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.
