'''Resilient Packet Ring''' ('''RPR'''), as defined by [[IEEE]] standard '''802.17''', is a protocol designed for the transport of data traffic over [[optical fiber]] ring networks. The standard began development in November 2000<ref>{{cite web|url=http://www.ieee802.org/17/projects/P802_17/P802_17_PAR.pdf|title=IEEE-SA Standards Board Project Authorization Request (PAR) (2000-Rev 1)}}</ref> and has undergone several amendments since its initial standard was completed in June 2004. The amended standards are 802.17a through 802.17d, the last of which was adopted in May 2011.<ref>{{cite web|url=http://www.ieee802.org/17/|title=IEEE 802.17 Resilient Packet Ring Working Group}}</ref> It is designed to provide the [[resilience (network)|resilience]] found in [[SONET]] and [[Synchronous Digital Hierarchy]] networks (50&nbsp;ms protection) but, instead of setting up circuit oriented connections, provides a packet based transmission, in order to increase the efficiency of [[Ethernet]] and [[Internet Protocol|IP]] services.
