     Requirements for Interactive Query with Dynamic Network Probes
                      draft-song-opsawg-dnp4iq-01

Abstract

   This document discusses the motivation and requirements for
   supporting interactive network queries and data collection through a
   mechanism called Dynamic Network Probes (DNP).  Network applications
   and OAM have various data requirements from the data plane.  The
   unpredictable and interactive nature of the query for network data
   analytics asks for dynamic and on-demand data collection
   capabilities.  As user programmable and configurable data plane is
   becoming a reality, it can be extended to support interactive query
   through DNPs.  DNP supports node, path, and flow-based data
   preprocessing and collection.  For example, in-situ OAM (iOAM) with
   user-defined flow-based data collection can be programmed and
   configured through DNP.  DNPs serve as a building block of an
   integrated network data telemetry and analytics platform which
   involves the network data plane as an active component for user-
   defined data collection and preparation.

1.  Introduction

   Network service provider's pain points are often due to the lack of
   network visibility.  For example, network congestion collapse could
   be avoided in many cases if it were known exactly when and where
   congestion is happening or even better, if it could be precisely
   predicted well before any impact is made; sophisticated network
