An Update to the tcpControlBits IP Flow Information Export Information Element
RFC 9565, “An Update to the tcpControlBits IP Flow Information Export Information Element”, is a Proposed Standard document published in March 2024 by M. Boucadair. It obsoletes RFC 7125. The canonical text is published by the RFC Editor.
Abstract
RFC 7125 revised the tcpControlBits IP Flow Information Export (IPFIX) Information Element that was originally defined in RFC 5102 to reflect changes to the TCP header control bits since RFC 793. However, that update is still problematic for interoperability because some flag values have subsequently been deprecated.
This document removes stale information from the IANA "IPFIX Information Elements" registry and avoids future conflicts with the authoritative IANA "TCP Header Flags" registry.
This document obsoletes RFC 7125.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
