1. A system for aggregating information for an information consumer in a packet-switched digital network comprising:
- one or more filtering nodes attached to a network device on the digital network, each filtering node having a first port connected to a network line, a second port connected to the network device, and a third port for communicating filtered information flowing between the first port and the second port to an aggregation node, an aggregation node having a first port for communicating with one or more filtering nodes, the aggregation node aggregating the filtered information and passing the aggregated information to an information consumer on a second port.

Abstract
Port mirroring with filtering of information on a digital network. By replacing standard interface modules on router or switch ports with modules containing filtering hardware and a wireless link to an aggregation module, traffic of interest may be monitored. The combination of filtering on each monitored port, and communicating wirelessly with the aggregation node reduces the volume of information which must be handled, and separates it from normal network traffic.

14. A filtering node for use on a port of a packet-switched digital networking device, the filtering node comprising:
-
a first port for communicating with the packet-switched digital network, a second port for communicating with the digital networking device, communications means for passing information between the first port and the second port, filtering means connected to the communications means for filtering information passing between the first port and the second port and passing the filtered information to a third port. - View Dependent Claims (15, 16, 17, 18, 19, 20)
