ROUTER SYSTEM INTERFACE DEVICE

摘要

PURPOSE: A router system interface device is provided to easily compose a line interface device because it is unnecessary to use a separate PCI(Peripheral Component Interconnect) bridge by using a processor having an interface function as a line processor. CONSTITUTION: A network processor(402) analyzes a received packet, and forwards the packet. A line processor(403) communicates with the network processor(402) by an embedded PCI function, and provides routing information to the network processor(402). A physical layer matching unit(401) connects with a certain external communication device, transmits and receives a signal with the communication device according to a certain protocol, and provides the received signal to the network processor(402) or the line processor(403). A switch interface unit(409) connects the network processor(402) with the line processor(403) through a back-plane. A device control matching function unit(410) initializes the network processor(402) and the line processor(403).
