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.
This document is a product of the Service Function Chaining Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
