Publication number: 20070165633Abstract: When multicast distribution is performed on a network where a point-to-point connection is made between user terminals and a multicast router, the multicast router is protected from load due to response reports, join requests, or leave statements sent from the user terminals simultaneously. If the user terminals send response reports simultaneously, a Layer 2 switch disposed between the user terminals and the multicast router limits response reports sent to the multicast router. The Layer 2 switch prevents response reports sent from the same user terminal from being discarded consecutively, by sending a response report sent from the same user terminal to the multicast router 200 with priority in the next join confirmation event. If the user terminals send join requests or leave statements simultaneously, the Layer 2 switch limits the join requests or leave statements sent to the multicast router 200 in the same manner.Type: ApplicationFiled: August 23, 2006Publication date: July 19, 2007Inventors: Kozo Ikegami, Takashi Yokoyama, Minoru Nagai, Yoshitaka Sakamoto, Shigehiro Onizawa

Publication number: 20070165635Abstract: The invention is related with network communication, in particular wireless networking. In order to improve bandwidth utilization, a header compression protocol is implemented in most wireless network systems, such as robust header compression ROHC for WLAN systems. When using multicast groups for data communication problems with ROHC are related with relative late initiation of stations that newly enter the multicast group. The invention proposes an improved state machine for the compressor in order to overcome this drawback. It is also proposed an improvement for the decompressors which omit sending positive acknowledgements in order to further improve compression efficiency. The invention also concerns an accordingly improved method for the exchange of data packets in a network of distributed stations.Type: ApplicationFiled: January 12, 2007Publication date: July 19, 2007Inventors: Zhi Gang Zhang, Huan Qiang Zhang, Charles Chuanming Wang

Publication number: 20070165668Abstract: A communications system and method enables delivery of packets over network boundaries while preserving the QoS bits configuration. The communications system includes at least one sending site configured to send the packet. The packet may have a first set of bits in a first bit-set location that indicates an intended packet forwarding priority of the packet. A data network is included that has a traffic class identification. The data network associates the packet forwarding priority with the traffic class identification and writes a second set of bits into the first bit-set location of the packet based on the traffic class identification. The second set of bits indicates a delivery priority that corresponds to the packet forwarding priority. The packet is forwarded based on at least one of the packet forwarding priority and the delivery priority, wherein the delivery priority is based on the data traffic class identification.Type: ApplicationFiled: January 13, 2006Publication date: July 19, 2007Inventor: Chia Liu

Publication number: 20070165669Abstract: A unified architecture for a multipoint VC session and interactive broadcasting system is provided that includes a server, one or more video accessing points, reflectors and client machines. The server sets up the video communication sessions (VC sessions), each of which is hosted by one video accessing point. The server downloads the A/V client software to client machines. Reflectors direct audio/visual signals to client machines. The reflectors are coupled to the video accessing point and receive a control signal from the video accessing point in order to direct the A/V signals from the client machines participating in the VC session. The client machines process all of the A/V signals. This system for distributing the VC session tasks across these components reduces any bottleneck effect from using a single, central control point to direct the VC session and route the A/V signals.Type: ApplicationFiled: December 19, 2006Publication date: July 19, 2007Inventor: Leonid Kasperovich

Publication number: 20070165670Abstract: A combination-information creating unit creates combination information for determining a maximum number of combinations or a maximum frame length according to a usable radio band and a modulation method and combination possibility information for indicating that a combination of frames is possible. A frame combining unit combines a plurality of frames received from an outside access line, based on the combination information, the combination possibility information, and predetermined packet information. A frame dividing unit divides a combined frame included in a received radio signal into individual frames.Type: ApplicationFiled: June 3, 2004Publication date: July 19, 2007Inventors: Yukimasa Nagai, Akinori Fujimura, Hiroaki Hirai, Hiroyoshi Suga

Publication number: 20070165671Abstract: A method and device are described for determining an error rate during transmission from a transmitter/receiver station to a transmitter/receiver device and a measuring device. A first data block and at least one other and different redundant block is received by the transmitter/receiver device, decoded, and checked for transmission errors. If an error is ascertained in the first data block, another redundant block is requested, but in response the first data block is retransmitted instead.Type: ApplicationFiled: March 4, 2004Publication date: July 19, 2007Inventors: Ralf Plaumann, Max Winkhofer, Johannes Fassrainer

Publication number: 20070165672Abstract: A mechanism for performing remote direct memory access (RDMA) operations between a first server and a second server. The apparatus includes a packet parser and a protocol engine. The packet parser processes a TCP segment within an arriving network frame, where the packet parser performs one or more speculative CRC checks according to an upper layer protocol (ULP), and where the one or more speculative CRC checks are performed concurrent with arrival of the network frame. The protocol engine is coupled to the packet parser. The protocol engine receives results of the one or more speculative CRC checks, and selectively employs the results for validation of a framed protocol data unit (FPDU) according to the ULP.Type: ApplicationFiled: February 17, 2006Publication date: July 19, 2007Applicant: NetEffect, Inc.Inventors: Kenneth Keels, Brian Hausauer, Vadim Makhervaks, Eric Schneider

Publication number: 20070165673Abstract: The present invention provides methods for reconstructing lost or corrupted packets. One embodiment of the method may include performing at least one parity operation on information associated with at least one first packet. The method may also include transmitting the information associated with at least one first packet and information indicative of the at least one parity operation. Another embodiment of the method may include accessing information associated with at least one first packet and information indicative of at least one parity operation performed on information associated with at least one first packet and at least one second packet. The method may also include determining information associated with the at least one second packet based on information associated with at least one first packet and information indicative of at least one parity operation performed on information associated with at least one first packet and the least one second packet.Type: ApplicationFiled: March 2, 2006Publication date: July 19, 2007Inventor: Dawei Huang

Publication number: 20070165674Abstract: Apparatuses and methods are provided for transmitting and receiving uncompressed audio or video (AV) data by applying a different coding rate to each bit or each group of bits included in the uncompressed AV data according to significance of each bit or each group of bits. The apparatus for transmitting the uncompressed AV data includes a grouping unit which classifies bits of each pixel included in the uncompressed AV data into at least two groups of bits according to a significance of the bits; an encoding unit which performs error correction encoding on each of the at least two groups using a different coding rate; and a radio frequency (RF) processing unit which transmits the encoded, uncompressed AV data, which includes the pixels on which the error-correction encoding was performed, using a communication channel.Type: ApplicationFiled: January 9, 2007Publication date: July 19, 2007Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Ji-sung Oh, Joong-suk Park, Yeon-woo Lee, Jung-Won Kwak, Sung-wook Cha
