IEEE Standard for Information Technology – Telecommunications and Information Exchange Between Systems – Local and Metropolitan Area Networks – Specific Requirements – Part 17: Resilient Packet Ring (RPR) Access Method and Physical Layer Specifications – Amendment 1 – Spatially Aware Sublayer

IEEE 802.17b-2007 PDF
This standard defines 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.
802.17-2004 provides spatial reuse for ring-local unicast transmissions. This limits spatial reuse to host stations (e.g. routers) attached to the ring and precludes other devices that(eg. bridges). The amendment will extend the class of frame types and device types that can achieve spatial reuse to significantly improve bandwidth efficiency on Resilient Packet Rings.
Amendment Standard – Superseded. This amendment enables a service provider to use the architecture and protocols of IEEE Std 802.17TM-2004 to offer improvements in bandwidth utilization, by means of spatial reuse, for applications of RPR that involve bridging clients.
