Marker tag for a logical network connection between two devices using a specific communications protocol.

From: Networks | Connections

Device-to-device communication is modeled using a connection with the following tags:

As a general principle if a device sits "higher" in the network architecture, then it should be tagged with device1Ref. For example given a connection between a server and area controller, then the server should be device1Ref and and the area controller should be device2Ref. In peer-to-peer networking, this distinction should not matter.
