Abstract
A virtual network has network interfaces coupled by tunnels () through a forwarding network (), each interface having a forwarding address in an address space of the forwarding network, each network interface having a reconfigurable address mapper () for determining a forwarding address for a packet, and encapsulating the packet with its forwarding address so that the forwarding network can forward the data packet transparent to its destination address. The network interface automatically configures the address mapper by sending a discovery request for a given virtual network address over the forwarding network, to prompt a response with an indication of the corresponding forwarding address, and to use the indication in such a response to configure the address mapper. This can ease the administrative burden of setting up and maintaining the address mapper and to ease network reconfiguration according to demand or faults for example.
