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.

Abstract: As part of managing delivery of a given packet flow according to a reliable transport protocol, a sender sends, to a receiver, a last flow packet among multiple flow packets of a flowlet. After sending the last flow packet but before satisfaction of a timeout condition for the last flow packet, the sender sends one or more end-of-flowlet (“EOF”) packets, which can be flush packets, query packets, or another type of packet. The sender receives, from the receiver, feedback metadata for the EOF packet(s) and updates a tracking window based at least in part on the feedback metadata. The sender selectively resends one or more unacknowledged flow packets according to the updated tracking window. In this way, the sender can quickly address any dropped packets or significantly delayed packets at the end of a flowlet, without waiting for the timeout condition to detect the dropped or delayed packets.
