There is growing interest in resilient packet ring (RPR) as a technology to extend the capability of SONET/SDH access networks for packet data access. The RPR protocol is currently under development in IEEE 802.17 with the initial version of the standard recently published. The essential concepts of RPR are described in this white paper.
