20110299424 | SWITCHING APPARATUS AND METHOD FOR SETTING UP VIRTUAL LAN - A switching apparatus having a plurality of ports, includes: switch information storage to store an output port identifier for a combination of an input port identifier, an input virtual path identifier, and a destination address; a detector to detect a first input virtual path identifier and a first destination address assigned to an input packet; a searcher to search the switch information storage for a first output port identifier based on a first input port identifier that identifies a port to which the input packet has been input, the first input virtual path identifier, and the first destination address; and a packet switch to transfer the input packet to a port identified by the first output port identifier. | 12-08-2011 |
20120275325 | COMMUNICATION APPARATUS AND METHOD - In a communication apparatus, based on the relationship among a first port for outputting frames including tag information, a frame destination address, and bandwidth specified to the first port, a controller generates threshold value information to be associated with a second port to which the frames including tag information are input. With respect to the frames input from the second port, a reception processor measures a reception rate according to the tag information and the frame destination address, and selects, based on the reception rate and the threshold value information, frames to be preferentially discarded at the first port. | 11-01-2012 |

20120314579 | COMMUNICATION SYSTEM AND COMMUNICATION APPARATUS - A communication system includes a first communication apparatus including one or more first processors that determine a first bandwidth variance for each flow, based on a requested bandwidth variance amount and a surplus bandwidth of a physical line, and a first transmitter that transmits the first bandwidth variance to an adjacent apparatus; and a second communication apparatus including one or more second processors that set the received first bandwidth variance as a requested bandwidth variance amount for the second communication apparatus and determine a second bandwidth variance for each flow from the first bandwidth variance and the surplus bandwidth, and a second transmitter that transmits the second bandwidth variance to an adjacent apparatus. | 12-13-2012 |
20130182720 | FRAME CONCATENATION APPARATUS - A frame concatenation apparatus includes a storage unit to store a plurality of frames to be transmitted, a generation unit to generate a concatenated frame including the plurality of frames read out from the storage unit and serially concatenated, and including frame length information on each frame attached thereto, and an attachment unit to attach information for establishing synchronization with a receiver of the concatenated frame, to the concatenated frame. | 07-18-2013 |
20130315065 | APPARATUS AND METHOD FOR CONTROLLING CONGESTION IN A COMMUNICATION NETWORK - An apparatus controls congestion in a communication network. The apparatus includes a plurality of ports configured to transmit and receive frames. The apparatus stores a traffic volume of each of the plurality of ports. The apparatus detects congestion in the communication network, based on frames that are received via the plurality of ports. Then, the apparatus determines one or more ports that receive frames causing the detected congestion, based on the traffic volumes of the plurality of ports. | 11-28-2013 |
20140347975 | DATA TRANSMITTING DEVICE, DATA TRANSMITTING METHOD AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM - A data transmitting device coupling to a plurality of nodes in a network includes a plurality of communication paths, the data transmitting device includes a memory and a processor coupled to the memory configured to set a routing table based on a command that designates a first communication path included in the plurality of communication paths, to detect a link failure occurred in the network, and when the link failure has occurred at a first location between the data transmitting device and a first node adjacent to the data transmitting device on the first communication path, to modify the routing table so that data are to be transmitted to a second node on a second communication path different from the first communication path, and when the link failure has occurred at a second location that differs from the first location in the network, to maintain the routing table. | 11-27-2014 |
