Abstract
A network diagnostic tool for determining the position of a workstation on a local area network (LAN) having timer and echo stations at each end of a multi-access bus. Signals from the LAN workstations propagate in both directions along the bus. When the signals are so propagated, by measuring the time delay between receipt of a data packet and its echo at the timer station, the position of the workstation along a bus can be determined in accordance with that time delay.
