A network monitor (20, 24a, 24b), for use in a network (10) comprised of a plurality of segments (12, 14a, 14b), each segment connected to at least one other segment (12, 14a, 14b) by a bridge (16) operating transparently to stations (21a, 25a, 25b) on the network (10), and for resolving the location of a station (21a, 25a, 25b) on the network (10), includes a primary resolver (34) for generating and sending a primary probe (122) to the station, a primary observer (47) for monitoring primary probes (122) and for generating and sending a primary observation report (128) in response to the primary probes (122), a first receiver (36) for receiving the primary observation reports (128), and a circuit (38), responsive to the received primary observation reports (128), for generating and sending secondary probe requests. The network monitor (20, 24a, 24b) also includes secondary resolvers (48) for receiving the secondary probe requests (110) and for generating and sending secondary probes (122) in response thereto, secondary observers (40) for monitoring secondary probes (122) and for generating and sending a secondary observation report (128) in response thereto, a second receiver (40) for receiving the secondary observation reports, a circuit (40) for creating and transmitting a summary (136) of the received secondary observation reports (128), a third receiver (42) for receiving the summaries (136), and a resolver (44) for determining the location of the station (21a, 25a, 25b) based on the primary observation reports (128) and the summaries (136). |
