I have a desktop application that serves as a smart, software-based router. Each of multiple nodes in the GUI can be either a UDP or TCP connection. We have the following status icons for the node:
TCP Connected: Green arrow
TCP Not Connected: Yellow warning icon
UDP: <Same as TCP working>
Customer has asked for a different icon set to distinguish UDP and TCP connections just for the information. We also have an internal usability concern that a green arrow for a UDP connection gives a false sense of it working (i.e. - the data being received on the other end).
We would like to add a third icon for the UDP connection, but have not been able to find a common standard for what they should look like. Is there any standard? If not, does anyone have any ideas?
Edit/Additional Info:
There is already a small text description on the node that says UDP/TCP as well as Server/Client, an IP port, the node name. The problem is that there may be dozens of ports, so we have some icons for important, at-a-glance information. This includes the connection status, logger status, a filter indicator, and an indication when a node shares a socket connection with another node.
