| 摘 要： | 为了保证OBS网络中不同优先级业务的服务质量和解决偏射算法在偏射控制上的问题,提出一种基于优先级与参数可调的偏射路由算法.该算法通过设置可调参数“偏射概率”来控制冲突突发包的偏射,并从可调丢包率和偏射路径长度意义上寻找最佳偏射路由.当冲突发生时,分割优先级低的突发包,并将分割突发包偏射到空闲的链路上；在空闲的链路中选择...

| Abstract: | In order to guarantee quality of service(QoS) of different priority bursts and solve the problem of deflection control of deflection algorithm in OBS networks,a deflection routing algorithm based on priority and parameter-tunable in OBS networks is proposed.It intercalates the definition of a tunable-parameter(deflection probability) to control the deflection of contending bursts,and searches the optimum deflection path in terms of the burst loss probability and the deflection path length.When competition o... |
