摘要

A method of determining a physical location of a client (104) in a data communication network, the method comprising:
- determining an identifier of a connection point (160) through which the client communicates with the data network; and
- determining a physical location of the client based on the determined identifier of the connection point, including accessing a stored association between the connection point identifier and the physical location;
wherein the connection point provides a communication path to the client via a cable-based transmission medium (12)
the method further comprising transmitting connection information from a network device in the data network to the client, and wherein determining the connection point identifier further comprises determining the connection point identifier using the connection information.
