IEEE 802.1CB “Frame Replication and Elimination for Reliability” is one of the Time Sensitive Networking (TSN) standards. Using Frame Replication and Elimination for Reliability (FRER) within a network increases the probability that a given packet is delivered using multi-path paths through the network.
The MAC supports a subset of this standard and provides the capability for stream identification and frame elimination but does not provide support for the replication of frames.
