摘　　要：本文针对可调发送机/可调接收机(TT/TR)的单跳波分复用网络提出多种无接收碰撞的访问控制协议,包括简单的无接收碰撞的数据传送策略TS和按最早发送时间进行优化的两种数据传送策略ETS、METS。计算机模拟结果说明优化的数据传送方案可以获得十分优良的网络性能,是WDM网络中行之有效的访问控制协议,尤其是METS协议能在可调光器件的调谐时间较长时依然保持非常突出的性能。对于采用任意调谐时间的可调光器件的WDM网络,METS具有相当重要的实用价值。This paper presents several protocols without receiving collisions for WDM networks with tunable transmitter/tunable receiver architecture. These protocols include the simple non-receiver -collision protocol (called TS), the optimized scheduling (called 'E/TS) and the modified ETS (called METS). Computer simulation indicates that these algorithms achieve extremely good performance. They are the efficient media access protocols for WDM networks. Moreover, the METS algorithm shows more outstanding performance with the increasing of the tuning time of optical device. It is with great practical value for the WDM network with arbitrary transceiver tuning latencies.
