It has been obsoleted by RFC 9293 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document clarifies the Zero Window Probes (ZWPs) described in RFC 1122 ("Requirements for Internet Hosts -- Communication Layers"). In particular, it clarifies the actions that can be taken on connections that are experiencing the ZWP condition. Rather than making a change to the standard, this document clarifies what has been until now a misinterpretation of the standard as specified in RFC 1122. This document is not an Internet Standards Track specification; it is published for informational purposes.
What “Informational” means
Published for the general information of the community. It does not define an IETF standard and carries no standards-track status.
