Claim 11:
12. A method for rapid recovery of session failures in a communication network, the method comprising:
detecting, by an overwatch system, establishment of a communication session to effect end-to-end connectivity for one or more user devices on a communication network via participating network functions (NFs) of the communication network;
analyzing the communication session, by the overwatch system, to determine a critical session context dataset (CSCD) template that defines, for each NF of the participating NFs, a respective CSCD by which the NF uniquely defines the communication session;
capturing end-to-end context data for the communication session, by the overwatch system while the communication session is active, by continuously recording, from each NF of the participating NFs, the respective CSCD for the NF and respective endpoint information for the NF that indicates with which others of the participating NFs the NF is communicating to effect the communication session;
detecting a session failure causing at least a failed NF of the participating NFs to be reassigned to a replacement NF that is not previously one of the participating NFs; and
recovering the communication session, by the overwatch system responsive to the detecting the session failure, by providing at least the replacement NF with recovery data generated from the end-to-end context data.
