Abstract

   This draft describes a method of inserting Key Performance Indicators
   (KPIs) into Network Service Header (NSH) encapsulated packets or
   frames on service chains. This method may be used to monitor latency
   and QoS configuration to identify problems with virtual links
   (vlinks), Virtual Network Functions (VNFs) or Physical Network
   Functions (PNFs) on the Rendered Service Path (RSP).
