Abstract:

   Network measurement supports management applications that need
   statistics about both large and small flows.  Sketch-based techniques
   use compact data structures and are effective for large flows, but
   hash collisions can produce substantial relative errors for small
   flows.  In-band Network Telemetry (INT) can provide detailed
   observations for individual packets, but applying it to every packet
   can consume significant packet, bandwidth, and collector resources.

   This document describes a framework that uses sketches for large
   flows and INT for small flows.  It also describes measurement-point
   selection when exact routing information is unavailable and
   congestion-aware collection of sketch and INT reports.  The document
   identifies the information needed to describe and compare
   implementations.  It does not define a new packet format, INT
   instruction, sketch algorithm, or routing protocol.

   As a concrete applicability direction, the document considers time-
   variant non-terrestrial networks (NTNs), in which paths and available
   forwarding resources can change over time.  It maps the existing
   Sketch-INT framework to this scenario and identifies the assumptions
   that require validation.  It does not claim that the existing
   terrestrial implementation has been deployed or evaluated on
   satellite hardware.
