Egress Throttle Lists is used to manage coordinated Egress Throttling across multiple diameter signaling routers by adding Egress Throttle Groups to an Egress Throttle List. ETLs have congestion level states similar to Egress Throttle Groups, but they span multiple diameter signaling routers.
For Coordinated Egress Throttling across Multiple diameter signalling routers, all of the Egress Throttle Groups that belong to an Egress Throttle List must belong to the same network.
