ABSTRACT:
A method for location discovery in a data network includes receiving, at a first device, connection information from a neighboring network device and determining a physical location of the first device based on the connection information. The method can include receiving, at the first device, the physical location transmitted from the neighboring network device. The method can further include associating a level of trust with the physical location based on the neighboring network device. The first device be one of a variety of devices, such as a router, a switch, a network entry device, a firewall device, or a gateway.
