An efficient timeout message management in ieee 1394 bridged serial bus network

The overtime information management method and system in universal serial bus connecting network comprises: the remote overtime value of asynchronous operating (a) is realized comprises multiple for storing of the port of the port local bus on specific target bus a remote overtime of the magnetic registry to the same network, the (b) is cut-out address the port local bus overtime response information, the (c) a step (b) intercepts an overtime response information of a, (d) a overtime response information transmission of the reducer (b) intercepts and original addressing node; (e) is port interception overtime request information, includes the the overtime value by the retrieval or computing operation one of an, (g) is an overtime and transmitting end transmission overtime value. The bus source and target bus capable of the middle bus connected; and bus is further intercept and storing the overtime value in which the overtime of each time actual contact target end. A device comprises a intercepting, search and a switching response information hardware.
