  • Patent number: 7986691
    Abstract: Packets out-of-sequence problem can be solved by using a window flow control scheme that can dispatch traffic at the cell level, in a round robin fashion, as evenly as possible. Each VOQ at the input port has a sequence head pointer that is used to assign sequence numbers (SN) to the cells. Also a sequence tail pointer is available at each VOQ that is used to acknowledge and limit the amount of cells that can be sent to the output ports based on the window size of the scheme. Each VIQ at the output port has a sequence pointer or sequence number (SN) pointer that indicates to the VIQ which cell to wait for. Once the VIQ receives the cell that the SN pointer indicated, the output port sends an ACK packet back to the input port. By using sequence numbers and the relevant pointers, the packet out-of-sequence problem is solved.

  • Patent number: 7986637
    Abstract: A peer-to-peer novel video streaming scheme is described in which each peer stores and streams videos to the requesting client peers. Each video is encoded into multiple descriptions and each description is placed on a different node. If a serving peer disconnects in the middle of a streaming session, the system searches for a replacement peer that stores the same video description and has sufficient uplink bandwidth. Employing multiple description coding in a peer-to-peer based network improves the robustness of the distributed streaming content in the event a serving peer is lost. Video quality can be maintained in the presence of server peers being lost. The video codec design and network policies have a significant effect on the streamed video quality. The system performance generally improves as the number of descriptions M for the video increases, which implies that a higher video quality can be obtained with the same network loading.

  • Patent number: 7965729
    Abstract: Transferring data (such as files) on an end-to-end, high-speed packet-switched network connection (a “virtual circuit”) or on a circuit. An out-of-band path is used for signaling and status messages (control). The same, or a separate, out-of-band path may be used to retransmit chunks of data that were received with errors or that were not received at all. By simplifying the data being sent over the high-speed (virtual) circuit, the resources of the (virtual) circuit are used efficiently since less overhead is required. Further, since the size of the file to be transferred can be predetermined, and since any retransmissions can be made over a path other than the (virtual) circuit, the (virtual) circuit that best meets the needs of the data transfer can be selected, thereby further increasing the efficiency with which the (virtual) circuit is used.
