1. A method for sending a data stream from a sending endpoint to a receiving endpoint, wherein both of the sending endpoint and the receiving endpoint each have multiple physical interfaces connecting the sending endpoint and the receiving endpoint to multiple networks, respectively, and the data stream is split into a series of data packets and sent over the multiple physical interfaces, the method comprising:

  • determining an expected difference in arrival time between data packets sent concurrently over different ones of the multiple physical interfaces and received at the receiving endpoint;

    sending a next available data packet of the series over a fastest one of the multiple physical interfaces, wherein the fastest one of the multiple physical interfaces is determined based on the determined expected difference in arrival time; and

    extracting a data packet from further back in the series of data packets in accordance with the determined expected difference in arrival time, and sending the extracted data packet on a corresponding slower one of the multiple physical interfaces,wherein the next available data packet is sent from the sending endpoint nearly simultaneously as the extracted data packet is sent from the sending endpoint.
