    • In a data transfer method and system for networks having gateway-mediated asymmetric transport, data and feedback channels are established between sender and receiver, along with a gateway feedback channel between gateway and sender. Cohorts of datagrams are transformed using fault-tolerant coding to create chapters whose size correspond to the asymmetric transport's timing. The sender transmits chapters in chunks at a rate to keep the gateway at an optimum fill for maximal throughput without transmit-end packet drops. The receiver reconstructs complete cohorts of original datagrams from a received subset of the transformed datagrams. The receiver acknowledges successfully recovered cohorts and identifies missing or corrupt datagrams of a chapter whenever recovery is unsuccessful. The sender resends sufficient lost datagrams to allow cohort recovery. The sender self-tunes its transmission rate based upon gateway fill, network latency and datagram loss rate to keep datagram loss rate below an upper bound.
    • 在具有网关介导的非对称传输的网络的数据传输方法和系统中,在发送方和接收方之间建立数据和反馈信道以及网关与发送方之间的网关反馈信道。 使用容错编码来转换数据报组,以创建大小对应于不对称传输时序的章节。 发送者以块的速率发送章节,以保持网关处于最佳填充的最佳吞吐量,而没有发送端分组丢弃。 接收机从接收到的转换数据报的子集重建原始数据报的完整队列。 接收器确认成功恢复的队列,并在恢复失败时识别章节的丢失或损坏的数据报。 发送者重新发送足够的丢失数据报,以允许队列恢复。 发送方根据网关填充,网络延迟和数据报丢失速率自动调整传输速率,以保持数据报丢失率低于上限。

    • A method and system are provided for data transfer in a network where jamming conditions may occur. A sender at a first endpoint of the network includes a processor that implements fault-tolerant coding of cohorts of original datagrams that are converted into corresponding chapters of transformed datagrams such that the original datagrams are recovered by a receiver at a second endpoint of the network from a subset of the transformed datagrams of each chapter transferred over the network. In the presence of jamming, chapter size and redundancy of the coding are adjusted according to the level of jamming to enable datagram recovery with a minimum of resending over the network. The sending rate may also be tuned in reaction to changing network conditions based on messages from the receiver on a separate feedback channel to keep datagram loss rates below a specified upper bound.

    • A data transfer method and system are provided for networks having gateway-mediated asymmetric transport. Separate data and feedback channels are established between sender and receiver units, along with a gateway feedback channel between a gateway and the sender. The sender transmits datagrams to the gateway in temporal chunks corresponding to the asymmetric transport's timing to keep the gateway's buffer at an optimum fill for maximal throughput without transmit-end packet drops. The receiver acknowledges those datagrams that have been successfully received and identifies any missing or corrupt datagrams. At least some messages include timing information indicative of network latency and congestion. The sender resends datagrams identified as missing or corrupt. The sender self-tunes its transmission rate in reaction to changing network conditions, based upon gateway buffer fill, network latency and datagram loss rate to keep datagram loss rate below a specified upper bound.
