Generic Call Flow

This section describes the generic call flow for the Cisco AR 3.5 prepaid billing solution. The call flow is controlled by the AAA client. The Cisco AR 3.5 server converts VSAs into calls to the billing server. The packet flows presented in Figure 6-1are specific to the Cisco AR 3.5 prepaid billing solution only. The headlines in the packet flows are general and do represent all data transferred. The letters c, s, and b in Figure 6-1designate the packet’s source of client, server, or billing server, respectively.
