IPv6 Flow Label Specification
RFC 3697, “IPv6 Flow Label Specification”, is a Proposed Standard document published in March 2004 by J. Rajahalme, A. Conta, B. Carpenter, S. Deering. It has been obsoleted by RFC 6437 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document specifies the IPv6 Flow Label field and the minimum requirements for IPv6 source nodes labeling flows, IPv6 nodes forwarding labeled packets, and flow state establishment methods. Even when mentioned as examples of possible uses of the flow labeling, more detailed requirements for specific use cases are out of scope for this document. The usage of the Flow Label field enables efficient IPv6 flow classification based only on IPv6 main header fields in fixed positions. [STANDARDS-TRACK]
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.
