WDM局域网调度多播业务随机算法的研究

Research on Random Algorithms for Scheduling Multicast Traffic in WDM LAN

在一个波分复用 (WDM)的广播网中 ,寻找一种最优化消息调度方案比较困难。提出两种调度方案 :第一种方案为连续重传一条消息 ,直到它的所有目标节点都接收到该消息 ;第二种方案为在两次重传消息之间引入一个随机时延。通过模拟显示 ,在第二种方案中系统具有更高的吞吐量。

Since optimal message scheduling in a WDM network is known to be very difficult,we study two simple scheduling schemes:in the first,a message is continuously retransmitted until it is received by all of its intended recipients;and in the second,a random delay is introduced between retransmissions of the same message.By simulation,the second scheme results in higher throughput.
