Question

What's the best way to represent a networked connection in a UML class diagram?

Answer 1

UML class diagrams are not appropriate to describe a topological notion as a "network"; they are better suited for hierarchies and interdependencies between objects. Or are you talking about a Connection class?

Answer 2

The Class Diagram is the wrong place to be trying to show network connections. A Class diagram will show only the classes in your software and how they relate to each other. You should use a Deployment Diagram to show how the elements of your software are going deployed across the network.

You could also include a Communication Diagram to show how the different parts of the software communicate with each other without regard to the deployment model.
