Abstract: PURPOSE: A line interface module in a router and a routing system having the same are provided to integrate many line interfaces into a single line interface module and to execute fault management, inter-processor connection, switch interfacing, etc., through the line interface module. CONSTITUTION: A line interface module(10) consists of a sub switching card(13) and a backplane(14). The sub switching card(13) comprises line cards(11,12), a sub switch(131), and switch input-output buffers(133,134). The backplane(14) connects between the line cards(11,12) and the sub switching card(13). Each line card(11,12) comprises physical link ports(111,114,121,124), physical layer interface parts(112,15,122,125), and network processors(113,116,123,126). The network processors(113,116,123,126) process the packet switching and forwarding function of an OSI(Open System Interconnection) 3/4+ layer. The sub switch(131) executes sub switching to target data channels for the data supplied from the line cards(11,12) and the switch input-output buffers(133,134). The switch input-output buffers(133,134) buffer the data inputted/outputted between the switch of a routing system and the sub switch(131).

Abstract: PURPOSE: An apparatus and a method for exchanging an IPC(Inter Processor Communication) message using an ethernet switching device are provided to install the ethernet switching device in a module matching backplane of an ATM(Asynchronous Transfer Mode) switch, construct an IPC message dedicated star ethernet network, and transmit and receive the IPC message using an ethernet switching method. CONSTITUTION: An ethernet switching device(112) switches a path of an IPC ethernet frame transmitted from a transmission side processor and transmits the IPC ethernet frame to a receipt side processor. Each processor connects to a star ethernet network centering around the ethernet switching device(112). The ethernet switching device(112) is embedded in a main processor module(110).
