| 摘 要： | 针对一般Qos路由算法没有考虑网络负载平衡以及与传统路由算法共存的问题，设计并实现了多路径QoS路由算法．该算法应用启发式搜索策略，计算出多条满足QoS要求的路由，并根据实际网络负载情况自适应调整路由策略、动态选路，以平衡网络负载，减少网络局部拥塞．仿真实验结果表明：该算法提高了网络资源利用率，并能与传统算法良好共存，具有较好的网络性能．

| Abstract: | Common QoS routing algorithm does not take the balance of network load into consideration as well as does not think of how to collaborate with the traditional shortest-path algorithm. Aiming at these defects, a multi-path QoS-based routing algorithm is designed and realized in this paper. Using heuristic searching strategy, this algorithm can find multiple routes meeting QoS need, adjust self-adaptively and route dynamically according to the actual network load. The result of simulation experiment indicates that this algorithm can balance network load and heighten the utilization ratio of network resource. Also it shows that it can coexist with traditional shortest-path algorithm excellently and has a preferable network performance. |
