Abstract: A link configuration and state management method using a shared memory is provided to improve performance of an overall system by generating a shared memory and a link information table, adding and deleting a link, and recovering a generated failure. When a system starts, a link information table and a shared memory are generated and initialized(S01). A file regarding link configuration information of the system is read(S02) and sets link configuration and state information is set in the link information table(S03). A configuration state control process enters a standby state(S04). When a link configuration addition/deletion request command is received from the system or an operator(S05), it is checked whether the command link configuration addition request command(S06). In case of the link configuration addition request command, a process for adding link configuration is performed(S07) and sets the added link configuration information in the link information table(S08). In case of the link configuration deletion request command, a process for deleting a link configuration is performed(S10). A processing result is reported to a management system or the operator(S09). When failure generation or recovery information with respect to a link is received from a management system(S11), it is checked whether the information is the failure generation information(S12). In case of the failure generation information, a failure processing is executed(S13) and failure generation information is set in the link information table(S14). The failure generation information and the processing result are reported to the management system(S15).

Abstract: PURPOSE: A defect management method of a network management system is provided to enable a network management agent to transmit a defect-related message to a network management manager by using a trap stipulated in an SNMP, thereby enabling a real-time defect management function. CONSTITUTION: Trap define information and a defect management table are initialized(S101). A network management manager is in standby state(S102). If a trap message is received(S106), the manager checks whether the trap is defined at the defect management table(S107). If so, the manager extracts device information from the content of related object information of the trap message(S108). The manager retrieves a trap defect code number, information showing whether trap information is related to defect generation, and information on a trap level defect(S109-S112). The manager combines recovery information, the defect code number, defect contents, and the device information together, and configures a defect message(S113). The manager outputs the defect message to an operator(S114).

Abstract: PURPOSE: A line interface statistics collecting method in a distributed processing high speed router is provided to quickly and effectively perform a line interface statistics collection request received from an operator terminal and a network management system by using a high speed router including line cards with a control processor, and stably operate the high speed router. CONSTITUTION: A data is initialized to collect a line interface statistics(S301) and comes in a standby state to wait for a statistics collection request from an operator terminal or a network management system(S302). When the line interface statistics collection request is received from the operator terminal(S303), a line card and a port number requested by the operator terminal are analyzed(S304), and a related transmission and reception counter information desired to be collected by the operator terminal is collected from control processors of the obtained line card(S305). The collected counter information is formatted to a form to be outputted to the operator terminal(S306), and the line interface statistics collection result is provided to the operator terminal(S307). When a line interface statistics collection request is received from the network management system, that is, when a message for an MIB(management information base) object data searching request is received(S308), the received message is analyzed and a PDU(Protocol Data Unit) is extracted(S309), and the requested statistics MIB is searched(S310). A related transmission and reception counter information is collected by using the searched information(S311), and the collected related transmission and reception counter information is combined(S312). The combined related transmission and reception counter information is converted into an MIB object information requested by the network management system and a PDU to be used when responding to the network management system is generated(S313). The MIB object data searching result using the generated PDU is provided to the network management system(S314).

Abstract: PURPOSE: A method for notifying excessive use of time limit in an always on/dynamic ISDN service is provided to provide time limit excess information to a user, thereby enabling the user to decide whether to use a B channel. CONSTITUTION: If a subscriber requests AO/DI(Always On/Dynamic ISDN) data call connection, it is examined whether accumulated use time exceeds time limit. If accumulated use time exceeds time limit, time excess information is generated in a connection message and transmitted to the subscriber. If accumulated use time does not exceed time limit, the normal connection message is transmitted to the subscriber for proceeding a call and a monitor timer is set up. If use time exceeds time limit in state of proceeding call, time excess information is generated in a notify message and transmitted to the subscriber.
