Abstract (en)

[origin: WO0031925A1] The present invention relates to a method and a system for determining the topology of a network of nodes that are interconnected via unidirectional connections. According to the invention, the existence of a network loop within said network is determined using message forwarding among said nodes, and, as a result, information related to the existence of said network loop is distributed to nodes within said network.
