【摘要】 提出了模糊路由选择（ＱｏＳ－ＦＲ）模型，定义一组隶属函数来反映对某个度量值的ＱｏＳ要求，基于模糊规则推理出每条路径的模糊代价．ＱｏＳ－ＦＲ在全网范围内均衡负载，从而减小了链路上拥塞的概率．仿真结果表明，在保证ＱｏＳ的前提下，该方法可获得更高的链路利用率和更大的吞吐量．更多还原

【Abstract】 In this paper. a fuzzy QoS routing (QoS-FR) model is proposed. A set of membership function is defined to reflect the QoS requirements for each metric. Based on fuzzy rules, a reasonable fuzzy cost is inferred and assigned to each path. The QoS-FR model takes into consideration the balancing of the load in the network to avoid congestion. Simulation results demonstrate that the proposed QoS-FR can produce high throughput and superior link utilization while keeping the QoS guarantee.更多还原
