?– Efficient allocation of protection bandwidth RPR allows flexible allocation
of protection bandwidth on a per service basis. This allows a carrier to provision
protection for the committed-rate portion of any service.
?– Fairness The RPR MAC guarantees fair distribution of bandwidth across the
ring. While Connection Admission Control (CAC) mechanisms guarantee that
high-priority traffic is delivered with the appropriate SLA, the RPR fairness algorithm
dynamically allocates free bandwidth in a fair manner to all excess and best
effort traffic over the shared ring.

Complete Transparency to End-user Traffic RPR can carry all services transparently,
without any manipulation of end-user traffic. All end-user control traffic is also
carried transparently, and all traffic management is done on a per-CoS basis, in a manner
transparent to specific end-user traffic.
Support for Ethernet-based E-Line & E-LAN Services for Business Users RPR supports
the full range of Ethernet-based E-Line and E-LAN services and for metro networks
it is an efficient solution for Ethernet-based traffic from business users.
