SLA aware dynamic bandwidth allocation for EPONs

Ethernet passive optical network (EPON) is one of the most promising broadband access networks. We propose a dynamic bandwidth allocation (DBA) scheme for service differentiation that meets the service level agreements (SLAs). Proposed DBA scheme provides predictable average packet delay and delay jitter of expedite forwarding (EF) traffic without the influence of load variation. Performance evaluation shows the effectiveness of proposed DBA scheme.
