Abstract: PURPOSE: A method of automatically recognizing network node shape management information by using an SNMP(Simple Network Management Protocol) is provided to automatically recognize the shape management information of a recognized network management target node by using the SNMP, and to connect the information with the target node, thereby easily performing a shape management function. CONSTITUTION: A network management system stores shape management information of a network management target node in a storage(S201). When the target node is recognized(S202), the system decides whether the target node supports an SNMP(S203). If so, the system inquires of the target node about system object ID management information(S204). The target node responses to the inquiry based on the SNMP, and the system receives the response(S205). The system decides whether the shape management information exists in the storage(S206). If so, the system includes the information in management information of the target node(S208). If a manager requests the shape management information to be updated(S209), the system updates the shape management information(S207).

Abstract: PURPOSE: A BIPC(Bridging Inter Process Communication) processing method for BPDU(Bridging Protocol Data Unit) transceiving in a router/bridge system is provided to enable a BPDU transceiving between one main processor and plural line cards, thereby processing an L2 BPDU in a router/bridge system. CONSTITUTION: An L2 application protocol opens a socket, and binds a virtual device mapped with an outer interface one to one by using the socket(S401,S402). If the L2 application protocol transmits BPDU data to the self socket, a kernel receives the BPDU data through the virtual device(S403), and generates a perfect BPDU frame by adding a BPDU header(S404). The L2 application protocol searches a slot and a port mapped with the virtual device and a destination MAC address of a line card(S405), and adds a BIPC header to the BPDU frame(S406). The BIPC frame is transmitted to the line card(S407).

A voter(400) outputs the final result value according to a majority voting rule algorithm(420) discriminating the component occurring the value failure by respectively receiving a process result value for the same input from the three components. The component receiving a restart order from the voter performs the initialization for each configuration element.

Abstract: PURPOSE: A 2-layer multicast group managing method using IGMP packet information in an ethernet switch is provided to allow hosts, which do not support GMRP or GVRP, to register a desired 2-layer multicast group and virtual LAN by using an IGMP packet of an IP layer. CONSTITUTION: An ethernet switch makes an MAC look-up with a destination MAC address of a frame received from a port set in an access mode or in a hybrid mode(601,602). The ethernet switch determines whether a range of the destination MAC address corresponds to 01:00:5e:00:00:00-01:00:5e:7f:ff:ff(603). If it is determined to be an IGMP packet, the ethernet switch searches a mapped virtual LAN ID by searching a mapping table with the group address in the IGMP packet(605-607). It is determined whether a type field value in the IGMP packet relates to a group registration request or deletion(608). If the field value relates to the registration request, the ethernet switch generates a virtual LAN table entry(609,610).

Abstract: PURPOSE: A method for linking MPLS network of MPOA network and ATM-based is provided to omit an IP(Internet Protocol) address look-up and connect MPOA and MPLS networks without joint when MPOA(Multi-Protocol Over ATM) network and ATM-based MPLS(Multi-Protocol Label Switching) are linked. CONSTITUTION: In an MPOA network of the starting point, a packet is transmitted from an original point of MPC(MPOA Client)(401) to an entering point of LER(Label Edge Router)(403) through a data direct virtual channel connection. In an MPLS network as a backbone, the packet is transmitted through a path of LSP(Label Switch Path). Also, in an MPOA network of the destination point, a packet is transmitted from an outgoing point of LER(Label Edge Router) to a destination point of MPC through a data direct virtual channel connection. Thereafter, the MPOA network detects the flow of packet and sets up a shorter way virtual connection from the original point of MPC(401) to the entering point of LER(403).

Abstract: PURPOSE: A metric information collecting method of hierarchical network is provided to provide a high quality path according to a service type in case of a path request between nodes by selecting a metric of priority according to a service type or a service type combination, selecting an uplink with the best metric value selected for the service type or a service type combination, setting the metric information of the selected uplink as metric information for an upper level link. CONSTITUTION: An upper level node determines whether metric information of an internal link is to be expressed independently by service types or to be expressed in a combination form of the service types(S401). If the metric information is to be expressed independently by each service type, the upper level node selects a representative uplink according to the service type from an uplink list managed by the internal link(S402) and sets metric information of the selected uplink as metric information collected according to each service type of the internal link(S403). If the metric information is to be expressed in the combination form of the service types, the upper level node selects a representative uplink according to the service type combination from the uplink list managed by the internal link(S404), and sets the metric information of the selected uplink as metric information collected according to the service type combination of the internal link(S405).
