UCARP is a portable implementation of the CARP protocol.
|
|
|
|
UCARP allows a couple of hosts to share common virtual IP
|
|
addresses in order to provide automatic failover. It is a
|
|
portable userland implementation of the secure and patent-free
|
|
Common Address Redundancy Protocol (CARP, OpenBSD's alternative
|
|
to the patents-bloated VRRP).
|
|
|
|
Strong points of the CARP protocol are: very low overhead,
|
|
cryptographically signed messages, interoperability between
|
|
different operating systems and no need for any dedicated extra
|
|
network link between redundant hosts.
