Abstract
As part of managing delivery of a packet flow according to a reliable transport protocol that supports multi-path delivery, a sender splits data into multiple flow packets of a flow and sends at least some of the flow packets to a receiver on multiple paths of a network. The sender receives feedback metadata and updates an out-of-order ('OOO') tracking window. The sender also determines a metric that quantifies degree of OOO delivery. In general, the metric measures the extent to which flow packets have been successfully delivered OOO after a “missing” flow packet. If a sufficient count or range of flow packets have been acknowledged as received OOO after the missing flow packet, the missing flow packet is likely to have been dropped—not merely delayed. Depending on the metric, the sender selectively resends to the receiver one or more unacknowledged flow packets.
