摘要： Network repeaters which each implement a redundant switching function previously grasp connection states of ports of a network system by using an inquiry frame and an exchange frame. At the time when a line is broken, when actively confirming a state of a port connected to a port in which a line is broken via a downstream device, the network repeaters each grasp that which portion of the line is broken and determine whether a switchover is required. Through the process, the network repeaters each prevent a useless switchover such as switching-back immediately after the switchover, and at the same time since a mechanism of waiting for a given length of times is not required, they each perform a fast switchover.

摘要： A method for detecting unavailable network connections comprises, at a first data processing node that is hosting a transport protocol connection that uses a plurality of sequence values to identify messages sent to a peer node, wherein the first node is communicatively coupled to a second data processing node serving as a redundant backup, periodically sending a checkpoint sequence value to the second node; detecting that either the transport protocol connection or a process using the transport protocol connection is unavailable, without use of a timeout; and in response thereto, sending a notification to the peer node, wherein the notification includes the checkpoint sequence value. One embodiment provides for rapidly detecting and responding to failure of a TCP process without using long timeouts as conventionally provided in long-lived applications that run on top of TCP.

摘要： A redundant control system for controlling an electromechanical system is provided. The control system includes a first processor, a second processor, an input-output node, a first communication channel, a second communication channel, and a signal selector. The first and second processors have a control algorithm and state variables resident thereon. The first and second processors each generate an output signal based on the control algorithm, the state variables, and an input signal from the electromechanical system. The first communication channel communicates the input signal and the output signal between the first processor and the input-output node, while the second communication channel communicates the input signal and the output signal between the second processor and the input-output node. The signal selector communicates either the output signal from the first processor or the output signal from the second processor to the electromechanical system.

摘要： According to the present invention, an information network wherein, packets can be forwarded between entities on a network along a plurality of lines, each line carrying separate copies of information. If a portion of one copy of the information is lost due to line failure, for example, other copies flowing along different lines can be used to reconstruct the lost information. In a representative embodiment, a plurality of LAN lines respectively connect between terminals and LAN-to-LAN forwarding devices or between two LAN-to-LAN forwarding devices. The terminals or the LAN-to-LAN forwarding devices are respectively provided with multiple line transmitting units for respectively transmitting the same packets to the plurality of LAN lines substantially contemporaneously. There are also provided multiple line receiving units for respectively selecting any of the same packets sent from the plurality of LAN lines and receiving it.

摘要： An optical one-to-one protection switching apparatus exchanges signals between a transmit node and a receive node. If a fault is detected in the first transmission line (down-stream), a controller in the node controls a drive circuit so as to shut off a gate. Then, the controller in the transmit node upon receiving a switching request from the receive node, controls the drive circuit so as to shut off the gate. Thereby, the optical switch is switched. The transmitter of the client terminal is thus connected to the second transmission line (down-stream). Upon receiving the switching request from the transmit node, the optical switch in the receive node is switched. Thereby the receiver in the client terminal is connected to the second transmission line (down-stream).

摘要： An alternate server system for continued network operation in the event of a network server failure. The alternate server system integrates a number of main servers with a backup server and a number of workstations. The backup server periodically takes snapshots of selected application data sets on the main server. In the event of a main server failure, the backup server gives users of the workstations the option to continue running applications on the backup server using the selected backup data. When the main server is returned to operation, the alternate server system discontinues execution of applications on the backup server, updates modified data, and restarts the applications on the main server.
