CWMP network framework

Figure 57 shows a basic CWMP network framework.

A basic CWMP network includes the following network elements:

• ACS—Autoconfiguration server, the management device in the network.

• CPE—Customer premises equipment, the managed device in the network.

• DNS server—Domain name system server. CWMP defines that the ACS and the CPE use URLs to identify and access each other. DNS is used to resolve the URLs.

• DHCP server—Assigns ACS attributes along with IP addresses to CPEs when the CPEs are powered on. DHCP server is optional in CWMP. With a DHCP server, you do not need to configure ACS attributes manually on each CPE. The CPEs contact the ACS automatically when they are powered on for the first time.

The device is operating as a CPE in the CWMP framework.
