| 摘 要： | 对一个基于单域ASON仿真平台扩展实现了多域ASON仿真平台.通过对网络节点Id进行分域,实现了ASON中的多域分层网络结构,引入了一种基于全网抽象的路由信息汇聚策略.在ASON网络的分层路由中的每个路由域中加入备份Speaker节点,使网络具有更好的生存性.仿真测试表明当网络规模较大时,多域ASON网络在拓扑收敛速度、连接建立时间等方面的性能均优于单域.

| Abstract: | In this paper,a multi-domain ASON simulator based on a single domain ASON simulator is devel-oped.By dividing a node's Id into several domains,a multi-domain hierarchical network structure is realized.Then a Topology aggregation scheme based on mesh network abstraction was introduced.What's more,the Hierarchical routing algorithm in ASON was improved by adding a backup Speaker node to each routing do-main,which makes network survivability much better.Simulator tests show when a network' scale is relative-ly... |
