IP网流量工程的一种权值设置方法

Weight Assignment for Traffic Engineering Using Traditional IP Routing

提出一种新的基于传统路由协议的流量控制方法。该方法首先在不限制总流量条件下求解最小化最大连接利用率。然后在固定最大连接利用率条件下最小化总流量。由此求得最优流量分配方案并从其对偶问题中求出各连接的权值配置。实验结果显示,文中算法较现有算法明显降低最大连接利用率,并且增加了稳定性。

This paper proposes a new traffic engineering method based on traditional IP routing. The method first minimizes the maximum link utilization without imposing traffic is minimized with a fixed maximum link utilization to dual problems, the weight assignment for each link is obtained achieves smaller link utilization than the existing method constraint on the total traffic. Then the total obtain the optimal traffic allocation. From its Simulation results show that the proposed method.
