EFFICIENT MECHANISM FOR THE TRANSMISSION OF MULTIPATH DUPLICATE PACKETS

The method, in some embodiments, aggregates duplicate transmission control protocol (TCP) packets of a data stream duplicated and sent over disjoint routing paths. Each duplicate pair of packets includes a packet sequence number unique to that duplicate pair. The method iteratively (1) generates a w...

Zusammenfassung:The method, in some embodiments, aggregates duplicate transmission control protocol (TCP) packets of a data stream duplicated and sent over disjoint routing paths. Each duplicate pair of packets includes a packet sequence number unique to that duplicate pair. The method iteratively (1) generates a window of packet sequence numbers for the data stream starting with a lowest packet sequence number, of the data stream, that has not been received, (2) receives a TCP packet sent over one of a first routing path and a second, disjoint routing path. If the packet sequence number of the received TCP packet is outside the window or is a duplicate of a previously received TCP packet, the method drops the received TCP packet. If the packet sequence number of the received TCP packet is within the window and is not a duplicate of a previously received TCP packet, the method stores the received packet.
