20110244813 | COMMUNICATION SYSTEM - This communication system is equipped with a plurality of transceiver devices each composed of a transmission device that transmits unit data and a reception device that receives unit data from the transmission device. The transmission devices are connected in series. Each of the transmission devices stores identification information for identifying the device itself. The transmission device accepts unit data from a front stage side. The transmission device generates identification information for identifying one of the transmission devices from information included in the accepted unit data, in accordance with a predetermined generation process. In a case that the generated identification information corresponds to the stored identification information, the transmission device transmits the accepted unit data to the reception device. In a case that the generated identification information does not correspond to the stored identification information, the transmission device sends the accepted unit data to a back stage side. | 10-06-2011 |

20120189011 | A COMMUNICATION APPARATUS, A COMMUNICATION SYSTEM AND A COMMUNICATION METHOD - A communication apparatus comprises: a memory unit which correlates a label assigned to a packet and an address of a source of the packet, and memorizes them as an entry; a receiving unit which receives a packet from a network; a learning unit which judges whether or not there exists an entry corresponding to the received packet in the memory unit, and in case there exists no entry corresponding to the received packet in the memory unit, stores a label assigned to the received packet and an address of a source of the received packet in the memory unit; and a processing unit which, in case there exists an entry corresponding to the received packet in the memory unit, assigns an address corresponding to the received packet to the received packet. | 07-26-2012 |
20120219003 | NODE, A MONITORING MANAGEMENT METHOD USED FOR IT, AND A TRANSFER SYSTEM, AN INPUT CIRCUIT AND AN OUTPUT CIRCUIT USING IT - [Issues] To provide a node (transfer device) which can process an OAM frame within an output line card. | 08-30-2012 |
20130121165 | COMMUNICATION DEVICE, AND SIGNAL DEGRADATION MONITORING SYSTEM AND METHOD - A communication device includes a receiving unit configured to receive a frame via a connected packet network, a transmitting unit configured to transmit the received frame and a self-originating frame to the packet network, a monitoring unit configured to monitor a flow rate of the transmitted frames, a transmission cycle setting unit configured to cause a transmission cycle of the self-originating OAM frame to be a predetermined transmission cycle set for a normal condition when the flow rate of the frames is greater than or equal to a predetermined threshold, and a transmission cycle calculating unit configured to calculate a transmission cycle of the OAM frame that can compensate for a shortfall in the number of the transmitted frames, the transmission cycle calculating unit being configured to cause the calculated transmission cycle to be a transmission cycle of the self-originating OAM frame when the flow rate of the frames is less than the predetermined threshold. | 05-16-2013 |
20130129738 | PHARMACEUTICAL COMPOSITION - Disclosed is an influenza virus infection inhibitor. Specifically disclosed is a pharmaceutical composition that is composed of an inhibitor such as an antibody which recognizes a peptide comprising the amino acid sequence of RERRRKKR (SEQ ID NO: 1) and inhibits the action of introducing an RR sequence into a cell. The influenza virus infection inhibitor is produced so as to contain the pharmaceutical composition. | 05-23-2013 |
20140146686 | TRANSMISSION SYSTEM, TRANSMISSION DEVICE, PACKET LOSS RATIO MEASUREMENT METHOD, AND PACKET LOSS RATIO MEASUREMENT PROGRAM - In a transmission system capable of measuring packet loss ratio between arbitrary devices upon a transmission path without increasing bandwidth of an OAM frame band, a plurality of transmission devices which have been disposed upon a transmission path are provided with a frame analysis unit which receives data frames so as to analyze the type of the data frames, a count processing unit which stores the number of received frames included in the data frames into storage module provided beforehand, an output line end portion which outputs the data frames, and an OAM processing unit which calculates the packet loss ratio in the transmission path using the number of received frames. The frame analysis unit has a function which, if the data frames are OAM frames, copies the data frames and the OAM processing unit has a function which calculates the packet loss ratio using the copied OAM frames. | 05-29-2014 |
20140341044 | DIAGNOSTIC SYSTEM - A transmission source node transmits diagnostic frames where a TTL value is set to the number of hops that is counted until an intermediate node. A relay node decrements the TTL value of the received diagnostic frames, counts the number of diagnostic frames where the decremented TTL value is 0, and recognizes continuity between the transmission source node and the relay node based on the number of transmitted diagnostic frames transmitted from the transmission source node and the number of diagnostic frames where the decremented TTL value is 0. | 11-20-2014 |
