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.
Note: While late in being submitted, this report is still an early
version. Comments and contributions are appreciated. We expect to
call for review of the -01 version.
The background for the workshop was that a number of protocols have
presumed specific deployment models during the development or early
elaboration of the protocol. Actual deployments have, however, often
run contrary to these early expectations when economies of scale,
DDoS resilience, market consolidation, or other factors have come
into play. These factors can result in the deployed reality being
highly concentrated.
