Abstract
A flow in a network is identified and handled by using a virtual host address. A packet is received at a switch with a first virtual host address as its destination address. If the packet is the first packet of a flow received by the switch, then a second virtual host address is determined by the switch. The first virtual host address is stored in a packet forwarding table correlated with the second virtual host address. A subsequently received packet of the same flow has the same first virtual host address as its destination address, and is forwarded to the second virtual host address in accordance with the packet forwarding table.
