Abstract: PURPOSE: A packet forwarding device for expanding connection resources is provided to enable an LSP(Label Switching Path) requested by an MPLS(Multi Protocol Label Switching) unit by using VPI/VCI connector information used in an ATM, thereby supporting an MPLS function in an ATM-based IP forwarding engine. CONSTITUTION: A physical layer interface(201) generates an AAL5 ATM cell-base packet from a data stream received from a client. A reception ATM cell reassembling portion(202) generates a reassemble packet. A lookup controller(203) looks up an output link path of the reassemble packet in reference to information on the reassemble packet, and generates an expanded tag adding packet that adds an expanded tag to the reassemble packet in order to expand connection resource capacities of an output link. A reception ATM cell segment portion(208) segments the adding packet into ATM cells. An ATM switch interface(205) inserts routing tag information into the ATM cells so as to search a switching path of the ATM cells.

Abstract: PURPOSE: A method for duplicating an IPC(Inter-Processor Communication) channel using Ethernet hub boards is provided to stabilize an IPC channel by using two duplicated Ethernet hub boards. CONSTITUTION: If an IPC message to be transmitted to processor B or C(130,140) is made at processor board A(120) in the form of an Ethernet frame, the made Ethernet frame is transferred to processor B or C(130,140) through an active Ethernet hub board among two duplicated Ethernet hub boards A and B(100,110) according to an Ethernet protocol operation. On the contrary, on case that an IPC message to be transmitted to processor A(120) is made at processor board B(130) in the form of an Ethernet frame, the made Ethernet frame is transferred to processor A(120) through the active Ethernet hub board according to an Ethernet protocol operation.

Abstract: PURPOSE: An OAM(Operating And Management) processing method in an ATM(Asynchronous Transfer Mode)-based MPLS(Multi Protocol Label Switch) system is provided to offer an OAM function requested between a router and a subscriber network and offer an OAM function with respect to an ATM service in the ATM-based MPLS system. CONSTITUTION: Channel information set up through an IPC(Inter Processor Communication) between an FE(Forwarding Engine)(31) and an MSC(MPLS Service Controller)(34) is stored in a table. A service type is judged from the formed channel table whenever an OAM cell is inputted to a specific channel. If the received OAM cell is an OAM cell inputted to an LSP(Label Switched Path) channel, the OAM cell is transmitted to the FE(31) through a PCI(Peripheral Component Interconnect). If the received OAM cell is an OAM cell inputted to an ATM channel, the OAM cell is transmitted to an input and output buffer switch(32) through a UTOPIA(Universal Test and Operations PHY Interface for ATM). The OAM process with respect to the LSP channel and the ATM channel is simultaneously performed in one system. Various OAM function are embodied between the FE(31) and a node of a subscriber network through the IPC from the MSC(34).
