摘　　要：作为媒质共享的树型网络,吉比特无源光网络(GPON)需要媒质接入控制(MAC)协议协调各终端对上行信道的访问,避免冲突.针对目前没有适合GPON系统的媒质介入控制协议,根据G.GPON.gtc建议对GPON系统帧格式的定义,提出了一种体现业务优先级的MAC协议,给出了授权分配情况,分析了协议的有效性,并给出了协议的计算机仿真的结果.As media-shared network, gigabit-capable passive optical networks (GPON) needs some form of media access control (MAC) protocol to arbitrate the upstream channel among terminations, and avoid collisions. But there is no media access control protocol suitable for GPON system up to now. A MAC protocol for GPON system according to the ITU-T G.GPON.gtc was brought forward and analyzed based on computer simulations. And it is approved effective in practice.
