  • Packet communication method with increased traffic engineering efficiency
    Patent number: 7525919
    Abstract: When a lower layer address pair of a transferred lower layer frame is counted a predetermined number of times or more, a packet transfer apparatus (2) sends the lower layer address pair to a frame transfer apparatus (3). The frame transfer apparatus (3) counts the transfer frequency of the lower layer frame having the lower layer address pair.
    Type: Grant

    Date of Patent: April 28, 2009
    Assignee: Nippon Telegraph and Telephone Corporation
    Inventors: Kenichi Matsui, Takeshi Yagi, Yuuichi Naruse, Junichi Murayama, Masaki Kaneda
  • Packet communication network, route control server, route control method, packet transmission device, admission control server, light wavelength path setting method, program, and recording medium
    Publication number: 20060053221
    Abstract: A route control server (1) sends destination information acquired by a router (2) in a managed area and transfer management information corresponding to the destination information to another route control server and determines the output interface of a packet on the basis of the destination information and transfer management information. A packet transfer apparatus (3) executes mutual conversion and transfer of an upper layer packet on a user terminal side and a lower layer frame on an optical wavelength path side. An admission control server (4) sets, of the optical wavelength paths of the photonic network, an optical wavelength path formed from a cut-through optical wavelength path which has a guaranteed band and directly connects packet transfer apparatuses of transmission source and destination in accordance with an optical wavelength path connection request from a transmission source user terminal.
