Gossiper in Cassandra using unicast/broadcast/multicast ?

Hi

   We are considering using Cassandra in virtualization environment. I
wonder is Cassandra using unicast/broadcast/multicast for node discover or
communication?

  From the code, I find the broadcast address is used for heartbeat in
Gossiper.java, but I don't know how actually it works when node
communication and when node start up (not for new node added in)

BRs

Cassandra works very well in EC2 environment. EC2 doesn't support
broadcast/multicast. So, you should be fine.

Thank you,
  Andrey
