针对QoS路由中流量动态请求的情况,并考虑到现有路由算法的不足,提出一种采用区分服务模型处理QoS请求的基于约束集网络分区策略的路由算法,对算法的有效性和可行性进行了分析.在此基础上进行了时间更新频度分析,得出了流速和更新频度的优化关系.采用Lingo环境对路由优化进行模拟,测定了流速和路由计算时间间隔的关系.实验结果表明,在较小的更新频度下,可以获得较大的链路流量,降低了路由更新频率并得到较高的计算效率,实现了较高的网络资源利用率.
In view of the situation of dynamic traffic request in QoS routing, and taking into account the shortcomings of the existing routing algorithms, this paper proposes a routing algorithm based on constrained set network partitioning strategy that uses QoS model to process QoS requests. The validity and feasibility of the proposed algorithm Analyzed the relationship between flow rate and update time, and then got the optimal relationship between flow rate and update frequency.Lingo environment was used to simulate the route optimization, and the relationship between flow rate and route calculation time interval was determined.The experimental results show , With a smaller update frequency, larger link traffic can be obtained, the routing update frequency is reduced and a higher computational efficiency is achieved, and a higher utilization of network resources is achieved.
