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： A packet communication system of the present invention has first mode, second mode and third mode to apply to input packets. The first mode is a mode that decides priority of the packet by at least one of the address information and the application information, the second mode is a mode that decides priority of the packet by the DS value, the third mode is a mode that decides rewrite the DS value by at least one of the address information and the application information. A control unit of the packet communication system switches a mode to apply an input packet of the first mode, the second mode and the third mode based on the packet header information of the input packet.

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 shaping unit includes FIFOS for accumulating a packet which is so designed as to arrive at a destination address. A packet (ordinary packet), which has one destination address, is accumulated into the FIFO corresponding to the one destination address. A packet (virtual multicast packet), which will be copied in the downstream of the shaping unit then to arrive at two destination addresses, is accumulated into either of the FIFOS. A packet read unit transmits the virtual multicast packet, which is read from either of the FIFOs, and the ordinary packet, which is read from the one of the FIFOS, to a multiplexing circuit in such a manner that total bandwidth of both packets is controlled.

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。

摘要： To provide a packet forwarding device which minimizes degradation in packet forwarding performance at the time of execution of filtering there is provided a technique in which a destination decision processing unit of a destination decision and filtering unit decides whether to execute filtering on the basis of at least one of an input interface, an input port number, an output interface, and an output port number of an input packet and a plurality of pieces of information constituting the header of the packet. A filtering unit executes filtering only for a packet for which execution of filtering is decided. The packet forwarding device with the destination decision and filtering unit need not execute filtering for all packets and can minimize degradation in packet forwarding performance caused by filtering.
