改,还将路由表长度减小到本地簇中的结点数目.实验结果表明IPEA模型比Kleinrock模型在缩减路由表长度与控制路由路径长度增长方面更有效率.这种层次寻址模型有效地解决了IPv4地址空间耗尽和路由表爆炸问题.

To solve the problems of IPv4 address space exhaustion and routing table explosion, a model based on the clustering of networks was developed that utilizes multi-tier numbering and addressing in the Internet （IPEA）. This addressing model has advantages over other IPv4 address space extending models： the layering of addresses is embodied by the addresses themselves and the differentiation of layering of addresses not only saves the intermediate routers from altering the addresses in the headers of packets but also reduces the length of routing tables to the size of the local cluster. Analysis proves the accuracy and interoperability of the IPEA.
