摘要
提出了一种用于 Internet中服务质量控制的报文分组调度与丢弃算法 .该方法根据用户要求的服务质量 ( quality of service,简称 Qo S)参数和多媒体应用的类型以及等待时间等因素 ,综合调度路由器中所到达的报文分组和分配缓冲 ,使其能够满足用户所要求的服务质量 .计算机模拟表明 ,该算法的转发性能等指标要优于当前常用的调度算法——加权公平队列法 ( weighted fair queuing,简称 WFQ) 。
In this paper, the authors propose a scheduling and dropping algorithm for packets in QoS (quality of service) controlling for Internet. This method is based on the QoS parameters required by users, the types of multimedia and the waiting time, etc. It schedules the packets arriving in a router and allocates the buffers to meet the quality of services. The computer simulation shows that the forwarding performance of the proposed algorithm is superior to the WFQ's (weighted fair queuing), which is the common scheduling algorithm used in routers. So, this algorithm improves the transmission of multimedia information on Internet.
