| 摘 要： | 针对传统距离矢量路由(Bellman-Ford)算法,将多约束路由问题简化,并改进路由问题的限制条件,提出了改进的Bellman-Ford算法,应用于基于集中式控制路由协议网络模型。仿真结果表明,采用改进算法的网络路由计算时间随网络节点数有明显的改善,且网络阻塞率随路由请求数增加而下降。验证了改进算法比传统算法更加有效。

| Abstract: | Amelioration of Bellman-Ford algorithm is deduced in the letter based on traditional Bellman-Ford algorithm and applied to CCRP networks. The simulation results demonstrate that calculating time of networks adopted amelioration of Bellman-Ford algorithm is better than that of adopted Bellman-Ford algorithm with node number increasing and block ratio of networks is declining with request number increasing. |
