摘要
针对现有变电站信息传输的不足,提出了基于类的权重公平调度策略和加权随机预侦测的信息传输策略。通过模糊层次分析法计算不同等级的信息的传输权重因子,根据结果划分相应的最小带宽及分组丢弃概率来实现数据传输的服务质量(QoS)要求。并采用网络仿真法,对方案的有效性进行了定量评估。仿真结果表明了该策略的有效性。
In order to overcome the shortcomings of currently used flow control methods for information transmission in substation, the information transmission strategy based on class-based weighted fair queuing （CBWFQ） and weighted random early detection （WRED） is proposed. The weighted transmission factor of information is calculated by the fuzzy analytic hierarchy process （FAHP） and the minimum bandwidth and discarding possibility are divided to satisfy the requirement of information quality of service （QoS）. Network simulation is employed to verify the performance of the strategy proposed and the results indicate the validity of this strategy.
