摘要： A packet switch identifies a communication flow carried across an IP network, observes the communication flow, and acquires statistics data thereof, such as the number of packets that passed through the switch, the number of discarded packets, time at which the packets arrived at the switch, and time at which the packets were sent out from the switch. The packet switch continues to acquire the statistics data on the communication flow while the communication flow continues. If the packet switch performs a relay function, it sends the locally obtained statistics data to the adjoining packet switch placed downstream. If the packet switch is a node placed on either end edge of the network, it gathers the statistics data obtained by and delivered from other switches in the network and sends the gathered statistics data to the network management system.

摘要： A packet forwarding device changes packet transfer performance according to a packet load, and ensures communication quality of an important packet while transfer performance is made minimum to suppress power consumption. The packet forwarding device includes a measuring section to measure the packet load for each packet importance degree, an estimation section to estimate a future packet load for each importance degree based on the measurement result, a performance determination section to determine performance for an operation based on the estimated load, which are provided in, for example, a traffic estimation/performance determination section. Reduction in the power consumption and assurance of the communication quality of the important packet are realized by a minimum performance determination based on an important packet estimation load in the performance determination section and a preferential process of the important packet in the packet forwarding device.

摘要： A data processor for latching in a floating point register floating point data having exponent parts of fixed and variable lengths, which are transferred from a main storage or an arithmetic unit as they are, but are not converted to another data expression type. When the data of the two representation types are to be input for computations from the floating point register or storage to the arithmetic unit, there is provided circuitry for controlling the data to be computed after that data has been converted into data having an exponent part of fixed length representation, in the arithmetic case of data having an exponent part of the variable length representation, and data to be computed without any data conversion in the arithmetic case of data having an exponent part of the fixed length representation. By thus controlling the two computations discriminatively, it is possible to realize the processing time periods matching the respective data widths.

摘要： In a conventional “distributed” integrated network node architecture, specific judgment processes cannot be executed in any routing and transferring unit. The routing and transferring unit is required to share judgment process related information with an enhanced processing unit or other routing and transferring units. Thus, when using enhanced processing units, manufacturing costs increase, while processing speed decreases when routing and transferring units cooperate. If any flow is disposed during a transfer from a packet transferring unit in a routing and transferring unit to a processing unit, the packet is disposed regardless of packet priority. In the present invention, a packet related to a specific judgment process is always transmitted to a specific routing and transferring unit from a line interface unit. If an inputted flow is over the transferring capacity, the line interface unit analyzes the packet header and determines the type, transport priority, and disposal priority of the packet.
摘要翻译：在传统的分布式集成网络节点架构中，不能在任何路由和传送单元中执行特定的判断过程。路由和传送单元需要与增强处理单元或其他路由和传送单元共享判断过程相关信息。因此，当使用增强的处理单元时，制造成本增加，而路由和传送单元协作时处理速度降低。如果在从路由和传送单元中的分组传送单元传送到处理单元的过程中布置任何流程，则不管分组优先级如何，分组被布置。在本发明中，与特定判断处理相关的分组总是从线路接口单元发送到特定的路由和传送单元。如果输入的流量超过传输容量，则线路接口单元分析分组报头并确定分组的类型，传输优先级和处置优先级。

摘要： A network switching device includes multiple ports, multiple switching processors, and a table manager. The switching processors respectively have an address table, a output port specification module, an update requirement determination module, and a table update module. The output port specification module refers to a destination address in received data and the address table and specifies a output port for sending the data among the multiple ports. The update requirement determination module determines requirement for update of the address table with regard to a source address in the data. The table manager has an update detail acquisition module and an update request module. Upon determination of the requirement for update of the address table, the update detail acquisition module obtains an update detail of the address table from one of the switching processors. The update request module sends an update request to the switching processors, based on the update detail.
