OpenBSD's Common Address Redundancy Protocol

Jessie writes "OpenBSD just gained high availability functionality in the form of a new protocol named CARP, the Common Address Redundancy Protocol. This feature was a long time in the coming due to Cisco's patent on VRRP, requiring the development of something completely new and more secure. This article on KernelTrap offers details on OpenBSD's impressive new protocol, from how it works to how it got its name."

Alternate name

My favorite part:

I suggested a different name (same four letters, different order, took a cheap shot at Cisco in the process), but Ryan didn't seem to care for it for some reason. 8)

BTW, the kerneltrap article renders perfectly in IE, but not Mozilla 1.4?!

Probably because Xerox has a trademark on PARC. Oh, wow, I just got a 35-year old joke.

Please RFC this

I understand that Theo and friends are pissed off by the IETF, but I really hope that they write an RFC for carp, so that we can have a compatible version for other OSes. Are there any detailed descriptions of CARP on the net yet ?

absolutely. Get this into freebsd and linux, and we'd have a true winner on our hands. Yet another killer feature that would allow bsd and linux to continue to take over the enterprise
