Abstract
A data switch for network communications includes a data port interface which supports at least one data port which transmits and receives data. The switch also includes a CPU interface, where the CPU interface is configured to communicate with a CPU, and a memory management unit, including a memory interface for communicating data from the data port interface to the switch memory. A communication channel is also provided, communicating data and messaging information between the data port interface, the CPU interface, the switch memory, and the memory management unit. The data port interface also includes an access control unit that filters the data coming into the data port interface and takes selective action on the data by applying a set of filter rules such that access to the switch is controlled by the set of filter rules.
