RESILIENT PACKET RING TECHNOLOGY
Ajay K. Sharma · 2013
IEEE802.17 Resilient Packet Ring (RPR) is a promising new technology that was standardized to meet the needs of telecommunication network providers and enterprise data network. RPR allows substantial re-use of the valuable existing telecommunications infrastructure, while also allowing a greatly simplified means of aggregation packetized data from many customers into the provider’s access and metro networks. The RPR fairness protocol and algorithm insures fair medium access among an RPR‘s users. RPR also provides the high reliability that has become increasingly important for enterprise network us ers. This paper reviews the key aspects of RPR, including medium access control and its fairness mechanism, physical layer options, protection restoration options, and bridging and routing within and across an RPR.
