The IESG has received a request from the TCP Maintenance and Minor Extensions WG (tcpm) to consider the following document: - 'The RACK-TLP loss detection algorithm for TCP' <draft-ietf-tcpm-rack-13.txt> as Proposed Standard
The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the [email protected] mailing lists by 2020-11-30. Exceptionally, comments may be sent to [email protected] instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document presents the RACK-TLP loss detection algorithm for TCP. 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. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-tcpm-rack/ No IPR declarations have been submitted directly on this I-D. _______________________________________________ IETF-Announce mailing list [email protected] https://www.ietf.org/mailman/listinfo/ietf-announce
