摘 要: 针对多约束QoS路由问题,将其转化为一个多约束赋权图最优路径问题,选择费用、带宽、时延和丢包率为参数。采用基于遗传算法的QoS路由选择算法,算法采用网络消耗和负载分布平衡为目标函数,目的在使用最小网络资源的基础上,使网络达到负载平衡,降低网络拥塞,降低丢包率,提高服务质量。仿真试验结果表明,该算法具有较好的性能。 A new multi-restriction weight graph approach of best path which contains four parameters (cost, bandwidth, delay and package loss) aimed at multiple constrain problem of QoS route is presented. A QoS route algorithm is introduced based on genetic algorithm which utilizes objective function made by network consumption and load distribution equilibrium for balancing network load, reducing congestion and package loss, enhancing quality of service. The simulative experiment illustrates that the algorithm has a better capability than traditional approach.
