Network Service Header
RFC 8300, “Network Service Header”, is a Proposed Standard document published in January 2018 by P. Quinn, U. Elzur, C. Pignataro. It has since been updated by RFC 9451. The canonical text is published by the RFC Editor.
Abstract
This document describes a Network Service Header (NSH) imposed on packets or frames to realize Service Function Paths (SFPs). The NSH also provides a mechanism for metadata exchange along the instantiated service paths. The NSH is the Service Function Chaining (SFC) encapsulation required to support the SFC architecture (defined in RFC 7665).
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.
