ABSTRACT:
A router for interconnecting N interfacing peripheral devices. The router comprises a switch fabric and routing nodes coupled to the switch fabric. Each routing node comprises: i) a plurality of physical medium device (PMD) modules for transmitting data packets to and receiving data packets from selected ones of the N interfacing peripheral devices; ii) an input-output processing (IOP) module coupled to the PMD modules and the switch fabric for routing the data packets between the PMD modules and the switch fabric and between the PMD modules; and iii) a classification module associated with the IOP module for classifying a first data packet received from the IOP module. The classification module causes the IOP module to forward the first data packet based on the classification. The router architecture incorporates streams-based billing support, firewall capabilities, and data surveillance functionality.
