CWMP mechanism

RPC methods

CWMP provides the following major remote procedure call methods for an ACS to manage or monitor

a CPE:

• Get—The ACS gets the value of one or more parameters from the CPE.

• Set—The ACS sets the value of one or more parameters on the CPE.

• Inform—The CPE sends an Inform message to an ACS whenever the CPE initiates a connection to

the ACS, or the CPE's underlying configuration changes, or the CPE periodically sends its local

information to the ACS.

• Download—The ACS requires a CPE to download a specific file from the specified URL, ensuring

upgrading of CPE software and auto download of the vendor configuration file.

• Upload—The ACS requires a CPE to upload a specific file to the specified location.

• Reboot—The ACS remotely reboots the CPE when the CPE encounters a failure or completes a

software upgrade.

How CWMP works

The following example illustrates how CWMP works. Suppose there are two ACSs in an area: main and

backup. The main ACS needs to restart for a system upgrade. To ensure a continuous monitoring of the

CPE, the main ACS needs to let all CPEs in the area connect to the backup ACS.
