摘要/Abstract

摘要：

针对传统重映射故障恢复算法恢复效率低、服务中断时间长的问题，提出了一种基于等效资源的可重构服务承载网(RSCN)故障恢复算法FRA-ER。算法将故障RSCN恢复问题等价转化为寻找等效资源的问题，一次运算可恢复全部或部分故障RSCN，提高恢复效率；网络重构策略NRA周期性检测恢复后RSCN结构并进行调整优化以节省底层资源开销。仿真结果表明，与重映射算法及快速愈合算法相比，可减少平均恢复时间约15%，NRA平均每次可节省80的带宽消耗，使恢复成功率提高约10%。

Abstract:

Aiming at the low recovery efficiency by using the traditional re-mapping failure recovery algorithm and prolonged interruption of service, a Fault Recovery Algorithm based on Equivalent Resource (FRA-ER) was proposed. The FRA-ER converted the recovery problem to finding equivalent resource problem, achieving to recovery all or part of the fault RSCNs by once. A Network Reconfigure Algorithm (NRA) was also proposed to detect and regulate the RSCNs periodically to optimize their architectures and reduce the costs. Finally, the numerical results show that the proposed FRA-ER could achieve 15% recovery time reduction compared with conventional overall re-mapping algorithm and fast recovery algorithm. The NRA could achieve 80 band reduction on average, improving the recovery success ratio by 10%.
