Abstract

Ethernet passive optical network (EPON) has combined the advantages of Ethernet and passive optical network (PON). High speed accessing at lower price has been realized in this way. In this paper, based on CBR (constant bit rate), design issues of dynamic bandwidth allocation (DBA) are studied and the improved DBA algorithm is proposed. ensure effectively quality of service (QoS) of the entire EPON and fairness of bandwidth allocation, and meet the request of the current network with multi-service, multi-level priorities. Provide reference for the standard of multi-service QoS in EPON uplink bandwidth allocation.
