Abstract
A virtual network has virtual machines on physical devices connected to network interfaces each 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 deliver the data packet to the remote physical device having that forwarding address. Such encapsulation enables virtual machines on different physical devices to communicate transparently to the underlying forwarding network. Virtual networks can be created to suit their applications yet use or share existing forwarding networks, while protecting the forwarding network from interference by the virtual machines, and maintaining isolation between virtual machines.
