The IEEE P802.17 workgroup is currently standardizing a ring network architecture and associated protocol called Resilient Packet Ring (RPR). In addition to highpriority guaranteed class A traffic and best-effort class C traffic, RPR supports low-jitter, delay bounded, medium priority class B traffic. This class can, for example, be allocated for VBR(More)
Buffer Insertion Rings (BIR) are known to provide higher throughputs than other competing ring technologies. With the introduction of spatial reuse, MANs and LANs are at a greater advantage of maximizing bandwidth efficiency. Spatial reuse introduces the concept of congestion and Fairness Algorithms are needed to police the fair access of the low priority(More)
Resilient Packet Ring (RPR) is a new technology being standardized by the IEEE 802.17 working group. This paper presents a ring access delay bound under steady state. The bound is then proved analytically. Furthermore we show that the bound is tight by constructing a worst-case traffic scenario. It is shown that straight overloading scenarios are not the(More)
