Abstract
Network load balancing may be performed in a cluster by deploying multicasting or replication. In particular, one or more multicast trees may be deployed within the cluster. Packets may be multicast towards the hosts over the multicast tree(s) to reach the hosts in a pool of hosts associated with a given Virtual Internet Protocol ('VIP') address. Packets may be filtered before the packets reach the hosts to ensure that each host only receives packets for the session the host is handling. The filtering may be performed at various levels of the multicast tree. Replication may be deployed instead of multicasting to realize the same network load balancing.
