CWMP mechanism

Auto-connection between the ACS and a CPE

When a CPE starts up for the first time, it automatically obtains an IP address from the DHCP server,
which informs the CPE of the following information:
• The URL address of the ACS (assigned by the DHCP server through Option 43)
• Username and password for connecting the ACS (assigned by the DHCP server through Option 43)
• DNS server address (directly assigned)
After the CPE receives the above information, it has the IP address of the ACS resolved by the DNS server,
and sends a connection request to the ACS. If the CPE passes the authentication with the acquired
username and password, the connection between the ACS and the CPE is established.
If the current session is not finished but the connection between ACS and CPE is interrupted, the CPE
automatically establishes a new connection with the ACS until the number of CPE auto-connection retries
reaches the limit.
The CPE can send connection requests either periodically or at the specified time to the ACS. The ACS
can initiate a connection request to the CPE at any time, and can establish a connection with the CPE
after passing CPE authentication.
