摘要： A method of controlling a network switching device is provided. Perform a mode-process including setting the determination-operation mode of a target switching block to a determination-operation mode that is different from the determination-operation mode of the first switching block while the first switching block is handling the switching-determination process. The target switching block is one switching block selected from the second switching blocks. Then, perform a switchover process including starting the switching-determination process using the target switching block instead of the first switching block, after completion of the process of setting the determination-operation mode of the target switching block.

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： In the case of a “distributed” integrated network node (architecture), a specific judgment process cannot be executed in any routing and transferring unit. The routing and transferring unit has been required to share such judgment process related information with an enhanced processing unit or with other routing and transferring units. Thus the manufacturing cost has increased when using an enhanced processing unit and the processing speed has been lowered unavoidably when cooperation is required among routing and transferring units. Those have been conventional problems. Furthermore, if any flow is disposed during a transfer from a packet transferring unit provided in a routing and transferring unit to a processing unit, the packet is disposed regardless of the packet priority. This has also been another conventional problem. According to the present invention, however, it is ruled that a packet related to a specific judgment process is always transmitted to a specific routing and transferring unit from a line interface unit. And if a flow is inputted and it is over the transferring capacity between a line interface unit and a routing and transferring unit, the line interface unit analyzes the packet header and determines the type, transport priority, and disposal priority of the packet.

摘要： A transmitter communicates with a receiver and an error corrector corrects bit errors generated during data transmission. The transmitter has a scrambler unit that scrambles data so that a running disparity of 0 and 1 in the input data is substantially zero. A bit-string converting unit 15 that adds bit data for ensuring a maximum run length of a serial bit string of the scrambled data and converts control information to bit data of a fixed value. A synchronization timing generating unit 16 divides the transmitted data by a constant interval and converts the transmission data to a data block. A bit-string converting unit extracts a fixed-value bit pattern of the control data from the bit string of the data block, converts the bit pattern to the control information, and discriminates the data and the control information. A descrambler unit reconverts the data-scrambled data to the data before scrambling.

摘要： This invention provides a data transfer control device for carrying out data transfer using a plurality of transfer resources. The data transfer control device comprises a transfer resource management portion that set the plurality of transfer resources to either one of a transfer-enabled state whereby data transfer is enabled and a plurality of standby states on the basis of a load on the data transfer control device and that manages the plurality of transfer resources so as to assume the set operating status; and a load distribution portion that distributes the data to transfer resources that have been set to the transfer-enabled state. The plurality of standby states are states which data transfer is disabled and which mutually differ at a minimum in terms of at least one of power consumption level and transition time to the transfer-enabled state.
