When creating a request, the End-to-End Identifier is set to a locally unique value. Depending on the Auth-Request-Type AVP, the Diameter protocol allows authorization-only requests that contain no authentication information from the client.

Network Working Group P. If authorization was requested, ciameter successful response will include the authorization AVPs appropriate for the service being provided, as defined in section 6.
