Multi-Object Optimal Anycast Routing Algorithm Based on Differentiated Service Model

针对常见的单目标最优化选播路由算法存在的问题,通过改进链路上的带宽分配机制,提出了一种基于区分服务模型的多目标最优化选播QoS路由算法,为用户提供了分等级的服务,使用户公平有效地使用网络资源．并根据建立的多目标最优化选播模型,采用改进的非支配排序遗传算法来求解此模型．随机网络模型的仿真结果表明:此算法快速、有效,是一种值得推广的快速算法．

For solving the problems of single-object optical anycast routing algorithm, in the paper, we present a Multi-Object Anycast Routing Algorithm Based on DiffServ Model with QoS requirements by improving the distributing mechanism of link bandwidth. It provides different serves and uses the network resource fairly and effectively. The NSGA- Ⅱ is proposed in the paper to solve the Multi-Object Optical Model. The simulation results show that the algorithm is fast and effective and can be used widely.
