  • Network management apparatus and network management method
    Patent number: 9590864
    Abstract: A network management apparatus includes a first storage unit, a second storage unit, and a controller. The first storage unit stores therein communication groups included in the same subnet and information about communication devices belonging to the respective communication groups in association with each other. The second storage unit stores therein for each of the communication devices a port of a relaying device connected to the communication device as a connection destination port. The controller allows the relaying devices to perform communication between the connection destination ports on the basis of the first storage unit and the second storage unit to allow communication only between the communication devices belonging to the same communication group.

  • Communication device
    Patent number: 6882648
    Abstract: A communication device wherein path selection is performed taking account of the conditions of individual paths on a network. Storing means stores information relating to a plurality of paths, and selecting means selects the information relating to one of the paths stored in the storing means. Packet generating means generates a packet with a header matching the information relating to the path selected by the selecting means, and transmitting means transmits the packet generated by the packet generating means.
