1.  Introduction

   The Design Expectations vs. Deployment Reality in Protocol
   Development Workshop was convened by the Internet Architecture Board
   (IAB) in June 2019.  This report summarizes its significant points of
   discussion and identifies topics that may warrant further
   consideration.

   The background for the workshop was that during the development and
   early elaboration phase for a number of protocols, there was a
   presumption of specific deployment models.  Actual deployments have,
   however, often run contrary to these early expectations when
   economies of scale, Distributed Denial-of-Service (DDoS) attack
   resilience, market consolidation, or other factors have come into
   play.  These factors can result in the deployed reality being highly
   concentrated.

   This is a serious issue for the Internet, as concentrated,
   centralized deployment models present risks to user choice, privacy,
   and future protocol evolution.
