    • PURPOSE: A method for managing a measuring threshold value of an optical transmission device is provided to set various measuring threshold values in an optical transmission device unit, and to inform a user that measuring performance values of each unit reach the threshold values, thereby exactly finding a position of a unit having an error and managing a failed threshold value. CONSTITUTION: A performance value collection module of a control unit(102) is periodically driven(211), and requests a current measuring performance value of a unit(101)(212). The unit(101) transmits the current measuring performance value to the control unit(102)(213). If an operator(108) transmits a threshold value setup request to the control unit(102)(214), a threshold value setup module of the control unit(102) sets a threshold value for a performance value of the unit(101)(215). The performance value collection module compares threshold values of the measuring performance value of the unit(101) and the set measuring performance value(216). If the collected measuring performance value exceeds the set threshold value, a threshold value exceeding alarm is generated for the operator(108)(217).
    • 目的:提供一种用于管理光传输设备的测量阈值的方法,以在光传输设备单元中设置各种测量阈值,并通知用户每个单元的测量性能值达到阈值,从而准确找到 具有错误并管理故障阈值的单元的位置。 构成:周期性地驱动控制单元(102)的性能值收集模块(211),并请求单元(101)的当前测量性能值(212)。 单元(101)将当前测量性能值发送到控制单元(102)(213)。 如果操作员(108)向控制单元(102)发送阈值设置请求(214),则控制单元(102)的阈值设置模块设置单元(101)的性能值的阈值( 215)。 性能值收集模块比较单元(101)的测量性能值和设定的测量性能值(216)的阈值。 如果收集的测量性能值超过设定的阈值,则对于操作者(108)(217)产生超过报警的阈值。

    • PURPOSE: A method for collecting performance value records in a polling method of an optical transmission device is provided to enable a central control unit to poll performance values of plural units to each control unit, and to collect performance value records, thereby distributing a communication load of the central control unit. CONSTITUTION: If a performance value collecting timer is operated(S311), a control unit(202) requests performance values of plural units(201) managed by the control unit(202)(S312). The corresponding units(201) transmit the corresponding performance values to the control unit(202) by responding to the request(S313). If a performance value record collecting timer is operated(S314), a central control unit(203) requests performance value records of the specific control units(202)(S315), and receives the performance value records from the specific control unit(202)(S316).

    • PURPOSE: A method for monitoring a state of a duplex processor to recover a temporary duplex channel communication fault of an ATM(Asynchronous Transfer Mode) exchange is provided to divide a case where a hardware fault is generated in a standby processor and a case whether a hardware fault is not generated, so as to effectively monitor an actual state of the standby processor. CONSTITUTION: A processor state monitor(31) delivers a state request to an active processor(32). The active processor(32) delivers the state request to a standby processor(33) to obtain a state of the standby processor(33). If a state response is not received from the standby processor(33) in a predetermined time, the active processor(32) sets up a state of the standby processor(33) as 'unknown' and transmits a state of the active processor(32) itself and the 'unknown' state of the standby processor(33) to the processor state monitor(31). If a frequency of 'unknown' states is over a predetermined frequency, or n, the processor state monitor(31) sets up a state as 'abnormal'. And if the frequency of 'unknown' states is not over the predetermined frequency, or n, the processor state monitor(31) maintains a prior state.
    • 目的:提供一种用于监视双工处理器的状态以恢复ATM(异步传输模式)交换的临时双工通信通信故障的方法,以分配在备用处理器中产生硬件故障的情况以及是否 不会产生硬件故障,从而有效监控待机处理器的实际状态。 构成:处理器状态监视器(31)向活动处理器(32)传送状态请求。 活动处理器(32)将状态请求传送到备用处理器(33)以获得待机处理器(33)的状态。 如果在预定时间内没有从备用处理器(33)接收到状态响应,则活动处理器(32)将备用处理器(33)的状态设置为“未知”,并且将活动处理器(32)的状态 )和待机处理器(33)的“未知”状态发送到处理器状态监视器(31)。 如果“未知”状态的频率超过预定频率或n,则处理器状态监视器(31)将状态设置为“异常”。 并且如果“未知”状态的频率不超过预定频率或n,则处理器状态监视器(31)保持先前状态。

    • PURPOSE: A priority buffer control algorithm in an ATM exchange system is provided to satisfy QoS for superior service by buffering cells of highest priority in the event of overload, and to improve satisfaction about overall service by providing equal service opportunity for lower cells in the event of normal traffic. CONSTITUTION: A priority buffer control algorithm in an ATM exchange system includes the following steps. When a cell of FULL_OVLD state and L2_OVLD state(S1) is entered through a cell entrance point(S2), it is decided whether the cell is L2_OVLD state(S3). If not, the cell is stored in a primary buffer counter(PBC), it is decided whether the counter exceeds threshold L2(S5). If PBC exceeds L2, the cell is changed into L2_OVLD state(S6), or if not, the next cell is waited(S7). If the cell is entered in L2_OVLD state, it is decided whether the cell is an upper cell or lower cell(S8). If the cell is a lower cell, it is decided whether the cell is in FULL_OVLD state(S9). If the cell is in FULL_OVLD state, the entered lower cell is removed(S10). If not, the lower cell is stored in a subsidiary buffer(S11).
    • 目的:提供ATM交换系统中的优先级缓冲区控制算法,通过在超载情况下缓存最高优先级的小区来满足优质服务的QoS,并通过为事件中的较低单元提供相等的服务机会来提高整体服务的满意度 的正常交通。 构成:ATM交换系统中的优先级缓冲器控制算法包括以下步骤。 当通过小区入口点(S2)输入FULL_OVLD状态和L2_OVLD状态(S1)的小区时,判定该小区是否为L2_OVLD状态(S3)。 如果不是,则将单元存储在主缓冲计数器(PBC)中,判定计数器是否超过阈值L2(S5)。 如果PBC超过L2,则将该单元变为L2_OVLD状态(S6),否则等待下一个单元(S7)。 如果在L2_OVLD状态下输入单元,则判定单元是单元还是下单元(S8)。 如果小区是较低小区,则确定小区是否处于FULL_OVLD状态(S9)。 如果单元格处于FULL_OVLD状态,则删除输入的下单元(S10)。 如果不是,则下部单元被存储在辅助缓冲器(S11)中。
