Mark Allman. Requirements for Time-Based Loss Detection, June 2020. Internet-Draft draft-ietf-tcpm-rto-consider-16.txt (work in progress).


Many protocols must detect packet loss for various reasons (e.g., to ensure reliability using retransmissions or to understand the level of congestion along a network path). While many mechanisms have been designed to detect loss, protocols ultimately can only count on the passage of time without delivery confirmation to declare a packet "lost". Each implementation of a time-based loss detection mechanism represents a balance between correctness and timeliness and therefore no implementation suits all situations. This document provides high-level requirements for time-based loss detectors appropriate for general use in the Internet. Within the requirements, implementations have latitude to define particulars that best address each situation.
