TCP RST Diagnostic Payload

streamIETF grouptcpm stateactive pages19 rev02 expires2026-11-06 canonicalhttps://datatracker.ietf.org/doc/draft-ietf-tcpm-rst-diagnostic-payload/
This document specifies an experimental diagnostic payload format returned in TCP RST segments. Such payloads are used to share with an endpoint the reasons for which a TCP connection has been reset. Sharing this information is meant to ease diagnostic and troubleshooting. This specification builds on provisions that are already present in RFC 9293 "Transmission Control Protocol (TCP)". As such, this document does not require any change to RFC 9293.
