• RPR-IEEE design strategies increase effective bandwidths beyond those of a broadcast ring:
–
–
–
–
–
RPR-IEEE fairness features ensure proper partitioning of opportunistic traffic:
•
–
–
–
RPR-IEEE plug-and-play automatic topology discovery and advertisement of station capabilities
•
allow systems to become operational without manual intervention.
RPR-IEEE multiple features support robust frame transmissions:

• RPR-IEEE non-supported features:

Per-service-quality flow-control protocols regulate traffic introduced by clients.
Class A allocated or guaranteed bandwidth has low circumference-independent jitter.
Class B allocated or guaranteed bandwidth has bounded circumference-dependent jitter. This
class allows for transmissions of excess information rate (EIR) bandwidths (with class C
properties).
Class C provides best-effort services.
Clockwise and counterclockwise transmissions can be concurrent.
Bandwidths can be reallocated on nonoverlapping segments.
Bandwidth reclamation. Unused bandwidths can be reclaimed by opportunistic services.
Spatial bandwidth reuse. Opportunistic bandwidths are reused on nonoverlapping segments.
Temporal bandwidth reuse. Unused opportunistic bandwidth can be consumed by others.
Weighted fairness allows a weighted fair access to available ring capacity.
Aggressive fairness is supported.
Single Choke Fairness Supports generation, termination, and processing of Single Choke
Fairness frames on both spans.
Service restoration time is less than 60 milliseconds after a station or link failure.
Queue and shaper specifications avoid frame loss in normal operation.
Fully distributed control architecture eliminates single points of failure.
Operations, administration, and maintenance support service provider environments.
EoMPLS is not supported.
IP forwarding is not supported.
Wrapping, the optional IEEE 802.17b protection scheme, is not supported. Steering, the
protection scheme mandated by the standard, is supported.
Layer 3 routing is not supported.
