  • Publication number: 20100232291
    Abstract: In a data transmission device and method provided with e.g. duplexed switches outputting frames in the order of input for continuing the communication without instantaneous interruptions even though one of the switches are faulted, input interfaces generate frames in which every time data is inputted, input order information indicating the input order is added to the data together with unique information of each input interface and providing the frame generated to the switches in parallel. At least one output interface sequentially stores the frames outputted from the switches for every unique information and selects a first arrived frame among the frames stored with same input order information.

  • Publication number: 20100098088
    Abstract: For precluding useless resources of a pseudo wire in a device distributing pseudo wires to lighten the receiving capacity, MPLS (Multi Protocol Label Switching) tunnels are established with an opposing device. From among the established MPLS tunnels, an MPLS tunnel having a remaining resource for a pseudo wire at interfaces having the MPLS tunnels in response to a pseudo wire establishment request is selected and the information of the selected MPLS tunnel associated with a label of the pseudo wire having the remaining resource is distributed to the opposing device. Alternatively after having established the MPLS tunnels with the opposing device, when a distribution request of the pseudo wire information associated with desired MPLS tunnels is received from the opposing device having received the pseudo sire establishment request, a label of the pseudo wire is similarly determined and distributed to the opposing device together with the information of the MPLS tunnel passing the pseudo wire.

  • Publication number: 20080186951
    Abstract: Disclosed is a method of setting a bidirectional path between a first node and a second node in a network. A first path from the first node to the second node is established by a first path establishing procedure in which a first path message including a record of a route through which the first path message is forwarded from the first node to the second node. A second path from the second node to the first node along the route of the first path in the backward direction is established by a second path establishing procedure in which a second path message including a route specification determined based on the record of the route included in the first path message is transferred from the second node to the first node.

  • Patent number: 7394831
    Abstract: A method for time-division multiplexing including steps of generating a plurality of first signals and a plurality of second signals to which specific pulse trains for frame synchronization are allocated respectively; generating low speed signals of plural channels including the first and second signals and transmission signals; a conversion step; and time-division multiplexing the low speed signals after the conversion step, thereby obtaining high speed signals. When applied to SDH, for example, the first and second signals may be A1 bytes and A2 bytes respectively, and the transmission signals may ho payload signals. According to one aspect of the invention, at the conversion step, the first and second signals in each channel are panty convened into either of “1/0” alternating signals and “0/1” alternating signals. Consequently, it becomes possible to reduce the number of successive same code and to diminish the deviation of the mark rate.
