Priority Swapping Intra-ONU Bandwidth Allocation Algorithm
Motivation
Most DBA algorithms focus on OLT-ONU bandwidth allocation but EPON is expected to be a truly converged network supporting voice communication, videoconferencing, real-time and near real-time transactions and data traffic for which it must guarantee appropriate performance to such applications. Therefore we propose an intra-ONU Priority Swapping (PS) algorithm, supporting the three classes of differentiated services namely the Expedited Forwarding (EF), Assured Forwarding (AF) and Best Effort (BE) classes.
Current Progress
Priority Swapping Intra-ONU Algorithm
The proposed priority swapping solution is an intra-ONU bandwidth allocation algorithm focusing to stabilize the delays between the three classes of differentiated services by protecting low priority class (i.e., BE) packets from starvation through priority swapping while providing justifiable amount of bandwidth to higher priority (i.e., EF and AF) queues. The algorithm swaps the priorities of these classes based on the relative buffer sizes of these classes.
