摘要

摘要：综合业务请求的服务质量（QoS

quality of service）要求、节能要求，以及遭遇单链路或单个节点失效时的生存性要求，提出了一种多粒度传送网中的绿色单播路由保护机制。基于K 最短路径算法，计算符合 QoS 需求的路径；根据最小波长转换次数，在多层辅助图上进行资源分配；根据业务请求的保护等级，提供了三级保护机制。仿真实验基于EON（Europe optical network）拓扑，通过与现有机制在阻塞率、保护/工作资源比和负载均衡度方面的性能对比，表明提出的机制是可行且有效的。

Abstract

The mechanism for green unicast routing protection is designed with the constraint of quality of service (QoS)

energy consumption and the survivability of single link or node failure considered.The path is calculated under the constraint of QoS based on K-shortest path algorithm.The resource allocation is done on multi-layer auxiliary graph considering the minimum times of wavelength conversion.Three protection levels are provided according to the service demands.The mechanism is implemented over EON (Europe optical network) topology by simulation.Performance evaluation has been done on the blocking probability

the protecting/working resource ratio and the load balance degree by comparing with certain existent mechanism.It has been shown that the proposed mechanism is both feasible and effective.
