Abstract
A network data monitoring device provides for the flexible, programmable port-to-multi-port steering of data packet traffic between network port pairs, with tap data streams being directed to any of a plurality of monitor ports. The network data monitoring device is constructed utilizing one or more switching integrated circuits programmed to disable layer-2 routing and impose port-to-multiport data packet steering. Physical layer protocol encoding/decoding circuits enable connectivity to physical network media connectors though a system of fail-safe relays. A system controller, preferably implemented by a microprocessor, is connected to all switching integrated circuits and relays for configuration, status and control. Hardware-based logic selectively in complement to the switching integrated circuits provides for the programmable filtering, modification and programmable steering of data packets through the device.
