Methods, systems, and computer readable media for producer network function (NF) service instance wide egress rate limiting at service communication proxy (SCP)

Abstract:

Methods, systems, and computer readable media for network function (NF) service instance wide egress rate limiting include a process performed at a service communication proxy (SCP) and at a rate limiting policer. The process includes receiving service requests from consumer NFs and forwarding the service requests to SCP worker instances. The process further includes, at the SCP worker instances, requesting, from the rate limiting policer, which is separate from the SCP worker instances, producer NF service instance capacity for handling the service requests. The process includes, at the rate limiting policer, performing producer NF service instance wide egress rate limiting between the SCP worker instances and producer NF instances by granting or denying requests for producer NF service instance capacity from the SCP worker instances such that combined egress traffic from the SCP worker instances does not exceed rate capacities of the producer NF service instances.
