摘要： An optical transmission apparatus includes redundant line cards each installed with hardware and a CPU. The hardware obtains failure information on redundant lines including a working line and a protection line, and the CPU determines switching control of the redundant lines based on the obtained failure information. Further, the hardware switches the redundant lines based on switching control determined by the CPU, so as to transmit an SDH/SONET optical signal. In the apparatus, from or to hardware installed in each of the redundant line cards, the failure information obtained by the hardware is communicated to hardware installed in a neighboring line card.

摘要： An optical transmission apparatus includes redundant line cards each having a plurality of ports, a hardware unit and a CPU. The hardware unit obtains failure information on redundant lines for each port. The CPU determines switching control of the redundant lines based on the failure information. Then, the hardware unit switches the redundant lines based on the switching control determined by the CPU, so as to transmit an SDH/SONET optical signal in a ring network. The CPU of one of the line cards is set as a master CPU on the corresponding line card to control switching of the redundant lines. Further, the CPU of the other line card is set as a slave CPU.

摘要： A communication processing apparatus appends group information representing a group to received communication frames. Group information to be appended to the communication frames is changed on a predetermined cycle. The communication frames processed in each processing unit are counted separately for each of the group information appended, and the count value is collected in each processing unit. With a communication processing apparatus, such as a switch and a router, which has a plurality of processing units (device), performs processing by each of the processing units on the communication frames received from a receiving unit, and transmits the processed communication frames from a transmitting unit, it is possible to realize a communication processing apparatus and a totalizing system capable of accurately counting and collecting the communication frames while performing an operation when totalizing the number of communication frames processed in each of the processing units.

摘要： A path protection method is disclosed that is capable of path protection without extra cost and able to improve path switching efficiency. The method includes the steps of associating a virtual network identifier assigned to one or more users with a virtual network identifier for management, the virtual network identifier assigned to one or more users being regarded as one path to set a path for current use and a spare path; and when switching the currently-used path and the spare path, according to service class information included in the virtual network identifier for management, a path corresponding to a virtual network identifier for management having a higher service class than other paths is preferentially switched to.

摘要： A high-speed sprchronous multiplexing apparatus has a low-speed device and a high-speed device and employs electrical signals to interface the devices with each other. The low-speed device is connected to a low-speed digital circuit. The high-speed device is connected to a high-speed synchronous multiplexing circuit. The apparatus also has a clock supplier for supplying a reference clock signal that defines a communication rate, to each of the low- and high-speed devices. The apparatus further has an alarm processor for separating faults in the low- and high-speed devices. The low- and high-speed devices are interfaced with each other with the use of the reference clock signal and electrical STM-0/STS-1 signals that employ a frame signal synchronized with the reference clock signal.
