RACK-TLP uses per-segment transmit timestamps and selective acknowledgements (SACK) and has two parts: RACK ("Recent ACKnowledgment") starts fast recovery quickly using time-based inferences derived from ACK feedback. TLP ("Tail Loss Probe") leverages RACK and sends a probe packet to trigger ACK feedback to avoid retransmission timeout (RTO) events. Compared to the widely used DUPACK threshold approach, RACK-TLP detects losses more efficiently when there are application-limited flights of data, lost retransmissions, or data packet reordering events. It is intended to be an alternative to the DUPACK threshold approach.}, }
