Direct Connection

The UMS Console establishes a connection to the UMS server. The UMS server then establishes a TLS tunnel to the device. 

The following figure illustrates the communication between the UMS Console, the UMS server and a device:

Over ICG

Both the UMS Server and the device have established a WebSocket connection to the ICG; this WebSocket is used for commands from the UMS and messages from the device. 

The UMS Console and the device establish a dedicated WebSocket for the secure terminal with the ICG.
