Systems and methods for packet or frame replication and elimination in a Time Sensitive Networking (TSN) network or Deterministic Networking (DetNet) network are disclosed. In some embodiments, a method of operation of a node in a TSN network or DetNet network comprises determining whether to reset a sequence recovery function used for frame or packet elimination for a particular stream of packets based on either or both of an explicit indication or an implicit indication and resetting the sequence recovery function used for frame or packet elimination for the particular stream of packets upon determining to reset the sequence recovery function. In this manner, packet or frame elimination is improved by avoiding scenarios that result in discarding valid packets or frames due to an out of sync condition between the sequence generation function at the replicator and the sequence recovery function at the eliminator.
