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
