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.",
