摘要
将EPON与WLAN相结合,设计了一种基于BoF的WLAN与EPON融合接入方案。探讨了系统的上行带宽分配机制,给出了ONU-AP在竞争期和非竞争期对STA的带宽分配策略。OLT采用带宽预测的方法实现了ONU-AP的带宽分配,完成了EF业务和AF业务的带宽预测。最后,给出了具体的带宽分配算法。
The paper combines the EPON and WLAN,designs a WLAN and EPON amalgamation access project based on BOF. Up-stream bandwidth allocation mechanism of the system is discussed, and the bandwidth allocation strategy from ONU-AP to STA is put forward in contention period and contention-free period. OLT adopts the bandwidth forecast method to realize the bandwidth allocation from OLT to ONU-AP, accomplishes the bandwidth forecast of EF operation and AF operation. Finally the paper brings forward the idiographic bandwidth allocation algorithm.
