摘　　要：本文提出了一种可调信道访问光波网以及适合于该网的介质访问控制协议Ｍ－ＤＱＣＡ，利用波分复用技术将双总线光波网分成多个并行信道，用一个信道专门传输等时业务和请求信息，使网络管理得到简化；利用时隙重用技术，提高了网络的吞吐量；拥塞控制方法与多跳网相比简单得多，各用户只需根据本站缓存的情况来控制输入业务的流量。计算机仿真表明，Ｍ－ＤＱＣＡ光波网具有很好的性能。A Lightwave network with tunable channel access and a medium access control protocol named M-DQCA are introduced in this paper.With the wavelength division multiplexers,parallel channels are provided.One of these channels is used to transfer isochronous traffic and request signal, which makes the network management simpler. The network throughput is increased through slot reuse.The users control the input traffic according to the situation of their buffers,which makes the congestion control mechanism simpler compared with that of multihop lightwave network. Computer simulations display the performance of M-DQCA lightwave network.
