Transferring data over multiple network paths using decoupled sub-flows

A non-transitory computer-readable medium storing a first set of instructions which, when executed by a processor, cause the processor to perform operations, the operations comprising:

• receiving a request for a chunk of data from an application executing on a remote device;
• splitting the chunk of data into a plurality of packets including a first packet and a second packet;
• selecting a first sub-flow to transport the first packet and a second sub-flow to transport the second packet to the remote device, wherein the first sub-flow is decoupled from the second sub-flow to the remote device;
• selecting a first stop time for the first sub-flow and a second stop time for the second sub-flow, wherein the first stop time determines when the first sub-flow will complete at the remote device and the second stop time determines when the second sub-flow will complete at the remote device, and wherein the first stop time and the second stop time are selected so that the first sub-flow and the second sub-flow are calculated to complete simultaneously at the remote device;
• transmitting the first sub-flow over a first network path of a transport layer protocol connection to the remote device;
• and
• transmitting the second sub-flow over a second network path of the transport layer protocol connection, wherein the transmitting the first sub-flow over the first network path transmits the first sub-flow from a first byte of the chunk of data going forward, and wherein the transmitting the second sub-flow over the second network path transmits the second sub-flow from a last byte of the chunk of data going backward.
