Abstract
Ethernet Passive Optical Network (E-PON), which leverages the ubiquity of Ethernet at subscriber locations, seems destined for success in the optical access network. Dynamic Bandwidth Assignment (DBA) provides statistical multiplexing between the optical network units for upstream channel utilization. To satisfy the services with heterogeneous QoS characteristics, it is very important to provide QoS guaranteed network access while utilize the bandwidth efficiently. We propose a QoS-enabled DBA Algorithm for differentiated service in EPONs. The new DBA algorithm is based on the weights of the different classes and the current queue information to perform better per class bandwidth allocation. The specific QoS requirements of different classes are mapped into deterministic effective bandwidth and further used to assign the according weight. We conduct detailed simulation experiments to study the performance and validate the effectiveness of the proposed protocols.
