Overview

Metropolitan area networks (MANs) and enterprise networks typically use the ring topology to improve
reliability. However, services will be interrupted if any node in the ring network fails. A ring network
typically uses RPR or Ethernet rings. RPR is high in cost because it needs dedicated hardware. In contrast,
the Ethernet ring technology is more mature and economical, so it is more and more popular in MANs
and enterprise networks.
The Rapid Ring Protection Protocol (RRPP) is a link layer protocol designed for Ethernet rings. RRPP can
prevent broadcast storms caused by data loops when an Ethernet ring is healthy. RRPP can also rapidly
restore the communication paths between the nodes when a link is disconnected on the ring. The
convergence time of RRPP is independent of the number of nodes in the Ethernet ring. RRPP is applicable
to large-diameter networks.
