Abstract
Techniques are described for end-to-end overwatch of communication sessions in a network for fast failure recovery. At any time, network functions (NFs) can be supporting end-to-end connectivity for large numbers of concurrent active communication sessions. Conventionally, if one or more of the NFs fail, session context information can be irretrievably lost, and session connectivity is lost. Embodiments provide an overwatch system in an overwatch plane of the network to determine critical session context dataset (CSCDs) for NFs participating in active communication sessions, and to continuously take snapshots of the entire end-to-end context of active communication sessions in accordance with the CSCDs and endpoint information for the NFs. In the event of a session failure, embodiments generate recovery data from the recorded end-to-end context data, which can be used to rapidly restore full, end-to-end session connectivity, thereby maintaining the active communication session without a loss of session context.
