RFC – Diameter Network Access Server Application
This is achieved by including the RADIUS attribute space to eliminate the need to perform many attribute translations. The name is a play on words, derived from the RADIUS protocol, which is the predecessor a diameter is twice the radius.
Standards Track Cisco Systems Inc. When combined with the Diameter Base protocol, Transport Profile, and Extensible Authentication Protocol specifications, this application specification satisfies typical network access services requirements.
Adding a new optional AVP does not require a new diametwr. The Diameter protocol requires that relaying and proxying agents maintain transaction state, which is used for failover purposes.
It is set when resending requests not yet acknowledged as an indication of a possible duplicate due to a link failure. Diameter Network Access Server Application.
Received answers that do not match a known Hop-by-Hop Identifier are ignored by the Diameter agent. It is possible for tfc single session to be authorized first and then for an authentication request to follow. Retrieved from ” https: You can help by adding to it. This capability goes beyond the Call Check capabilities described in section 5.

If an AVP with the ” M ” bit set is received by a Diameter client, server, diametre, or translation agent and either the AVP or its value is unrecognized, the message must be rejected.
