Abstract: A method, machine, and computer program product for high speed data transmission over networks by multiple data connections transmitting data in parallel having read from a data source sequentially a fixed number of blocks equal to the number of data connections in use to transmit the data. A method, machine, and computer program product for high speed data receipt from networks by multiple data connections receiving data in parallel and writing to a data target sequentially a fixed number of blocks equal to the number of data connections in use to receive the data. The purpose is to provide high speed data transfers over a network while maintaining: the same sequential order of data which was read from the data source and subsequently written to the data target, a stable and uniform transmission speed, and limited data loss in the event of a network failure.
