摘要 该文研究了业务量疏导WDM网状网中如何建立可靠的业务连接问题,提出一种新的基于共 享风险链路组(SRLG)限制的共享通路保护算法。该算法既可以保证用户业务不同的可靠性要求,同时又 能够有效提高全网的资源利用率,从而大大降低全网的业务阻塞率.该文还对所提算法进行了仿真研究,并 给出了仿真结果。 This paper addresses the dynamic establishment of dependable connections for grooming WDM mesh networks. A shared path-protection algorithm under Shared Risk Link Group(SRLG) constraints for multi-granularity traffic is proposed. The presented scheme establishes SRLG-disjoint primarily and backups traffic stream paths between the source-destination node pairs and reduces the spare capacity. It provides the same level of protection against single SRLG failure as dedicated path-protection scheme. Moreover it is better than dedicated path-protection scheme in network utilization. Network performance, based on dynamic traffic with different load, is investigated via simulations. The results show that the scheme can improve the performance of the network significantly.
