Subscriber and Performance Policy Identifier Context Headers in the Network Service Header
RFC 8979, “Subscriber and Performance Policy Identifier Context Headers in the Network Service Header”, is a Proposed Standard document published in February 2021 by B. Sarikaya, D. von Hugo, M. Boucadair. The canonical text is published by the RFC Editor.
Abstract
This document defines the Subscriber and Performance Policy Identifier Context Headers. These Variable-Length Context Headers can be carried in the Network Service Header (NSH) and are used to inform Service Functions (SFs) of subscriber- and performance-related information for the sake of policy enforcement and appropriate Service Function Chaining (SFC) operations. The structure of each Context Header and their use and processing by NSH-aware nodes are described.
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.
