protocol is a connection establishment between the source computer to destination computer
ex: tcp / ip protocol
File Transfer Protocol.
A transaction that follows the 2PL protocol can be divided in to 2 phases. * Expanding phase-new lock on items can acquire but NONE can be released * shrinking phase-existing locks can be released but no new locks can acquire 2 Phase Lock may limit the amount of concurrency that can occur in a schedule.
Darn it i figured out one solution. Send the computer a java applet that somehow figures out the computer's LAN IP address and then connects to my server and reports back with the ip address. Seems a little too complicated, but here's one implementation: http://ip-lookup.net/index.php that's what i want. But are there any simpler solutions ? like maybe theres already a potocol for doing this or maybe idk something easier...
