Methods, systems, and computer readable media for diameter-peer-wide egress rate limiting at diameter relay agent (DRA)

Last updated:

Abstract:

Methods, systems, and computer readable media for Diameter-peer-wide egress rate limiting include a process performed at a Diameter relay agent (DRA) and at a rate limiting policer. The process includes receiving service requests from Diameter-based consumers and forwarding the service requests to DRA worker instances. The process further includes, at the DRA worker instances, requesting, from the rate limiting policer, which is separate from the DRA worker instances, Diameter peer capacity for handling the service requests. The process includes, at the rate limiting policer, performing Diameter-peer-wide egress rate limiting between the DRA worker instances and Diameter peer instances by granting or denying requests for Diameter peer capacity from the DRA worker instances such that combined egress traffic from the DRA worker instances does not exceed rate capacities of the Diameter peers.
