Abstract: Considering the unstable traffic of multi-logical links in broadband network access, this paper proposes a model of token scheduling in multi logical links. Token is distributed dynamically in multi-links to make the traffic tend stable and realize traffic load balancing. Simulation results show that the model has better ability of traffic control, which can control the traffic of links according to the demands, and the character of time response and utilization of logical links are improved.

Key words: token scheduling, dynamic distribution, traffic shaping, load balancing

摘要： 针对宽带接入多逻辑链路中普遍存在的流量不稳定问题，提出一种多逻辑链路间令牌调度模型，通过在多链路间动态调度令牌，使链路的流量趋向稳定分布，达到流量负载均衡的目的。模拟实验结果证明，该模型有较好的流量调控能力，能根据实际需要控制各个链路的流量，改善出口时间响应特性，提高链路利用率。
