GGSN. It is instantiated when an MBMS policy CLI is configured in the GGSN
Service configuration mode. dgmbmgr
Maintains the MBMS UE and bearer contexts.
Handles the Gmb interface over a Diameter connection to a BMSC Server for MBMS
bearer sessions. dgmbmgr recovers by polling all sessmgrs for MBMS session states
and recreating the MBMS UE and MBMS bearer context information.

diamproxy
Diameter Proxy
Created by diactrl (which runs as part of vpnctrl) and the number of diamproxy tasks
spawned is based on the configuration to use “multiple” or “single” proxies. In
instances that a single proxy is configured, only one diamproxy task is spawned for
the entire chassis and runs on demux packet processing cards. When multiple proxies
are configured, one diamproxy task is run per packet processing card.

are configured, one diamproxy task is run per packet processing card.
Maintains Diameter base connections to all peers configured in the system.
Informs applications about any change in the connection status.
Acts as a pass-through to the messages from application to the Diameter server.
Just acts as a forwarding agent (does not maintain any queues).
A single Diameter proxy is used to service multiple Diameter applications.
