9 TR-069 CWMP Based Management
The device supports TR-069 CPE WAN Management Protocol (CWMP) based
management, which is used for remote management of CPE devices. This allows the
device to be configured and monitored from a management application running on a
remote Auto-Configuration Server (ACS).
9.1 TR-069
TR-069 (Technical Report 069) is a specification published by Broadband Forum
(www.broadband-forum.org) entitled CPE WAN management protocol (CWMP). It defines
an application layer protocol for remote management of end-user devices.
TR-069 uses a bi-directional SOAP/HTTP protocol for communication between the
customer premises equipment (CPE) and the Auto Configuration Servers (ACS). The TR-
069 connection to the ACS can be done on the LAN or WAN interface.
The protocol stack looks as follows:
TR-069 Protocol Stack
CPE/ACS Management Application
RPC Methods
SOAP
HTTP
SSL/TLS
TCP/IP
Communication is typically established by the CPE; hence, messages from CPE to ACS
are typically carried in HTTP requests, and messages from ACS to CPE in HTTP
responses.
