Answer / ram

An address that can be used send by message same host
address but in different net work address that address can
be refered as multicastcast address.
Multicast address range:224.0.0.0 to 239.255.255.255
for example there are 5 managed servers in aclusters the
each managed server will communicate with the help of multi
cast address.after every 10 seconds heart beat checks
another are live or not if it is live it says i am live or
else no response. then the conclusion is that perticular
managed server is not live.
