A computer implemented method for identifying an end-to-end path through a network from a source device (X) to a final destination device (Y). A monitor computer connected to the network identifies a first device (A) connected to the source device and transmits a query to the first device, the query including a destination identifier and requesting identification of an egress port for messages addressed to that destination. The monitor receives a result message identifying the egress port and uses this in combination with an accessible network topology to identify a second device (B) connected to the first. The monitor sends a query to the second device and receives a next result message identifying an egress port from the second device. A third device (C) is then identified and the process repeated until the path is identified. The per hop behavior in combination with the network topology allows for the direct computation of the path. The invention has application in network analysis. |
