基于多层共享备用路由器的多层网络恢复

The Restoration of Multilayer Optical Network Based on Multilayer Shared Backup Router

目前的网络结构是由光传输网络和IP网络共同组成的多层网络,而在多层网络中网络资源的保护和恢复机制是运营商关心的问题。传统的多层网络恢复机制有不同程度上的资源浪费问题,所以本文中基于多层网络架构提出了一种利用多层共享备用路由器的方法来实现网络资源的保护和恢复,这些备用路由器共同组成一个备用池可作为网络拓扑中所有需要保护的路由的替补,在网络出现故障时,作为备用的路由器可提供服务并恢复网络故障,在网络资源设置方面与传统的多层网络保护机制相对比,最终结果表明本文提出的保护措施在成本投入和需求的设备资源上要少于传统方法。

The current network is composed of optical transport network and IP network, and in the multi-layer network, network resources protection and recovery mechanism is the concern of operators. In this paper, based on the multilayer optical network architecture, a method of multilayer shared backup router is proposed to realize the protection and restoration of network resources. In the aspect of cost, compared with the traditional multilayer network protection mechanism, the final result shows that the proposed scheme has a better performance than the traditional scheme.
