A Priority Dynamic Upstream Bandwidth Allocation Algorithm for QoS Over Ethernet PONs

Ethernet Passive Optical Networks (EPONs) are envisioned as a promising network technology to provide low cost high-speed solution for end user access to the broadband network. Ethernet is attractive because of the price declines in both fiber optics and Ethernet components. One of the issues that need to be addressed on EPONs is the ability of users to share a common upstream channel effectively and efficiently. This calls for an efficient bandwidth allocation algorithm to statistically multiplex among end users. In addition to just bandwidth allocation, there is concern about providing high Quality of Service (QoS) to end users. Thus, one of the major goals for researchers is to devise an upstream dynamic bandwidth allocation algorithm that provides a high level QoS.
