GMPLS多层网络的分布式路由计算

Hierarchically distributed route computation server in GMPLS multilayer networks

GMPLS技术引入的多层复杂性给源路由器带来了极大的压力,也造成了LSP建立的延时。为了缓解这种影响,文章提出了一种分布式的路由计算技术:域间和域内的路由选择分别由所辖范围的分层、分布路由器来完成。它能减少路径建立的时延,并能依据每个GMPLS域或者每层的路由选择机制做出较OSPF更为灵活的路由选择。

Multilayer complexities introduced by GMPLS, put great pressure on source router, as well as induction of delay of LSP set-up, To relieve above problems, hierarchically distributed route computation servers are put forward. That is, interdomain and intradomain routes are achieved by matching servers in their own region, respectively. It will reduce the routes set-up delay and make more flexible routing depending on each GMPLS domain or routing in each layer,than OSPF.
