ABSTRACT:
A network switch for network communications includes at least one data port interface supporting a plurality of data ports transmitting and receiving data. A CPU interface is configured to communicate with a CPU, and an internal memory communicates with the at least one data port interface. A memory management unit is provided for communicating data from at least one data port interface and the memory. A communication channel is provided, for communicating data and messaging information between the at least one data port interface, the memory, and the memory management unit. The configuration of the network switch also includes a fast filtering process, with the fast filtering processor filtering packets coming into the at least one data port interface. Selective filter action is taken based upon a filtering result.
