  • Patent number: 10554545
    Abstract: In a method for data transmission in a communications network, data frames containing metadata and payloads are transmitted via point-to-point connections between a respective transmitter and a receiver according to a communications protocol. For each point-to-point connection, a transmission list of the data frames to be transmitted from the transmitter to the receiver is kept. In addition, a priority set of at least three interrupt priorities of pairs with differing significance is provided, and the communications protocol permits each data frame of a transmission list to be assigned an interrupt priority and to interrupt a current transmission of a data frame of the transmission list in order to transfer a data frame that is contained in the transmission list and that has been assigned a higher interrupt priority than the currently transferred data frame.

  • Patent number: 10554571
    Abstract: A stream at a source device may be transmitted over multiple channels. At the input of the channels the packets from the stream may be grouped into chunks. Informational packets may be appended to the chunks. The informational packets may include sequencing information for the chunks and packet-to-packet timing information. The chunks may then be distributed over the multiple channels. After transmission over the channels, the informational packets may be extracted from the chunks. Reconstruction circuitry, at the destination device, may determine the sequence of the chunks at the source device based on the sequencing information. The reconstruction circuitry may also determine relative timings of the packets within the single stream based on the packet-to-packet timing information. The packets may be released from buffers in accord with the determined packet-to-packet timing information and the sequencing information to recreate the relative timings within the single stream at the destination device.
