Link-lifetime-based service restoration in optical datacenter network
Aiming at the correlated and cascading failures caused by large-scale disasters,a post-disaster service restoration scheme was proposed.This scheme utilized global service bandwidth concession and the limited lifetime of local links to mitigate resource crunch in the post-disaster network.According...

| description | Aiming at the correlated and cascading failures caused by large-scale disasters,a post-disaster service restoration scheme was proposed.This scheme utilized global service bandwidth concession and the limited lifetime of local links to mitigate resource crunch in the post-disaster network.According to their bandwidth and holding time requirements,the impacted services for restoration was prioritized firstly,then jointly employed anycast and manycast routing strategies to improve the service connectivity and bandwidth resource utilization.Simulation results show that the proposed scheme can significantly reduce the service loss ratio,effectively prolong the holding time of the impacted services and decrease the data flow loss ratio in the post-disaster network. |
