Location discovery in a data network
View Patent ↗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.
1. A method comprising:
receiving, at a first device, connection information from a neighboring network device;
determining a physical location of the first device based on the connection information;
receiving, at the first device, the physical location transmitted from the neighboring network device;
receiving, at the first device, a second physical location transmitted from a second neighboring network device; and
comparing the first physical location with the second physical location to determine a level of confidence of the determined physical location of the first device.
2. The method of claim 1 further comprising associating a level of trust with the physical location based on the neighboring network device.
3. The method of claim 1 wherein the first device belongs to a group consisting of a router, a switch, a network entry device, a firewall device, a gateway, a wireless access point, and a computing device.
4. A system comprising:
a location module to determine a physical location of a connection point and to transmit the physical location to a client device in communication with the connection point, the client device to receive the physical location from the physical location module;
a neighboring network device in communication with the client device, the neighboring network device including the physical location module; and
a second neighboring network device with a physical location module to determine a second physical location of the client device and transmit the second physical location to the client device,
wherein the network device receives the second physical location and compares the first physical location with the second physical location to determine a level of confidence of a physical location of the client device.
5. The system of claim 4 wherein a level of trust, based on the neighboring network device, is associated with the physical location.
6. The system of claim 4 wherein the client device comprises a router, a switch, a network entry device, a firewall device, or a gateway.
