4.5.3.2.2 The Accounting-Answer (ACA)
The Accounting-Answer (ACA) command, indicated by the Command-Code field set to 271 and the
Command Flags' 'R' bit cleared, is used to acknowledge an Accounting-Request command. The
Accounting-Answer command contains the same Session-Id and MAY contains the same Accounting
Description and Usage AVPs that were sent in the Accounting-Request command. If the CMS-Data AVP
was present in the Accounting-Request, the corresponding ACA message MUST include the CMS-Data
AVP signed by the responder to provide strong AVP authentication, which MAY be used for the purposes
of repudiation.
Only the target Diameter Server, known as the home Diameter Server, SHOULD respond with the
Accounting-Answer command.
