Abstract:
1. A method of detecting reciprocating communications links between nodes of a communications network, comprising: using one or more sensors to detect communications events from the nodes and the origination time of each communications event; wherein a communications event is at least a portion of a communication from one node to another; using an event receiver unit to receive event data from the one or more sensors, the event data representing a number of communications events each communications event having an associated node identifier and origination time; using a time window generator to receive the event data, and for a given node, to count the communications events from other nodes within each of a number of time windows; wherein each time window begins with a communications event from the given node and ends at the duration of the time widow; and using a link detector to receive count data from the time window generator, and to use the counts to determine the probability that any other node is a reciprocating node in reciprocating communication with the given node; wherein the reciprocating communication is represented by a number of pairs of communication events of the reciprocating node and the given node, each pair occurring within a time less than the time window duration.
