Method and apparatus for monitoring a network

Method and apparatus for monitoring a network

Disclosed is a system (100, 204) that monitors the signal strength of each transmission by a node on a LAN cable (118) of a local area network and determines the location of the node sending the signal. This system has a monitor (112, 204) at each end of the LAN cable (118), with one of the monitors...

description Disclosed is a system (100, 204) that monitors the signal strength of each transmission by a node on a LAN cable (118) of a local area network and determines the location of the node sending the signal. This system has a monitor (112, 204) at each end of the LAN cable (118), with one of the monitors typically being located in a computer node (100) attached to the cable (118). When an information frame (302) is sent on the cable (118), each of the monitors (112, 204) records the signal strength of the frame preamble (304) and the source address (310) contained within the frame (302). The distance to the node from a first end of the cable, expressed as a percentage of the length of the cable, is the ratio of the signal strength at the second end of the cable to the sum of the signal strengths.
