Project: Broadband Access Center – CISCO Systems

The Cisco Broadband Access Center (BAC) software creates high volumes of provisioning data. BAC provides tools that enable you to distribute this data transparently across multiple databases and to backup important network and subscriber data.

When a device boots, it requests a configuration from BAC and it is this configuration that determines the level of service for the device.

During this process, the DHCP server requests the RDU to build a configuration for the device. The RDU generates a configuration and forwards it to all the DPEs that service the provisioning group that the device belongs to. The DPEs can now provide the device with its configuration without going to the RDU.
