Floating/Virtual IPs are one networking solution for HA. With Corosync/Pacemaker a cluster of hosts can decide how the ips are then assigned to physical hosts. CARP maybe/probably can do the same. I just googled and apparently there is also some IPVS/LVS project for Linux for HA loadbalancing?
VRRP, philosophically,
must ipso facto standard be
But standard it
needs to be free
vis-à-vis
the IETF
you see?
But can VRRP
be said to be
or not to be
a standard, see,
when VRRP can not be free,
due to some Cisco patentry..
