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.
For the definition of Status, see RFC 2026.
