The invention relates to a computer implemented method of identifying in a network of interconnected devices a path through the network from a source device to a final destination device, the path comprising a connected sequence of devices, the method comprising at a monitor computer connected to the network: identifying a first device connected to the source device; transmitting a first query to the first device, the query including a destination identifier and requesting identification of an egress port for messages addressed to the destination identified by the destination identifier when the query is received at the first device; receiving a result message identifying the egress port and identifying the second device connected to the first device based on a network topology accessible by the monitor computer; and addressing a next query to the second device and receiving a next result message identifying an egress port from the second device; and identifying from the network topology a third device connected to the second device, wherein the path is identified to include the first, second and third devices. |
