Resilient Packet Ring
RPR is a MAC layer, ring-based protocol that combines the intelligence of IP routing and statistical multiplexing with the bandwidth efficiencies and resiliency of optical rings. RPR networks consist of two counter-rotating fiber rings that are fully utilized for transport at all times for superior fiber utilization, unlike SONET/SDH-based networks. RPR permits more efficient use of bandwidth using statistical multiplexing. RPR eliminates the need for manual provisioning, because the architecture lends itself to the implementation of automated provisioning. Moreover, there is no need for channel provisioning as each ring member can communicate with every other member based on the MAC address. RPR also protects existing investment ...
