摘要: An optical packet switching device causes branching of an optical packet that is input to an optical switch and detects a synchronization pattern having a predetermined number of bits from the branched optical packet. Then, the optical packet switching device calculates a synchronization point indicating a location of the synchronization pattern with respect to a detection timing and controls, in accordance with the calculated synchronization point, a delay amount of a delay element that delays an optical packet ON signal that is output to the optical switch.

摘要: A transmission device capable of configuring a communication network over which MC packets are forwarded in a way that does not use bands with futility is disclosed. The transmission device is so configured to transmit, when receiving a multicast packet from a host, to the other transmission device the multicast packet that is to be discarded by the transmission device having no necessity of forwarding the received multicast packet to the next transmission device.

摘要: A first node apparatus includes: ports; a storage device; and receiving, updating, and transmitting circuits. The storage device stores: information associating, with first identification information identifying a first frame, information distinguishing a first port having been used as a destination port when the first node apparatus has transmitted the first frame; and information associating, with each node apparatus, state information indicating whether frame transmission from each port is feasible. The receiving circuit receives, from a second node apparatus, a second frame including second identification information. When the second identification information is identical with the first, the updating circuit updates the state information associated with a node apparatus being a destination of the second frame to make the state information indicate frame transmission from the first port is not feasible. The transmitting circuit selects a second port from which transmission of the second frame is feasible, and transmits the second frame.
