    摘要： Provided is a network management system for managing a plurality of packet relay devices, the network management system comprising: the plurality of packet relay devices constituting networks; and a display device for displaying configurations of the networks, in a case where it is determined that a virtual packet relay device identifier of the virtual packet relay device that is assigned a second-network identifier associated with the extracted second-network identifier is registered in a first-network configuration table, a first-work identifying module is configured to associate a first-network identifier that is associated with the virtual packet relay device identifier with the obtained configuration information, and register the association between the first-network identifier and the obtained configuration information in the first-network configuration table.

    摘要： There are provided a virtual network management system and a network device that can identify the topology of a virtual network, estimate a virtual network to which various computing devices belong and the locations of the computing devices, and present the virtual network and the locations to a network administrator. In a network management device, the configurations of packet transmission devices and a MAC learning table are managed. A virtual network to which given virtual computing units are connected is identified from information about a virtual packet transmission device identifier, a VLAN identifier, a MAC address, and a packet transmission port number acquired from the MAC learning table. The locations of the virtual computing units in the virtual network are estimated, and the topology is drawn on the screen of a display.

    摘要： A network controller, capable of high-speed extraction of malicious traffic from networks and determining characteristics of such traffic, includes a unit for accumulating a number of packets for each arbitrary itemset included in the header portions of packets to be transferred, and a unit for determining whether the accumulated value obtained by the accumulating unit exceeds a predetermined threshold, and determines the types of packets to be transferred from accumulated values of the itemset and an itemset different from the itemset when the number of packets exceed a threshold.

    摘要： A routing apparatus includes a plurality of routing units and function units. The routing unit receives a packet from each port, and uses header information contained in the packet to judge whether the packet should be transmitted to the function unit. In the case where the packet should be transmitted to the function unit, the routing unit adds a first identifier to the packet and transmits it to a transmission unit. The function unit receives the packet containing the first identifier from the transmission unit, and executes a predetermined processing for the packet. The function unit adds a second identifier to the packet and transmits it to the transmission unit.
