Operating within an environment that incorporates technologies based on Multiprotocol Label Switching (MPLS) and the Label Distribution Protocol (LDP) to provide an ultra-reliable wireless backhaul service supporting large Internet of Things (IoT) and Industrial IoT (IIoT) environments (comprising, for example, many hundreds of radio devices), techniques are presented herein that support a mechanism to implement quality-perceived multiple label-switched paths (LSP)s that can perform replication according to path quality. Aspects of the presented techniques leverage a replication strategy, that is defined on both a client and a Network Appliance that defines how replication should be performed with preconditions, replication should be stopped when the preconditions are not met, or replication should be recovered when a precondition is met. According to aspects of the presented techniques, when a strategic precondition is met or not met, the corresponding LSP state is changed to "pending" or "recovered" (respectively) instead of being torn down or being rebuilt.
