摘要： An edge router measures a traffic volume inputted into a network, and the measurement result is notified to a network management server. If the network management server judges that the notified traffic volume is “smaller” than a capacity of a second core router, it will direct a first core router to shift to a power saving mode. The first core router notifies the edge router of the shift to the power saving mode, and the edge router updates a routing table so that the packet to the first core router may be bypassed to the second core router. The first core router shifts to the power saving mode that does not perform packet transfer, and reduction in electric power is realized.
摘要翻译：边缘路由器测量输入到网络的流量，并将测量结果通知给网络管理服务器。如果网络管理服务器判断所通知的业务量比第二核心路由器的容量“小”，则它将引导第一核心路由器转移到省电模式。第一个核心路由器通知边缘路由器转移到省电模式，边缘路由器更新一个路由表，使得到第一个核心路由器的数据包可能被旁路到第二个核心路由器。第一核心路由器转移到不执行分组传输的省电模式，并实现电力的降低。

摘要： A system permitting alteration of the information processing position, where an existing information system is used, while minimizing alterations in configuration or the like, is to be provided. Intelligent nodes each having an information processing section and any desired address altering section are arranged on boundaries of a network where packets are likely to pass. This node has a flow table for recognizing as a flow a group of packets transmitted from each user's terminal, a flow status table for determining the connection state and the next destination address or the final destination address of each flow, and a module to observe the loaded state of its own information processing function. It rewrites the destination address of any flow not in a connection-established state in the flow status table to a less loaded one out of its own information processing function section or external information processing apparatus.

摘要： Disclosed herewith is a network that can connect as many VPNs as possible to itself. In order to realize such a network, in the frame transfer method of the present invention, which enables a transfer path to be formed between nodes in the network so as to transfer frames, a terminal for transmitting frames or node located outside the transfer path, upon transmitting a frame through the transfer path, writes the transfer path selection information related to the transfer path and the output line information related to the output line from the terminating node of the transfer path in the frame according to the destination information set in the frame and transmits the frame to the destination. The starting node of the transfer path decides the transfer path used for transferring the frame according to the transfer path selection information set in the frame to transmit the frame while the terminating node of the transfer path decides the output line used to output the frame therefrom according to the output line set in the frame, thereby transmitting the frame to the output line.
摘要翻译：这里公开的是可以将尽可能多的VPN连接到其自身的网络。为了实现这样的网络，在本发明的帧传送方法中，能够在网络中的节点之间形成传送路径以便传送帧，用于发送帧或位于传送路径外部的节点的终端，在通过传送路径发送帧时，根据在帧中设置的目的地信息将与传输路径有关的传输路径选择信息和与传输路径的终止节点相关的输出线信息写入帧中并将帧发送到目的地。传输路径的起始节点根据在帧中设置的传输路径选择信息来确定用于传送帧的传输路径以发送帧，而传输路径的终止节点根据传输路径的终止节点决定用于输出帧的输出线到帧中设置的输出线，从而将帧发送到输出线。
