Operating the Network Service Header with Next Protocol "None"

Overview

RFC 8393, “Operating the Network Service Header with Next Protocol "None"”, is a Proposed Standard document published in May 2018 by A. Farrel, J. Drake. The canonical text is published by the RFC Editor.

Abstract

This document describes a network that supports Service Function Chaining (SFC) using the Network Service Header (NSH) with no payload data and carrying only metadata. This is achieved by defining a new NSH "Next Protocol" type value of "None".

This document illustrates some of the functions that may be achieved or enhanced by this mechanism, but it does not provide an exhaustive list of use cases, nor is it intended to be definitive about the functions it describes. It is expected that other documents will describe specific use cases in more detail and will define the protocol mechanics for each use case.

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.
