Introduction

IEEE 802.1CB “Frame Replication and Elimination for Reliability” is one of the TSN (Time Sensitive Networking) standards developed by the 802.1 working group. Using Frame Replication and Elimination for Reliability (FRER) within a network increases the probability that a given packet will be delivered using multi-paths through the network.

The GMAC 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.
