Abstract: Aiming at the problem of unbalanced traffic schedule in multiple logical links, a traffic schedule model of logical links is analyzed, and the method of available bandwidth measurement is proposed. In order to depict the load of logical links clearly, the concept of maximum proportion of available bandwidth is drawn. The amount of traffic which is scheduled in special logical link is calculated. Experimental result shows that the algorithm has better ability of traffic schedule, optimizes the character of traffic load balance in multiple logical links and improves the utilization of logical links.

Key words: link bandwidth, traffic schedule, bandwidth detection, load balance

摘要： 针对多逻辑链路间流量调度不平衡问题，分析逻辑链路流量调度模型，给出逻辑链路可用带宽计算方法，提出“可用带宽比”指标，以更准确地刻画各链路负载状况，量化特定链路上调度流量的大小。仿真实验证明，该算法有较好的流量调度能力，能有效控制各链路的流量，改善多链路间负载均衡，提高链路利用率。
