Abstract

In order to monitor the traffic in a part of a network a switch or bridge (1) includes a processor and a store. The processor is arranged to sample the traffic on a random or pseudo-random basis in real time and store the results for analysis by a management entity. The whole of a packet (10) may be captured and stored by the sampling device or, for more specific monitoring, only a predetermined portion of the packet may be stored.
