Resilient Packet Ring (RPR) is a new technology being standardized in the IEEE 802.17 working group. This paper presents the performance of 1TB-RPR, a proposal made to the working group. 1TB-RPR deploys a rate-based fairness algorithm rather than the quota-based algorithm that has been widely used in legacy ring schemes. This fairness algorithm significantly reduces access delays under steady state and allows RPR to be scalable in today's MAN/WAN environments. A ring access delay bound under
