Figure 7.1: CCO VPN service architecture
When CCO is enabled, OXO Connect establishes and maintains a permanent connection to the CCO
infrastructure (blue arrow).
To establish a VPN with the OXO Connect:
• The OXO Connectivity application sends a VPN connection request to the OXO Connect via the
Connection service (1)
• The OXO Connect establishes an outband VPN connection with the VPN gateway (2), and returns
its VPN IP address to the application (3)
• The applications (OMC, web-based tool) use the VPN connection to exchange data with the OXO
Connect (4)
