| 摘 要： | 目前Internet网络环境下,网络参数的随时变化容易造成路由过期,从而使提供的QoS路由无效,为此提出了一种适合参数动态变化的单播QoS路由算法(DPA),该算法在路径代价随时间不断变化的情况下能够自主地选择最优路由节点,解决多约束QoS单播路由选择不精确的问题.实验表明,本路由算法自适应性和扩展性较好,同时在路由选择方面比传统的路由算法能够提供更好的QoS路由. |

| Abstract: | In the current Internet routing under network environment,network parameter changes all the time,which easily causes the problem of routing expired,makes the provided QoS routing invalid.In order to solve these issues,this paper proposed a QoS unicast routing algorithm (DPA) suit for the dynamic change of network parameters.In the case of the path to changing costs over time,it can select the optimal routing node autocratically to solve the routing inaccuracies problem in multi-constrained QoS unicast routing.Experimental results show that the routing algorithm is better in adaptability and scalability,in the meantime,compared to traditional routing algorithms,DPA can provide better QoS routing in the route selection. |
| Keywords: | Dynamic parameters QoS Unicast routing Adaptability |
