摘要

In this paper, an (overlap and non-overlap)-based dynamic bandwidth allocation (DBA) algorithm with wavelength optimal length (WOL) for upstream channel in multi-OLT passive optical network (PON) is proposed. By introducing optical line terminal (OLT) pool, the problem of OLT services imbalance is solved. Based on the service and its weight factor, proportion algorithm is constructed to allocate OLTs and wavelengths to OLT pool and wavelength group respectively. By proposing a new concept of WOL, the bandwidth wastage is reduced. By presenting overlap and non-overlap algorithms, the bandwidth utilization is improved further. By the simulation and analysis, the effectiveness of the proposed algorithms is demonstrated.
