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.
摘要翻译：在“分布式”集成网络节点（架构）的情况下，不能在任何路由和传送单元中执行特定的判断过程。路由和传送单元已经被要求与增强处理单元或其他路由和传送单元共享这样的判断过程相关信息。因此，当使用增强处理单元时，制造成本增加，并且在路由和传送单元之间需要协作时，不可避免地降低了处理速度。那些是常规问题。此外，如果在从设置在路由和传送单元中的分组传送单元传送到处理单元的传送期间设置任何流程，则分组被布置，而不管分组优先级如何。这也是另一个常规问题。然而，根据本发明，规定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。并且如果输入流，并且在线路接口单元和路由和传送单元之间的传输容量之上，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。
