Abstract:
   This document standardizes both 1) a means of requesting a stream of
   packet samples from any device generating, routing, or forwarding
   traffic, and 2) receiving metadata information from the network
   element about these packet samples, and the structure of said stream
   metadata.  A main design requirement is to provide network elements
   with widely varying capabilities (e.g., ASICs, NPUs, NICs, vSwitches,
   CPUs) a mechanism to sample and export packets at high rates, by
   allowing communication of the specific bit formats of internal data
   headers applied to the packet flow, in a way that enhances
   interoperability between traffic sources and sinks.  Historically,
   Netflow and similar mechanisms have been used for these use cases;
   however, the increasing packet rates of very high-speed devices and
   increasing variance in the information available to data planes lends
   itself to both a less-prescriptive set of packet formats as well as a
   decoupling of the sampling action from the collection and analysis
   mechanisms.
