802.1CB - Frame Replication and Elimination for Reliability
The full title of this PAR is "Standard for Local and Metropolitan Area Networks-Frame Replication and Elimination for Reliability".
This standard specifies procedures,
managed objects and protocols for bridges and end stations that provide:
- Identification and replication of frames, for redundant transmission.
- Identification of duplicate frames.
- Elimination of duplicate frames.
There are no other 802-compatible solutions providing fault tolerance without failover. To achieve
this, it is necessary to create and eliminate duplicate frames. This can be done in end stations and bridges.
