基于覆盖网构建的网络多链路故障恢复策略

Recovery Strategy from Network Multi-link Failures Based on Overlay Network Constructing Technique

为解决网络频繁出现瞬时多故障引发的网络失效、数据丢失等问题,借鉴弹性路由层思想提出一种基于覆盖网构建的网络多链路故障恢复策略。根据底层网络特点在上层构建弹性的覆盖网节点及链路,当网络发生故障时迅速选择合适的覆盖网弹性层进行数据无中断转发。仿真结果表明该方案可以提高网络在多链路故障时的数据包转发可达率,缩短平均路径长度。

A scheme for network multi-link failures recovery with the idea of resilient routing layer based on overlay network constructing is proposed in order to settle network invalid and data lose that is triggered by network instant multiple failures. According to the underlay network characteristic constructing resilient nodes and links in overlay network, selecting suitable routing layer to forward data once a failure occurs. The simulation result shows that this scheme can not only improve network packet reach ability, but also shorten average path length.
