Network Service Header Metadata Type 2 Variable-Length Context Headers
RFC 9263, “Network Service Header Metadata Type 2 Variable-Length Context Headers”, is a Proposed Standard document published in August 2022 by Y. Wei, U. Elzur, S. Majee, C. Pignataro, D. Eastlake 3rd. The canonical text is published by the RFC Editor.
Abstract
Service Function Chaining (SFC) uses the Network Service Header (NSH) (RFC 8300) to steer and provide context metadata (MD) with each packet. Such metadata can be of various types, including MD Type 2, consisting of Variable-Length Context Headers. This document specifies several such Context Headers that can be used within a Service Function Path (SFP).
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.
