摘要： PROBLEM TO BE SOLVED: To retrieve and display an accumulated database when a computer system breaks down and to prevent the system from breaking down owing to the fault of a pattern similar to a former fault. SOLUTION: The backup method in the computer system 1 having a storage device 4 storing the database 41 and a processor 6 accessing to the database by an application program PR1 and executing a processing is provided. In such a case, the database 41 is stored by a data system fitted for data work by the application program PR1, data of the database 41 is converted into data of a hyper text system and hyper text data 51 for backup is generated. When the access of the database 41 by the application program PR1 becomes impossible in the processor 6, a browser PR2 accesses to hyper text data 51 and executes the processing.

摘要： PROBLEM TO BE SOLVED: To provide a traffic control method, which can prevent the number of cells transmitted to an asynchronous transfer mode(ATM) from exceeding a maximum transmission rate. SOLUTION: At the time of transmitting a frame F from a frame relay network FR1 to inter-work function(IWF) 21a, a traffic control part 56, which the frame relay network FR1 possesses, measure transmission data quantity per measurement time in a data link connection identifier(DLCI) connecting the frame relay network FR1 and IWF21a. Then, the traffic control part 56 detects a traffic restriction level, corresponding to the measured transmission data quantity. A traffic restriction processing corresponding to the restriction level is executed, and frame transmission by the transmission destination terminal of the frame F is suppressed. Thus, the number of cells S transmitted to the ATM network 20 is prevented from exceeding the maximum transmission rate which has been contracted.

摘要： PURPOSE:To enable packet passing control to be comducted to be conducted without increasing the load of a system. CONSTITUTION:This system is provided with chase number storage part 11e for storing the chase number of a finally transmitted packet for each pair of addresses in which either a transmission source address or a destination address is made different at least, and a chase number addition part 11b adds the chase number to the packet at the time of packet reception and continues the packet to a queue corresponding to a transmission priority level. At the time of packet transmission, a queue managing part 11f decides packets to be transmitted in the order of priority levels and reception, a chase number processing part 11g calculates a chase number Ni of the finally transmitted packet among the packets provided with the same transmission source address and the same destination address as that packet from the chase number storage part 11e, when a chase number N of a packet to be transmitted is larger than the chase number Ni of the finally transmitted packet, that packet is transmitted, the contents of the chase number storage part 11e are updated with the chase number N of the packet and when the chase number is smaller, that packet is not transmitted but abandoned.

摘要： PURPOSE:To facilitate link establishment at a layer-2 level even in the case of taking any route concerning the system for establishing a link at the layer-2 level, at the network equipped with a normal route via a packet exchange and a backup route via a non-packet network as the communication routes between packet terminals. CONSTITUTION:In the case of executing communication between packet terminals, when a received frame address is same as the own address, a received frame is judged as a command frame and when the received frame address is different from the own address, the received frame is judged as a response frame. Afterwards, the state of the like at a layer 2 is judged and when the link is not established, the response frame is transmitted by changing the own address so as to establish the link.

摘要： PURPOSE:To obtain the significant error log information and to curtail the number of times of write of a nonvolatile memory by collecting only error log information by a first machine check after turning on a power source of a device. CONSTITUTION:When a control means (flip-flop) 6 is turned off by turning on a power source of a device, and a first machine check is detected after turning on the power source of the device, error log information is collected and stored in a nonvolatile memory 3. Also, when the control means 6 is turned on, thereafter, even if the machine check is detected, the error log information is not collected, and the error log information is not stored in the nonvolatile memory 3. Accordingly, only the error log information by a first machine check after turning on the power source can be collected and stored. In such a way, significant error log information is obtained, and the number of times of write to the nonvolatile memory 3 to which the number of times of write is limited is curtailed.

摘要： PURPOSE:To start the operation of each slave exchange in the order suitable for the operation of an exchange system by designating the transfer sequence optionally when a slave exchange data is transferred simultaneously to plural slave exchanges. CONSTITUTION:A priority registration means 100 registers sets of priority p-pm corresponding to slave exchanges 21-2n. When the necessity of transferring a slave exchange data (d) respectively to the plural slave exchanges 2 takes place, a transfer destination selecting means 200 references the priority (p) registered already by the priority registration means 100 and selects a slave exchange 2 with higher priority (p) with priority as a transfer destination slave exchange of the slave exchange data (d). Thus, when the slave exchange data is transferred simultaneously to the plural slave exchanges, it is possible to designate optionally the order of transfer and the start of the operation of each slave exchange is attained in the order suitable for the operation of the exchange system and the service performance of the relevant exchange system is improved.

摘要： PURPOSE:To initialize a memory and a memory circuit without using any exclusive hardware by supplying the output received from an address register storing the address of the memory to the memory circuit at initialization. CONSTITUTION:The specific data is set at a memory data register 4 and a 1st address register 2 storing the address of a memory 1 is added via an adder 3. At the same time, the entire area of the memory 1 is initialized. In such a case, the optional several bits of the register 2 are taken out and supplied to a memory circuit (internal register) 6 via a multiplexer 9. Thus the optional data supplied from an arithmetic circuit 5 is also set at the register 6. Then the register 6 is also initialized and no addition circuit is required for initialization of a 2nd address register 7 which stores the address of the register 6. Thus the hardware quantity is reduced.

摘要： PURPOSE:To improve the reliability of reloading information by updating the data reloading information simultaneously with the storage of error information to an EEPROM. CONSTITUTION:When an error is generated in a diagnosed circuit 111, a storage control means 131 executes the scan-out of the error information, which are stored in the flip-flop in the circuit 111 and the information are collected and supplied to an EEPROM 121. The EEPROM 121 holds the supplied error information. An updating means 141 updates the reloading information, which are held by the EEPROM 121, of the EEPROM itself. Thus, the reliability of the reloading information is improved.
