The Combination of Statistical Bandwidth Allocation and Dynamic Bandwidth Allocation Algorithm for QoS in EPON

摘要

Based on the standard of EPON and the research results,this paper introduces the mechanism of multi-point control protocol and compares the Statistical bandwidth aIlOcatiOn(SBA) and DynamJc bandwidthallocation(DBA),according these,this paper proposes a new scheduling algorithm to support the quality of services(QoS)in EPON.Here,static bandwidth allocation for guaranteed bandwidth service and dynamic bandwidth allocation for on-demand,dynamic traffic services.
