The RACK-TLP Loss Detection Algorithm for TCP
RFC 8985

Received changes through RFC Editor sync (created alias RFC 8985, changed title to 'The RACK-TLP Loss Detection Algorithm for TCP', changed abstract to 'This document presents the RACK-TLP loss detection algorithm for TCP.  RACK-TLP uses per-segment transmit timestamps and selective acknowledgments (SACKs) and has two parts.  Recent Acknowledgment (RACK) starts fast recovery quickly using time-based inferences derived from acknowledgment (ACK) feedback, and Tail Loss Probe (TLP) leverages RACK and sends a probe packet to trigger ACK feedback to avoid retransmission timeout (RTO) events.  Compared to the widely used duplicate acknowledgment (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.', changed pages to 29, changed standardization level to Proposed Standard, changed state to RFC, added RFC published event at 2021-02-20, changed IESG state to RFC Published)
