1. A method, comprising:
obtaining, by a first network function of a core network, a session retention indicator for a protocol data unit (PDU) session;
calculating, by the first network function, a compute footprint for the first network function to support the PDU session and any other premium sessions currently serviced by the first network function;
forwarding, to an orchestration device, the compute footprint;
provisioning, by the orchestration device, a second network function based on the compute footprint; and
performing replication, of session state data for the PDU session, between the first network function and the second network function.
