Abstract:
？目前流量工程的主要算法大多不能克服对不同类型业务流顺序的影响以及对各流类型带宽比例的影响，且很少在为业务请求计算路由时便考虑避免LSP抢占的问题。为此，提出一种避免抢占的MPLSDS-TE路由算法PA-DTE（PreemptingAlgorithm-DiffServawareTrafficEngineering）.新算法综合考虑各类业务流的带宽比例，优先选择相对空闲的链路，从而减少了被抢占的LSP数目。为验证新算法的性能，在NS2仿真平台上实现了该算法的仿真，仿真结果表明，与在为业务请求计算路由时未考虑避免LSP抢占问题的算法相比，新算法在负载均衡、维持链路各CT(ClassType)流量比例、保证业务QoS和避免抢占等方面表现出了一定的优势。
