GEOLOCATION MAPPING OF NETWORK DEVICES |
摘要 |
A geographic location of a network device is determined using response delay times from internet servers used as landmarks. A coordination server provides to a client a list of area landmark servers (ALS) with known geographic locations. The client probes ALSs, measures response delays, and provides results to the coordination server. The coordination server then provides to the client a list of additional city landmark servers (CLS) within the area. The client probes the CLSs and provides results to the coordination server which then determines the geographic location of the client. |
