多优先级业务流局部化多路径QoS路由算法

Localized multi-path QoS routing algorithm for multi-priority traffic flows

全局QoS路由需要获知精确的全局网络QoS状态。由于不可忽略的传播延时和处理开销,节点所获得的QoS信息总是不精确的。研究了节点只了解部分的网络状态信息的情况下,当网络中存在具有优先级差异的多类别业务流时可行的局部QoS路由策略。仿真结果验证了算法的有效性。

Global QoS routing algorithms require precise delay and dynamic processing overhead, it is difficult for nodes global network QoS states. Due to non-negligible propagation to maintain the precise global QoS information. A localized QoS routing scheme was proposed in the case when there are flows of different priorities and nodes only know partial state information of the network. Simulation results demonstrated that the algorithms can achieve good performances.
