Weighted Fairness in Resilient Packet Rings

The IEEE 802.17 is a standardized ring topology network architecture, called the resilient packet ring (RPR), to be used mainly in metropolitan and wide area networks. This paper presents an overview, and focuses on the weighted fairness aspects of IEEE 802.17 RPR (in the aggressive mode of operation) by showing performance evaluation results and suggesting improvements. These aspects have not been well studied until now, and can be used to alleviate some of the issues observed in the fairness algorithm under some scenarios.
