Design Expectations vs. Deployment Reality in Protocol Development


A number of protocols have presumed specific deployment models during
the development or early elaboration of the protocol.  Actual
deployments have sometimes 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.


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


On occasion, the differences to expectations were almost immediate,
but they also occur after a significant time has passed from the
protocol’s initial development.


Examples include:


Email standards, which presumed many providers running in a largely
uncoordinated fashion, but which has seen both significant market
consolidation and a need for coordination to defend against spam and
other attacks. The coordination and centralized defense mechanisms
scale better for large entities, which has fueled additional
consolidation.


The DNS, which presumed deep hierarchies but has often been deployed
in large, flat zones, leading to the nameservers for those zones
becoming critical infrastructure. Future developments in DNS may see
concentration through the use of globally available common resolver
services, which evolve rapidly and can offer better security.
Paradoxically, concentration of these queries into few services
creates new security and privacy concerns.


The Web, which is built on a fundamentally decentralized design, but
which is now often delivered with the aid of Content Delivery
Networks.  Their services provide scaling, distribution, and Denial of
Service prevention in ways that new entrants and smaller systems
operators would find difficult to replicate.  While truly small
services and truly large ones may operate using only their own
infrastructure, many others are left with the only practical choice
being the use of a globally available commercial service.


Similar developments may happen with future technologies and services.
For instance, the growing use of Machine Learning technology presents
challenges for distributing effective implementation of a service
throughout a pool of many different providers.


In RFC 5218 the IAB tackled what made for a successful protocol.  In
RFC 8170, the IAB described how to handle protocol transitions.  This
workshop will explore cases where the initial system design
assumptions turned out to be wrong, looking for patterns in what
caused those assumptions to fail (e.g., concentration due to DDoS
resilience) and in how those failures impact the security, privacy,
and manageability of the resulting deployments.


While the eventual goals might include proposing common remediations
for specific cases of confounded protocol expectations, the IAB is
currently inviting papers which:


Describe specific cases where systems assumptions during protocol
development were confounded by later deployment conditions.

Survey a set of cases to identify common factors in these confounded
expectations.

Explore remediations which foster user privacy, security and provider
diversity in the face of these changes.


Important Dates


The workshop will be held June 4-5 in Helsinki, Finland.


Position papers must be submitted by May 3rd at the latest. The
program committee will review submitted position papers and send an
invitation to the workshop to one of the paper authors. Invitations
will be distributed by May 9 at the latest.


Position Paper Requirements


Interested parties must submit a brief document of one to four pages,
formatted as HTML, PDF, or plain text. We welcome papers that describe
existing work, answers to the questions listed above, new questions,
write-ups of deployment experience, lessons-learned from successful or
failed attempts, and ideally a vision towards taking deployment
considerations better in account when designing new Internet
technology. Re-submissions from work presented elsewhere are allowed.


Program Committee


The following persons are IAB contacts for this workshop:


    Jari Arkko

    Ted Hardie

    Christian Huitema

    Melinda Shore

    Brian Trammell


Position papers should be sent by email to dedr-pc@iab.org.
