Overview of the Evolving IEEE 802.17 Resilient Packet Rings Standard

چکیده
Abstract: We present an overview of the IEEE 802.17 Resilient Packet Ring (RPR) protocol standard for metropolitan area networks. We discuss the main characteristics of the protocol and the main drivers for its development. We outline various aspects of the protocol: architecture and operation principles, physical layer, packet formats, the MAC protocol and its fairness, protection switching and topology discovery. We also discuss possible ways and technologies that could be used by a carrier to evolve its services and network architecture to meet the everincreasing demand for bandwidth in the metropolitan area.

Congestion Domain Boundaries in Resilient Packet Rings
In June 2004, the IEEE approved a new standard for Resilient Packet Rings (RPR). The standard is maintained in the 802 LAN/MAN Standards Committee, and is designated the standard number 802.17. In this paper, we analyze and discuss performance aspects of the Resilient Packet Ring fairness mechanism. We explain that, if the ring is not configured correctly, the fairness mechanism fails to stabil...
متن کاملAchieving destination differentiation in ingress aggregated fairness for resilient packet rings by weighted destination based fair dropping
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 introduces destination differentiation in ingress aggregated fairness for RPR and focuses on the RPR MAC client implementation of the IEEE 802.17 RPR MAC in the aggressive mode of operation. It also introduces an enhan...

متن کاملInter-ring Traffic Management in Bridged Resilient Packet Rings: Global Fairness and Buffer Overflow Prevention
Resilient Packet Ring (RPR) is a dual-ring network, also known as the IEEE 802.17 Standard. As with other IEEE 802 networks, multiple RPR networks can be bridged together to form a bridged network when necessary. However, further research is necessary on additional issues that arise from bridging RPR networks. In this paper, we place emphasize on two of these issues; that is, fairness for inter...
متن کاملMulticasting in IEEE 802.17 resilient packet ring
By using destination stripping and shortest-path routing, the new standard IEEE 802.17 resilient packet ring (RPR) allows for spatial reuse, resulting in a significantly increased capacity compared to source-stripping legacy ring networks. We show that for multicast traffic the performance of RPR reduces to that of legacy ring networks that do not support spatial reuse. We propose a bandwidth-e...
