Abstract
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.
