本文从提高系统的带宽利用率的角度出发，充分利用网络流量的自相似 特性，提出了一种能有效提高上行带宽利用率的动态分配算法-In this thesis， dynamic bandwidth allocation algorithm TGOGT where the two groups of ONU are granted in turn and allocation bandwidth according to the characteristic of network traffic

完成了EPON上行数据的传输，实现了动态带宽分配算法-this file complete a basic upstream data transmission of EPON MAC protocol.

EPON与WiMAX(Worldwide interoperability for Microwave Access,全球微波互联接入)结合，提出新EPON信息传输模型，建立新的综合DBA算法即双重优先级算法。(Combining EPON with WiMAX global microwave interconnection, a new EPON information transmission model is proposed, and a new integrated DBA algo
