| 摘 要： | 介绍了一种WDM-EPON的DBA算法并对其进行改进,改进的算法能根据ONU端不同的业务类型情况对波长和带宽进行分配,以支持多业务接入的QoS,从而使整个网络带宽的得到更公平有效地分配,最后用OPNET进行仿真,结果表明改进的算法能为不同等级的业务流提供相应的带宽,时延等QoS保证.

| Abstract: | A kind of dynamic bandwidth allocation(DBA) algorithms of WDM-EPON which provides a promising upgrade scenario for current single-channel TDM based EPON was studied and improved. Wavelengths and bandwidth are distributed according to the services types in ONU by the advanced DBA algorithms in order to guarantee the QoS of the miltiple-services access,making the whole network bandwidth allocation fair and efficient. The simulation results based on OPNET indicates that the improved DBA algorithms performed we... |
