The RP can interconnect with the Auto-Configuration Server (ACS) to implement management functions through the TR-069 service offered by the ACS.

Figure 3-6 shows the interconnection between the RP and the ACS.

Figure 3-6 Interconnecting with the ACS

On this network:

• The RP communicates with the TR-069 server through the TR-069 protocol.
• The HTTP server is used to upload and download configuration files and download upgrade files.
• The Simple Traversal of UDP through NAT (STUN) server implements traversal between private and public networks and delivers management over all devices on both networks.
• The RP can be deployed on a public or private network, while the ACS must be deployed on a public network.
  • If the RP is deployed on a public network, it can be managed by the ACS through the TR-069 protocol.
  • If the RP is deployed on a private network, the STUN server needs to be deployed for traversal between private and public networks. After the deployment, the TR-111 protocol, an extension of the TR-069 protocol, will be available for the ACS to manage the RP.
