ABSTRACT:
A method is provided for ascertaining topology features of a network comprising a plurality of sub-networks, spanning devices interconnecting the sub-networks, and stations operative to source and/or sink traffic to/from the sub-networks. The traffic is in the form of discrete message packets each including source and destination information. Traffic on each of the sub-networks is monitored by a respective monitoring device and a partial traffic matrix is built up for each sub-network. These partial traffic matrices are then analyzed by a central processing station to determine, for example, the association of stations within the with sub-networks, and the interconnection of sub-networks by spanning devices.
