摘要

本文研究了备份重新配置技术，以减轻双近同时链路故障场景的影响。首先，引入了一种改进的模型，以便在第一链路失效后准确识别脆弱连接。然后，开发了一种改进的方法，称为连续备份重新配置(SBR)，用于在线备份重新配置，以进一步减少受影响的连接数量，当没有额外的容量添加到网络中进行重新配置时。复杂性分析和仿真结果表明，SBR在容量效率和执行速度之间具有折衷的优势

An Improved Approach for Online Backup Reprovisioning Against Double Near-Simultaneous Link Failures in Survivable WDM Mesh Networks

This paper investigates backup reprovisioning technique to mitigate the impact of double near-simultaneous link failure scenarios. First, a refined model is introduced for accurate identification of vulnerable connections after the failure of the first link. Then, an improved approach termed Successive Backup Reprovisioning (SBR), is developed for online backup reprovisioning to further reduce the number of affected connections when no extra capacities are added to the network for reprovisioning purpose. Complexity analysis and simulation results show that SBR has advantages in tradeoff between capacity efficiency and execution speed
