Decentralization of the Internet Research Group at IETF-117

The Decentralization of the Internet Research Group (DINRG) of the Internet Research Task Force (IRTF) had a meeting on 2023-07-27 at the 117th meeting of the Internet Engineering Task Force (IETF). DINRG aims to provide for the research and engineering community, both an open forum to discuss the Internet centralization phenomena and associated potential threats, and a platform to facilitate the coordination of efforts in identifying the causes of observed consolidations and the mitigation solutions.

For context, we recently published a workshop report that discusses some fundamental problems: ACM SIGCOMM CCR: Report of 2021 DINRG Workshop on Centralization in the Internet

The DINRG meeting at IETF-117 meeting featured three highly interesting talks by Cory Doctorow, Volker Stocker & William Lehr, and Christian Tschudin that created quite some attention and led to lively discussions during and after the meeting. There is a full meeting recording on youTube, and we have published meeting minutes. Special thanks to Ryo Yanagida, A.J. Stein, and Eve Schooler for taking notes at the meeting.

Cory Doctorow: Let The Platforms Burn: Bringing Back the Good Fire of the Old Internet

Cory Doctorow, a science fiction author, activist and journalist, talked about a trend in platform evolution that he calls enshittification, where platforms go through different phases after growing user bases quickly as per platform economics and market domination strategies and of locking in users through technical and economic barriers. In advertisement (and digital online market) platforms, the platform operator sits between the users and other companies (so-called "two-sided market" scenarios), where the user base, the obtained personal information and behavioral surveillance results become assets to attracts such companies.

For example, in order to make avertising more effective, social media platforms would increase control of users's timelines, i.e., content that is presented to them, and make it harder for users to leave the platform. Overall this results in negative user experience. For increasing advertisment revenue, platforms would then sell attention more directly, i.e., exploit their position in the advertisement market. See Cory's posting on enshittification for details.

This process and the difficulties in effectively controlling and regulating platform companies, has led to a permanent crisis that Cory compares to a fire hazard situation. Platforms were rocked by scandals private data theft, accidental leaks and intended data sharing with other insitutions etc.

While the computer and networking world has seen a constant emerging and vanishing of "platforms" (operating systems, PC companies, online services) before, the current concentrated tech market makes is impossible to let harmful (or not very user-friendly) dissolve. This is due to network effects (Metcalfe's law) and switching costs, for example when trying to leave a dominant social media platforms and thereby losing connections to friends. This monopoly situation is enabled by a legal environment with ineffective antitrust laws, which has allowed for dominating platform to constantly acquire competing companies and potentially disruptive businesses.

With new laws for content moderation and censorship, platform get even more control over their users (in the name of preventing harrassment), without making in any easier to leave platforms. In his article (and podcast epsidode) called "Let the Platforms Burn", Cory concluded

Platforms collapse "slowly, then all at once." The only way to prevent sudden platform collapse syndrome is to block interoperability so users can't escape the harms of your walled garden without giving up the benefits they give to each other.

We should stop trying to make the platforms good. We should make them gone. We should restore the "good fire" that ended with the growth of financialized Big Tech empires. We should aim for soft landings for users, and stop pretending that there's any safe way to life in the fire zone.

We should let the platforms burn.

WIth respect to the (de-)centralization discussion in DINRG and the Internet community, this raises some important question as to

  • what is the role of open interfaces, standards etc today in reality? Are we still using them to build interoperable, possibly federated systems?
  • how should technology development, standards setting and regulation evolve to effectively enable user choice (migration, platform selection)?


There was a question whether the real issue was that platforms are making a remarkable griphold, buying each other, but they are buying the users, i.e., whether the primary concern is the size of these platforms with this method or the method itself only? Cory replied in saying that size certainly promotes distortions. Scale was problem for two reasons. The contract enforcement function dominates. When the referee is less powerful than the team, it allows teams to cheat.
Secondly, even if we stipulated that companies are well run by smart people, they all make errors, and at that scale the mistakes are much more consequential.

Another question was who is willing to implement the interoperability standards and how companies can be convinved to do that. Cory talked about companies' motivation, i.e., companies wanted walled gardens, or to have APIs with advantages (vs disadvantages) to them. What they really seeked (over competitive interoperability) was to have legal remedies for those who reverse engineer to competitively enter the market. When there was a mandate and permission for inter-operators, if restoring that power was possible, that would help to avoid unquantifiable risk.

Some of these strategies are discussed in Cory upcoming book "How to seize the means of computation”.

Volker Stocker and William Lehr: Ecosystem Evolution and Digital Infrastructure Policy Challenges: Insights & Reflections from an Economics Perspective"

Volker Stocker of the Weizenbaum Institute for the Networked Society and William Lehr of the Advanced Networking Architecture Group in CSAIL at MIT presented their research on ecosysem evolution and policy challenges from an economics perspective. Volker is an economist with broad experience in interdisciplinay research, and William is a telecommunications and Internet economist and consultant.

Volker talked about the convergence of digital and non-digital worlds and mentioned a few trends that needed attention:

  • The shift to the edge and shift to the localization of traffic.
  • Ownership and management has shifted in the Internet ecosystem: sometimes hyper giant content providers with proprietary networks, sometimes edge clouds or roving resources.
  • Potential consequences: value chain constellations are more complex, diverse & dynamic, resulting in changing ownership and governance structures, industry structures as well as competititve and innovational dynamics.

Volker made three points in his reflections on ecosystem evolution:

  1. Essential digital infrastructure is about more than connectiivty, not just connectivities like IPX and ISPs.
  2. The majority of the requisite investmenet will be private! E.g., access ISPs, CAPs, CDNs, upstream ISPs, and end-users are all investing.
  3. More and new forms of resource sharing will be needed. More network sharing agreements: active & passive sharing arrangements and optimal models are evolving.

William highlighted that the legacy Internet is not the Internet of today, and the economics of yesterday are not those of today. One of the questions is how to restore meaningful competition?

He mentioned the following challenges and paths forward:

  1. Multidisciplinary Engagement & Feedback
  2. Assymetric Info & Measurements: Metrics and data (and their provenance)
  3. Capacity to Detect and Act


There was a discussion about how the private sector is expected to profit from the infrastructure development needed by society (assuming investments from the private sector). William replied in saying that
government built/subsidized most infrastructure in most places, with small investments needed initially. Some say significant investment should come from the utilities, which we should not dismiss. But we likely will need a strong argument on how to get there. Either we say there is a lot of money coming from public sector (for example, through taxes) or we have to find a way to manage private actors. Thus policy issues are important. Some of these questions are discussed in Williams paper on "Getting to the Broadband Future Efficiently with BEAD funding”.

Another question alluded to policy lagging behing the technical development, i.e., the mismatch of speed of innovation and speed of regulation (which is really hard at the national and internationl levels). William said that the best hope is standards and architectures that provides options and mentioned the importance of open source software.

Christian Tschudin: Minimal Global Broadcast

Christian Tschudin of the University of Basel presented a research idea called "Minimal Global Broadcast" (abstract). Christian is a computer science professor with a track record of research in Information-Centric Networking, distributed computing, and decentralized systems.

Christian started out from the observation that contacting peers in a decentralized environment is challenging. The key question is how do you learn about a peer’s current coordinates and their preferences? The platforms themselves often offer directories, but these are logically centralized rendezvous servers with a partial view and require trust in these platforms. Instead of conceptualizing an uber directory service Christian proposed a global information dissemination system that focuses on the data, asserting an allowance of “200 bytes of novelty per month
and citizen”.

This global broadcast channel can (and should) be implemented in many ways, starting from sneakernets to shortwave communication and including Internet-based online-services. Christian explained how such a service could be used to facilitate user migration and user discovery on their current preferred platform(s).


There were some question on trust in user identities. Christian said that trust roots would be external to MGB, and that there would be different levels of trust, e.g., for inter-personal relationship vs. business relationships.

ACM SIGCOMM CCR: Report of 2021 DINRG Workshop on Centralization in the Internet

without comments

ACM SIGCOMM CCR just published the report of our 2021 DINRG meeting on Centralization in the Internet.

Executive Summary

There is a consensus within the networking community that the Internet consolidation and centralization trend has progressed rapidly over recent years, as measured by the structural changes to the data delivery infrastructure, the control power over system platforms, application development and deployment, and even in the standard development efforts. This trend has brought impactful technical, societal, and economical consequences.

When the Internet was first conceived as a decentralized system 40+ years back, few people, if any, could have foreseen how it looks today. How has the Internet evolved from there to here? What have been the driving forces for the observed consolidation? From a retrospective view, was there anything that might have been done differently to influence the course the Internet has taken? And most importantly, what should and can be done now to mitigate the trend of centralization? Although there are significant interests in these topics, there has not been much structured discussion on how to answer these important questions.

The IRTF Research Group on Decentralizing the Internet (DINRG) organized a workshop on “Centralization in the Internet” on June 3, 2021, with the objective of starting an organized open discussion on the above questions. Although there seems to be an urgent need for effective countermeasures to the centralization problem, this workshop took a step back: before jumping into solution development to steer the Internet away from centralization, we wanted to discuss how the Internet has evolved and changed, and what have been the driving forces and enablers for those changes. The organizers and part of the community believe that a sound and evidence-based understanding is the key towards devising effective remedy and action plans. In particular, we would like to deepen our understanding of the relationship between the architectural properties and economic developments.

This workshop consisted of two panels, each panel started with an opening presentation, followed by panel discussions, then open-floor discussions. There was also an all-hand discussion at the end. Three hours of the workshop presentations and discussions showed that this Internet centralization problem space is highly complex and filled with intrinsic interplays between technical and economic factors.

This report aims to summarize the workshop outcome with a broad-brush picture of the problem space. We hope that this big picture view could help the research group, as well as the broader IETF community, to reach a clearer and shared high-level understanding of the problem, and from there to identify what actions are needed, which of them require technical solutions, and which of them are regulatory issues which require technical community to provide inputs to regulatory sectors to develop effective regulation policies.

You can find the report in the ACM Digital Library. We also have a pre-print version.
