CWMP (TR-069) configuration
CWMP (TR-069) overview
CPE WAN Management Protocol (CWMP), also called "TR-069," is a DSL Forum technical specification
for remote management of home network devices. It defines the general framework, message format,
management method, and data model for managing and configuring home network devices.
CWMP applies mainly to DSL access networks, which are hard to manage because end-user devices are
dispersed and large in number. CWMP makes the management easier by using an autoconfiguration
server to perform remote centralized management of customer premises equipment.
CWMP network framework
Figure 21 shows a basic CWMP network framework.
Figure 21 Network diagram
The basic CWMP network elements include:
• ACS—Autoconfiguration server. An ACS delivers configurations to CPEs and provides management
services to CPEs.
• CPE—Managed device in the network. A CPE reports its information to the ACS and obtains
configurations from the ACS.
• DNS server—An ACS and a CPE use URLs to identify and access each other. DNS is used to resolve
the URLs.
• DHCP server—Assigns IP addresses to CPEs, and uses the options filed in the DHCP packet to issue
configuration parameters to the CPE.
Your device can work as the CPE but not the ACS.
