Overview of CWMP

Overview of CWMP

This section describes the definition, background, and functions of CWMP.

Definition

On a DSL network, device management is difficult because there are many user-side devices distributed at different locations. CWMP defines that the customer premises equipment (CPE) is remotely managed by an auto-configuration server (ACS). CWMP facilitates CPE management, reduces maintenance and operation costs, and improves troubleshooting efficiency.

CWMP, also called Technical Report 069 (TR-069), is a technical specification drafted by the Digital Subscriber's Line forum (DSL forum, which was later renamed as Broadband Forum).

Purpose

CWMP provides methods to manage and configure home network devices on the next generation network. Currently, terminal management faces the following problems:

  • Different vendors manage their terminals in different ways.

    Terminal vendors manage their terminals by using different protocols such as the Optical Network Terminal Management and Control Interface (OMCI) and Embedded Operations Channel (EOC) protocols. Carriers must integrate these vendors' network management systems multiple times to implement unified management.

  • Various terminals lead to complex terminal management.

    With emergence of new access technologies, various terminals are developed, such as access points (APs), optical network terminals (ONTs), and shared risk groups (SRGs), which are difficult to manage.

  • Troubleshooting is difficult because of a large number of terminals.

    On a network, most faults occur on the user side, where a large number of terminals are scattered; therefore, troubleshooting is difficult.

To solve the preceding problems, CWMP defines a mechanism to manage the CPE by an ACS. This facilitates CPE management, reduces maintenance and operation costs, and improves troubleshooting efficiency.
