| 20090059924 | PACKET TRANSMITTING METHOD, RELAY NODE AND RECEIVING NODE - A packet transmitting method wherein an explicit multicast packet can be transmitted with the consumption of communication bands of broadcast media being suppressed. According to this method, a link level multicast is used to transmit an explicit multicast packet only to next hop nodes that, even when receiving the explicit multicast packet through the link level multicast, will not output the same packet to the broadcast media, while a unicast is used to transmit an explicit multicast packet to the other next hop nodes. | 03-05-2009 |
| 20090116482 | MULTICAST DISTRIBUTION DEVICE AND MULTICAST DISTRIBUTION METHOD - Provided is a multicast distribution device for transmitting a packet in which a reception node can easily perform signal synchronization between a plurality of hierarchized data. The multicast distribution device ( | 05-07-2009 |
| 20090245252 | COMMUNICATION TERMINAL AND RETRANSMISSION REQUEST METHOD - A multicast communication system in which a receiving node which has detected a packet loss can make a retransmission request without applying a high load to a transmitting node, all receiving nodes, and the band of the entire network. The transmitting node transmits an explicit multicast data packet including an address list including a plurality of destination addresses and a bitmap indicating whether the data packet has been delivered to the respective destination addresses, to a plurality of the receiving nodes. The receiving node which has detected the packet loss checks an address list and bitmap of another data packet received and selects a receiving node to which the another data packet has been delivered as a retransmission requester. The receiving node which has detected the packet loss creates a unicast retransmission request packet with the selected receiving node as the destination and transmits it to the selected receiving node. | 10-01-2009 |
| 20110002333 | TERMINAL AND N-TREE CONSTRUCTING METHOD - A terminal apparatus is provided that minimizes traffic congestion by reducing end-to-end delay and maximizes the bandwidth available in shared N-tree ALM nodes. In this terminal apparatus, an optimal stream path information table ( | 01-06-2011 |
| 20110002334 | COMMUNICATION TERMINAL AND COMMUNICATION STATE CHANGE METHOD - A generating unit ( | 01-06-2011 |
| 20110064079 | COMMUNICATION CHANNEL BUILDING DEVICE AND N-TREE BUILDING METHOD - Disclosed is a communication channel building device which can guarantee a fair bandwidth allocation and exhibit a preferable perception AV quality in an ALM application. A transfer table building controller ( | 03-17-2011 |
| 20110110260 | STREAMING COMMUNICATION DEVICE, STREAMING COMMUNICATION METHOD, AND STREAMING COMMUNICATION SYSTEM - A streaming communication device which accurately estimates a packet which will be lost in the future. A streaming communication device which transmits or receives a stream via a router over a packet-switched network, the streaming communication device including: an accumulating unit ( | 05-12-2011 |
| 20110128958 | APPLICATION LAYER MULTICAST (ALM) TREE CONSTRUCTING APPARATUS, ALM TREE CONSTRUCTING METHOD, PROGRAM, AND INTEGRATED CIRCUIT - The ALM tree constructing apparatus ( | 06-02-2011 |
