Centrality and the Internet

The IRTF is a research-oriented part of the larger IETF structure. It has a number of research groups, one of which, DINRG, is looking at decentralized Internet Infrastructure.

That's a big topic, and one could certainly look at distributed decentralized blockchain frameworks applied to ledgers, used by Bitcoin and similar, or self-organizing systems that perform orchestration without imposed control or distributed hash tables. This research group certainly has done this and more over the past few years. However, much can also be learned from looking at the opposite of decentralized systems and lift our view from individual components to the entire industry. To what extent is the Internet now centralized?

It certainly seems that the Internet is now the realm of a small number of enterprises that dominate this space. This is no longer a diverse, vibrant environment where new entrants compete on equal terms with incumbents, where the pace of innovation and change is relentless, and users benefit from having affordable access to an incredibly rich environment of goods and services that is continually evolving. Instead, today's Internet appears to be re-living the telco nightmare where a small clique of massive incumbent operators imposes overarching control on the entire service domain, repressing any form of competition, repressing innovation, and extracting large profits from their central role. The only difference between today and the world of the 1970s is that in the telco era, these industry giants had a national footprint. In contrast, these days, their dominance is expressed globally.

How did we get here? Why did a network technology such as the Internet, which was designed to pass control away from the central network to the connected devices, succumb to the same level of centrality?

Those questions were the topic of the most recent meeting of the DINRG (held online, of course, in these Covid-cursed times).

What follows here are my thoughts on this topic of centrality. My presentation slides, looking at the larger issues of market dominance using a historical perspective, can be found here.

It's Just Economics

In classical public economics, one of the public sector roles is to detect and presumably rectify situations where the conventional operation of a market has failed. But, of course, a related concern is not just the failure of the efficient operation of a market, but the situation where the market collapses and simply ceases to exist. In an economy primarily led by private sector activity, the health of the economy is highly dependent on the efficient operation of such markets. Inefficient markets or distorted markets act as an impost on the economy, imposing hidden costs on market actors and deterring further private sector capital investment.

In such a light, markets are more than mere enablers of simple transactions between buyers and sellers. Karl Marx was one of the first economists to think about the market economy as a global entity and its fundamental role as an arbiter of resource allocation in society. When we take this view and start looking for potential failure points, one of the signs is that of "choke points" where real investment levels fall. Such failures are often masked by a patently obvious masquerade of non-truths taking the place of data and facts. Any study of an economy involves understanding the nature of these chokepoints. Telecommunication services are not an isolated case but can be seen as just another instance of a choke point in the larger economy. Failure to keep common communications services functioning efficiently and effectively can have implications across many other areas of economic activity.

What defines an "efficient" market? From the perspective of Adam Smith, the precondition is unconstrained consumers (who can purchase a good from any provider), replaceable providers of the good or service being traded, open pricing information, and open access to the marketplace. Consumers will be motivated to buy the good from the producer that brings the product to market at the lowest price, and producers will be motivated to seek the most efficient form of production of the good in order to sustain a competitive market price. However, that is by no means the final word here, and the Nobel Prize-winning efforts of Eugene Fama in 1970 are also relevant to this question, where an "efficient" market is one where market prices reflect all available relevant information at the time.

A continuing source of pressure on markets is that of innovation. New products and services can stimulate greater consumer spending or realize greater efficiencies in the production of the service. Either outcome can lead to the opportunity of greater revenues for the enterprise. But, of course, the assumption is that innovation is unconstrained, and market incumbents cannot define the scope or accessibility of further innovations in the market.

Innovation within the Internet occurs in many ways, from changes in the components of a device through to changes in the network platform itself and deployment of applications. We've seen all of these occur in rapid succession in the brief history of the Internet, from the switch to mobility, the deployment of broadband access infrastructure, the emerging picture of so-called "smart cities," and of course the digitization of production and distribution networks in the new wave of retailing enterprises. We've seen the evolution of platforms from megalithic "mainframes" to deeply embedded processors and the evolution of the locus of control and orchestration from the network through to device platforms through to the individual applications themselves.

Much of this innovation is an open process that operates without much in the way of deliberate direction or deterministic predictability. Therefore, governance of the overall process of innovation and evolution cannot concentrate on the innovative mechanism per se but necessarily needs to foster the process by supporting the underlying institutional processes of research and prototyping. Through much of the twentieth century, the conventional wisdom was that public funding through direct support of basic research was the only way to overcome prohibitively high transaction and adaptation costs in exploring innovative opportunities. However, behind this lies an assumption that the public sector has a higher risk appetite and a larger capital volume than individual private sector actors. However, the transformation of wealth and capital markets in the latter part of the twentieth century has changed all this. For example, with a current market capitalization of 2 trillion USD Apple has a higher "worth" than all bar 8 of the world's national economies, as measured by national GDP. This has an impact on who has the capital and appetite to engage in high-risk ventures in innovation. However, the interests of the private and public sectors are fundamentally different, and while the public sector has a strong motivation for innovation as an open activity whose results are accessible to all, the private sector tends to view its investments in innovation in a more proprietorial way. When innovation is managed in such a way through the private sector, it no longer has the same ability to bring competitive pressure to bear on markets. It often tends to work oppositely by further entrenching the position of market incumbents through their exclusive access to innovation in production.

Size and Centrality

Business transformation is often challenging. What we have today within the Internet with the rise of content and cloud providers into dominant positions in this industry is a more complex transformational environment that is mainly opaque to external observers. What matters for consumers is their service experience, which depends increasingly on what happens inside these content distribution clouds. As these content data network operators terminate their private distribution networks closer to the customer edge, the role of the traditional carriage service providers, which used to provide the connection between services and customers, is shrinking. But as their role shrinks, we also need to bear in mind that these carriage networks were the historic focal point of monitoring, measurement and regulation. As their role shrinks, so does our visibility into this digital service environment.

It is a significant challenge to understand this content economy. What services are being used? What connections are being facilitated? What profile of content traffic are they generating? Just how valuable is this activity? Suppose we can't directly observe these activities. In that case, the question of the value of these activities and the extent to which these markets are openly competitive become more challenging to answer. In the absence of effective competition, markets tend to consolidate and succumb to monopolization and centralization. "Big" often becomes the defining characteristic of such markets.

This brings into the forefront a venerable economic topic: Is big necessarily bad?

There is little doubt that today's digital environment is dominated by a small number of very big enterprises. As determined by market capitalization, the largest public companies include the US enterprises Apple, Alphabet, Amazon, Facebook, Microsoft and Facebook, and the Chinese enterprises Alibaba and Tencent. Admittedly, other metrics of size include metrics of revenues, profits, customers, and the scope and impact of a corporate enterprise, but the considerable market capitalization of these seven companies place them in the global top ten, which makes them outstandingly big. But are they necessarily bad? Does the combination of their unprecedented size and clear market dominance lead to business practices that are exploitative of their workforce? Or practices that are exploitative of their consumers? Or behaviors that are corrupt or collusive? Perhaps their size leads to a point to economic fragility where, if these enterprises were to fail, other parts of our economy would fail as well, and we would be confronted with yet another major economic crisis with its attendant societal impact. The global financial crisis of 2008 has explored the concept of "too big to fail" in the financial world. Do we have a similar situation with some or all of these digital service enterprises?

A Brief Historical Perspective

At the start of the twentieth century, a member of the US Supreme Court, Louis Brandeis, argued that big business was too big to be managed effectively in all cases. He argued that the growth of these very large enterprises that were at the extreme end of the excesses of monopolies and their behaviors harmed competition, harmed customers, and harmed further innovation. He observed that the quality of their products tended to decline, and the prices of their products tended to rise. When large companies can shape their regulatory environment, take advantage of lax regulatory oversight to take on more risk than they can manage, and transfer downside losses onto the taxpayer, we should all be very concerned.

It is hard to disagree with Brandeis if this outcome is an inevitable consequence of simply being big, and given the experiences of the 2008/2009 financial meltdown, we could even conclude that Brandeis' observations apply to the financial sector. But do these systemic abuses of public trust in the financial sector translate to concerns related to the Internet and the broader aspect of the emergence of the so-called digital society?

Brandeis' views did not enjoy universal acclaim. Others at the time, including President Theodore Roosevelt, felt that there were areas where there were legitimate economies of scale and that large enterprises could achieve higher efficiencies and lower prices to consumers in the production of goods and services by virtue of the volume of production. The evolution of the auto manufacturing industry in the early twentieth century and the electricity industry both took exotic and costly products and applied massive scale to the production process. The results were products that affordable by many, if not all, and the impact on society was truly transformational. The US administration of the day moved to implement regulatory oversight over these corporate behemoths but not necessarily act to dismantle their monopoly position.

Regulation?

But if the only oversight mechanism is regulation, have we have allowed the major corporate actors in the digital service sector to become too big to regulate? Any major enterprise that can set its own rules and then behave in a seemingly reckless fashion is potentially damaging to the larger economy and the stability of democracy. One need only mention Facebook and elections in the same sentence to illustrate this risk of apparently reckless behavior.

To quote Brandeis again: "We believe that no methods of regulation ever have been or can be devised to remove the menace inherent in private monopoly and overwhelming commercial power."

But suppose we choose to reject Brandeis' view and believe that regulation can provide the necessary protection of public interest. In that case, it is reasonable to advance the proposition that we need to understand the activity we are attempting to regulate. Such an understanding might be elusive. In the digital networking world, we see more and more data traffic go 'dark.' Content service operators use their own transmission systems or slice out entire wavelengths from the physical cable plant. This withdrawal of traffic from the shared public communications platform is now not only commonplace, but the limited visibility we have into this activity suggests that even today, the private network traffic vastly overwhelms the volume of traffic on the public Internet, and the growth trends in the private data realm also are far greater than growth rates in the public Internet.

How can we understand what might constitute various forms of market abuse, such as dumping, deliberate efforts to distort a market, or discriminatory service provision when we have no real visibility into these private networks? Yet, these private networks are essential. They are driving infrastructure investment, driving innovation, and indirectly driving the residual public network service. Are we willing and able to make an adequate case to expose, through various mandatory public filings, reports and measurements, the forms of use of these privately owned and operated facilities and services? Do we have the regulatory power to do so, considering the size of the entities we are dealing with? We've seen in the past the many national regimes have attempted to avoid the test of relative power by handing the problem to another jurisdiction. The anti-trust action against Microsoft was undertaken in Europe, and even then, the result was largely unsatisfactory. Even if we might believe that greater public exposure of the traffic carried by the dark networks might be in the public interest, we might simply not have the capability to compel these network operators to undertake such public reporting in any case.

Consolidation?

The Internet has been constructed using a number of discrete activity areas, and each area appeared to operate within a framework of competitive discipline. Not only could no single actor claim to have a dominant or overwhelming presence across the entire online environment, but even in each activity sector, there was no clear monopoly position by any single actor.

Carriage providers did not provide platforms, and platform providers did not provide applications or content. The process of connecting a user to a service involved a number of discrete activities and different providers. The domain name being used can be from a name registrar, the DNS lookup was an interaction between DNS resolver application and a DNS server host, the IP address of the service was provided by an address registry, the credentials used for the secured connection came from a domain name certification authority, the connection path provided by a number of carriage providers, and the content was hosted on a content delivery network, used by the content provider. All of this was constructed using standard technologies, mostly, but not exclusively, defined by the IETF.

This diversity of the elements of a service is by no means unique, and the telephone service also showed a similar level of diversity. The essential difference was that in telephony, the orchestration of all of these elements was performed by the telephone service operator. Within the Internet, it appears that there is no overarching orchestration of the delivered composite service. It would be tempting to claim that the user is now in control, but this is perhaps overreaching. Orchestration happens through the operations of markets, and it would appear that the market is undertaking the role of resource allocation. However, the user does have a distinguished role in that it is the users' collective preference for services that drives the entire supply side of this activity.

But this is changing, and not necessarily in a good way. Services offered without cost to the user (I hesitate to use the term "free" as this is a classic two-sided market instance where the user is, in fact, the "goods" being traded between advertisers and platforms) have a major effect on user preferences. However, there is also the issue of consolidation of infrastructure services.

As an example, Alphabet operates not only an online advertising platform but also a search engine, a mail platform, a document store, a cloud service, a public DNS resolver service, a mobile device platform, a browser, mapping services, to name just a few. It appears that in this case, it is one enterprise with engagement in many discrete activities. The issue with consolidation is whether these activities remain discrete activities or whether they are being consolidated into a single service.

We are witnessing a deeper and perhaps more insidious form of consolidation within the Internet than we've seen to date with various corporate mergers and acquisitions. Here it's not the individual actors that are consolidating and exercising larger market power but the components within the environment that are also consolidating. Much of this is well outside of the realms of conventional regulatory oversight, as the results are vertical integration where what we thought of as discrete market sectors is being consolidated and centralized.

The Economics of Advertiser Funding

The question still remains as to how a small set of dominating incumbents retain their overarching position?

I suspect that advertising plays a fundamental role in today's Internet, in the same manner as it has played in the past in other consumer-oriented mass-market communications systems, including the press, television and radio.

Conventionally, the "total value" of a market is based on the sum of the value of the goods or services traded within that market. In this framework, the implication is that any investment in market disruption through the development of innovating responses to meeting the demands expressed within the market is implicitly limited by the net current value of the market. The innovation by any actor is intended to allow the actor to gain greater market share. In contrast, the market's overall value is limited by the current value of the larger economy in which the market operates.

However, the use of advertising as a source of revenue has transformed many markets in the past, such as the press, radio and television. Advertising allows the value of future consumer decisions to be bought to bear on the current market, potentially increasing the value of the current market by a proportion of the expected future value of the market. Market actors who use advertising as a source of revenue are no longer seeing the total value of the market just in terms of the total value of current transactions but instead can factor in some proportion of future transactions. This higher valuation of the market on the part of the advertising platform can then justify increased investment in the market development and innovation based on this higher valuation.

It appears that advertising-based vehicles have to a very extent, an advantage in the market. But why is this market prone to consolidation? Why is this a winner-takes-all form of market dynamics?

It appears that there are very real dynamics of scale in advertising. Advertisers want their message to be seen by the greatest number of potential consumers, and advertising platforms want to provide a service to the greatest number of potential advertisers. The larger the platform, the greater the potential of the platform to meet both of these requirements. The result is intense pressure to consolidate in this market. And that is what we are seeing. And, of course, the Internet is now inexorably entwined in this situation. We wanted the Internet to be "free," and today, it certainly is. I can use a search engine to query a massive compendium of our accumulated knowledge and more without paying a cent! I can access tools and services for free. I can store all my digital data without cost to me. It sure looks like a "free" Internet to me! But is the inevitable cost of all of this one of overarching centrality and dominance by a small collection of global megalithic enterprises that distorts much of the rest of the global economy?

Re-Regulation?

In an earlier time, the Internet was seen as a poster child of deregulation of telecommunications regimes. Entrepreneurial private sector investment revolutionized a bloated and sluggish telco sector, applying the efficiencies of digitization of information and services into a broad range of service sectors. This has transformed retail banking, the postal sector, entertainment, transport, government and many other areas.

But this intense level of disruption in these markets was unsustainable in the longer term, and what we've seen since then has been progressive consolidation. As economies of scale come into play, the larger market actors assume dominant positions and then create conditions of entrenched monopoly. A small number of digital platforms have amassed a greater level of value, and a far greater level of market control than their telco predecessors could ever have contemplated.

And once more, we are left contemplating how to deal with the result. There is no appetite to persist with market-based control mechanisms intended to replace the previous regulatory frameworks. Still, we are also facing a situation where "too big to regulate" is now very much a current risk.

We appear to be seeing a resurgence of expressions of national strategic interest. The borderless, open Internet is now no longer a feature but a threat vector to such expressions of national interest. We see a rise in the redefining of the Internet as a set of threats, in terms of insecurity and cyber-attacks, in terms of workforce dislocation, in terms of expatriation of wealth to these stateless cyber giants, and many similar expressions of unease and impotence from national communities.

It seems to be a disillusioning moment where we've had a brief glimpse of what will happen when we bind our world together in a frictionless, highly capable, universally accessible common digital infrastructure, and we are not exactly sure if we really liked what we saw!

The result appears to be that this Internet that we've built looks like a mixed blessing that can be both incredibly personally empowering and menacingly threatening at the same time!
