LLAP
LocalTalk Link Access Protocol, the protocol spoken on a LocalTalk network. It has a "dynamic address-acquisition" method, which means new machines choose a random address and then ask the net if it's unique. If so, the machine adopts the address. If not, the machine chooses a new one and asks again. This permits a "plug-and-play" network.
