Telephones of the Internet Age

So, you want to ring that long lost uncle twice removed on you father's side. What do you do? Pick up the phone and call him, talk, listen, and finally hang-up. The same is true in GAT. If one process wants to contact a second process, it goes through the exact same steps. Simple. GAT tries to make things as simple as possible, but no simpler. After all, what could be simpler than using one of these?

• Calling
• Speaking and Listening
• Hanging-Up
