Carp, it's a kind of fish :-)
The Common Address Redundancy Protocol, you could say is like RAID for your network hosts. You can have multiple hosts sharing a set of IP, let's say you've got a master MySQL server that replicates its data to a pair of slave servers, one for backup and one on hot standby to be swapped out with the master in the event of doomsday. Then all of a sudden your master servers disk eats itself, and you've only got the slave servers! With CARP, you should be able to have your network setup so the mysql slave server on hot standby takes over for the master, rather then making clients wait until you manually get her servicing the masters requests.
At least, that is how /I/ understand it.
