What are the dimensions of the internet?

JLiebenauOn Monday 10 February, Jonathan Liebenau presented a synopsis of one of the research themes of our team during the February’s London Enterprise Technology MeetUp held monthly at the LSE. Read here Jonathan’s remarks, key questions and possible ways forward of a core theme of our research:  understanding the dimensions of the internet and their implications for business, regulation and the digital economy more broadly.  

I have long been anxious to answer a set of core questions about the digital economy and especially how business is conducted in the internet industry.  Before I could do this I felt it was important to know about the dimensions of the internet.  I wanted at least to know:

  • What are the boundaries of the internet, and how can we distinguish private networks from the open internet?
  • How much traffic passes through the networks, and what are the trends, disaggregated by type of traffic and type of business?
  • What is the speed of traffic, both in the experience of retail customers and as regards the internal, core network?
  • How many people are employed in the sector, where, and for what tasks?

I thought it would be straightforward enough to find out these dimensions, even if more imaginative research would be needed to learn about those features, such as pricing, costs and value added, that we know well about most industrial sectors.

Once my team and I had answers for these basic questions, we could go further with address the burning issues that enliven business debates:

  • What kinds of business models are likely to succeed in the digital economy?
  • What are the labour market effects of changes in digital technologies?
  • Who makes money on what, and how are costs most effectively cross-subsidized?
  • How is value added in the production of digital goods and services, where, and what does this mean for taxation, GDP calculations and other measures central to public policy making?

However, we didn’t get very far.

Cisco measures what goes through their switches, plus a bit more, but they miss out on much and double-count other things.  Besides, their way of disaggregating is not always what business and economic analysts need. Sandvine, AskSam, MIT and U. California, San Diego among others measure download speeds and help us understand retail pricing, congestion and truth-in advertising issues, but that doesn’t tell us much about traffic moving around the system. So, we looked for better models of the internet so as to understand these dimensions.  Such models are being constructed, slowly.  They force us to reconsider old, engineering truths about the way the “layered internet” was supposed to work.  They point us in the direction of assessing big trends that are changing the assumptions about how business can be done with the internet, and about its governance.

Some of these trends are especially indicative and show much about the importance of this kind of research.

  • Large amounts of traffic—the majority of what is delivered to devices, is video, and a huge and rising proportion is mobile.
  • Data centres are integral to the way the internet works not only because of the prevalence of virtualization and cloud services, but also because they provide the means to structure traffic worldwide.  This puts considerable power in the hands of a few big players, including banks, but also Google, Facebook, Amazon and the telecoms, but also Akamai, Level 3 and others in the CDN space.
  • The structure changes as internet exchanges and private contracts for peering and transit re-draw routing worldwide.
  • Differential treatment of traffic both as a consequence of proprietary practices and by “favouritism” –what we thought of as anathema under “net neutrality”.

I am sure that understanding these trends helps us to see deeper into business practices.  It helps us to predict a little better.  It helps us to establish effective governance.  It leads us to a better model that will make it much easier to explore the problems that I had wanted to address at the outset.
