摘要
为解决传输SDH环路组网(即双路由组网)的机制限制,结合四川5·12地震后在多路由组网抗击灾难影响的实际应用,提出利用传统SDH设备进行多路由、多局向组网的方案。在充分利用现有传输资源、节省投资的前提下,提出SDH多路由的网络方案,达到类似"ASON"组网效果,增强网络的抗多点中断的能力,保证网络的安全、稳定运行。
In this paper,we present the renovation and study of multi-route networking for SDH.In order to resolve the limit of SDH ring-networking,multi-route and muti-office direction networking based on the current traditional SDH network is proposed,considering networking practice made to resist the following destroy of ＂5.12＂ earthquake in Sichuan province.On the premise of fully using current SDH resources and saving investment,the program can make the SDH network gain the similiar stability of ASON,which not only enhances the ablility which resists the muti-point break,but also ensures the safety of network.
