摘要： Embodiments herein disclose conditioning traffic through multiple data paths of a Software-Defined Wide Area Network (SD-WAN). Some embodiments include monitoring available paths through an SD-WAN to reach a destination node, determining a quality score for packets to the destination node on a first path of the available paths, sending a data packet sequence to the destination node on the first path, generating a forward error correction (FEC) packet for the packet sequence, and sending the FEC packet to the destination node on a second path of the available paths in response to the quality score being less than a quality threshold.

摘要： A data transmission method, device, and system to resolve a problem that encoding cannot be performed based on an incomplete subframe because a length of the incomplete subframe is unknown. A first device generates a first subframe and a second subframe according to first data, determines a redundancy version (RV) of the first subframe according to an RV of the second subframe, and sends M of N orthogonal frequency division multiplexing (OFDM) symbols of the first subframe and N OFDM symbols of the second subframe to a second device.

摘要： A first communication node (110) receives a stream of code blocks from a second communication node (120) over an acknowledged connection (131.). The first communication node processes the received code blocks in accordance with at least one transport format parameter, TFP, detects errors in received code blocks, and transmits an acknowledgment in respect of groups of code blocks indicating whether at least one error was detected in the group. A first subset of the code blocks of a group are transmitted (e.g., modulated and demodulated) in accordance with a first TFP value, and a remainder of the code blocks are transmitted in accordance with a second TFP value. Because the first and second TFP values are independent, it is possible either to shorten the necessary processing time in the first communication node or, in connection with a predictive acknowledgment mechanism, to make the receiving-side processing of code blocks that do not contribute to the value of the transmitted acknowledgment more robust.

摘要： In general, the subject matter described in this specification can be embodied in methods, systems, and program products for adaptive data unit transmission. A sliding window is filled with data units and designates a sliding window start position and a sliding window end position. A value for each of the data units in the sliding window is stored, the value representing a maximum number of times that each data unit is to be transmitted. The stored value is different among at least two of the data units. Data units are selected from the sliding window to be assembled into a packet. An assembled packet is transmitted to a receiving computerized device. A determination that the data unit positioned at the sliding window start position has been transmitted a maximum number of time is performed, and in response a different data unit is positioned at the sliding window start position.
