System and method for extending private networks onto public infrastructure using supernets

摘要

Methods and systems for enabling communications between a first private network and a second private network configured from nodes in a public network. When communicating a packet from the first private network to the second private network, a computer receives a packet from a source node in the first private network. The computer then determines whether the packet is destined for the second private network. Thereafter, if the packet is destined for the second private network, the computer forwards the packet to a destination node in the second private network. When communicating a packet from the second private network to the first private network, a computer receives a packet from a source node in the second private network. The computer then determines whether the packet is destined for the second private network. Thereafter, if the packet is not destined for the second private network, the computer forwards the packet to a destination node in the first private network.
