| 摘 要： | 分布式排队双总线（ＤＱＤＢ）协议采用带宽平衡机制（ＢＷＢ），保证了在网络重载时，在每个结点浪费掉一部分带宽的条件下，达到全网带宽分配的公平性，但它还存在着先级管理和达到公平性稳态的时间较长等问题，在分析造成这些问题的原因的基础上，提出了一种更为有效地解决带宽分配公平性的方法，即具有时隙重用功能和抢占优先功能的，多请求多优先级ＢＷＢ计数器的媒质接入控制机制（Ｍ－ＤＱＤＢ）。这种新方法在保持原协议特点

| Abstract: | The bandwidth balancing(BWB) mechanism is used in the Distributed Queue Dual Bus(DQDB) protocol and the fairness of the bandwidth in overload can be achieved by forcing each node using a fraction of the available bandwidth for transmission. The problems in the protocol, such as priorities management and long instant delay, were studied, and a better solution called Slot Reused and Preemptive Media Access Control mechanism with Multiple Requests outstanding and Multiple BWB Counters for different priorities was presented, which further improves the fairness of the distributed queue protocol with its characteristics unchanged. |
