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： In an optical transmission device, firmware that operates within a CPU of a first LIU and firmware that operates within a CPU of a second LIU periodically measure a load status of a CPU via an OS, respectively. Switchover control of a master CPU is performed according to a load status of a CPU measured by the firmware of each LIU. For example, when a load status of the CPU of the second LIU is lower than that of the CPU of the first LIU, a master CPU that performs switchover control of a predetermined port is switched to a slave CPU in the first LIU, and a slave CPU related to the predetermined port is switched to a master CPU in the second LIU, thereby dynamically changing the setting.

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.
