Weighted Fairness and Correct Sizing of the Secondary Transit Queue

Summary: Weighted Fairness and Correct Sizing
of the Secondary Transit Queue
in Resilient Packet Rings
Mete Yilmaz and Nirwan Ansari
Abstract--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 net-
works. After a brief overview of the IEEE 802.17 RPR proto-
col, this article investigates the weighted fairness aspects as
well as the requirements for sizing the secondary transit
queue of IEEE 802.17 RPR stations (in the aggressive mode
of operation). The analysis and suggested improvements
presented in this article are then supported by performance
evaluation results and theoretical calculations.
