摘　　要：针对单跳波分复用（ＷＤＭ，Ｗａｖｅｌｅｎｇｔｈ Ｄｉｖｉｓｉｏｎ Ｍｕｌｔｉｐｌｅｘｉｎｇ）访问控制协议中的两大难点：可调光器件的调谐时延比较大，以及网络的传播时延相对于单位分组的传输时延比较大，本文提出了几种数据传送算法，这些算法都是以信息最早地无接收碰撞传送为基本目标，本文对这些数据传送算法的基本特性进行了分析。There are two major problems inherent in medium access protocols for single hop WDM networks.One is the relatively large tuning latency of the tunable transceiver.Another is the relatively large ratio of the propagation delay to the packet transmission time.To address these problems,this paper presents several scheduling algorithms,which are basically aimed to the earliest transmission without receiver collision.The paper proves the basic properties of the algorithms.It also compares and analyzes the performance through extensive simulations.
