IEEE 802.17-2004

Define a Resilient Packet Ring Access Protocol for use in Local, Metropolitan, and Wide Area Networks, along with appropriate Physical Layer specifications for transfer of data packets at rates scalable to multiple gigabits per second. The standard will define a very high-speed network protocol that is optimized for packet transmission in resilient ring topologies. Current standards are either optimized for TDM transport, or optimized for mesh topologies. There is no high-speed (greater than 1 billion bits per second) networking standard in existence, which is optimized for packet transmission in ring topologies. New IEEE Standard - Superseded. This standard defines the medium access control characteristics, physical layer interface methods and layer management parameters for the resilient packet ring (RPR) access method for ring topologies. A set of protocols for detecting and initializing the shared ring configuration, recovering from failures, and regulating fair access to the shared medium are also described. Specifications are provided for interface to a number of physical layers, supporting data rates up to 10 Gb/s. System considerations and management information base (MIB) specifications are also provided in this standard.
