Use Case – Multicast (2/2) Accounting Option 1: AN keeps track of when replication starts or stops, generates the time and/or volume accounting information and sends it to a central accounting system (no ANCP required) Option 2: AN keeps track of when replication starts or stops and reports this to the NAS for further processing Information Report Termination NAS can dynamically stop the replication of a multicast flow NAS sends “Admission Response” to AN to terminate replication |
