SYSTEM AND METHOD FOR ASSOCIATING A DLPDU RECEIVED BY AN INTERFACE CHIP WITH A DATA MEASUREMENT MADE BY AN EXTERNAL CIRCUIT

摘要

A diagnostic tool (20) has a packet based network medium attachment unit (22), a measurement interface (26), a network interface (28), and a microprocessor (30) for reading DLPDUs from a network segment and for taking simultaneous measurements of DLPDUs on the segment. The measurement data is associated with a stored DLPDU if the DLPDU is still active on the network segment when the measurement data is read by the microprocessor (30). The diagnostic tool (20) utilizes a currently active attribute to determine the status of a DLPDU.
