    摘要: In a network including: a first node(s) controlled by a control apparatus in a centralized manner; a second node(s) storing, for a predetermined period, entries in each of which, based on a source address of a received packet, its own port and information about a node address(es) to which packets can be forwarded from the port are associated with each other and performing packet forwarding by referring to a group of entries and determining a port corresponding to a packet destination; and the control apparatus, the control apparatus causes the first node(s) connected to the second node(s) to transmit a destination learning packet to the second node(s) to cause the second node(s) to learn information about an address(es) to which packets can be forwarded from a port(s) of the second node(s) at predetermined time intervals.

    摘要: In an OpenFlow network, it is determined which port of which node device a terminal connected to a group of node devices is connected to, by only using the source MAC address and port number of a packet transmitted from the terminal. Specifically, the node device compares a set of the port number and source MAC address information of a packet transmitted from the terminal to the node device with a set(s) of a port number and MAC address information held in a preliminary search table to check whether they match each other. When the comparison does not result in a match, the node device notifies the controller by using the inquiry information (packet-in) function of OpenFlow. Furthermore, the node device compares the destination MAC address information of the packet with a set(s) of MAC address information held in a final search table to check whether they match each other.

    摘要: This invention is directed to a polyimide film useful as use applications for electronic materials; a liquid crystal aligning film using the same; a liquid crystal display element provided with the liquid crystal aligning film; and a polyamic acid used as a raw material of the polyimide constituting the polyimide film. The polyimide used for preparing the above polyimide films, consists of a diamine component, the 50% by mol or more based upon the total diamine, of which is a diamine having a core structure having no polar group such as 1,2-bis(4-(4-aminobenzyl)phenyl)ethane, 1,6-bis(4-(4-aminobenzyl)phenyl)hexane, 1,1-bis(4-(4-aminobenzyl)phenyl)heptane, etc., and a tetracarboxylic acid dianhydride, and if necessary, an aminosilicon compound, is used as a liquid crystal aligning film.
