Keynote speakers

  • Andrew Odlyzko, Professor in the School of Mathematics, University of Minnesota (Minneapolis)

    • Keynote talk: “Economics, QoS, and charging in the next great telecom revolution”

    Abstract: While the Internet has attracted the bulk of the attention from the public as well as from researchers, the growth of wireless has had a far larger impact on the world, as measured by the number of users, the revenues, or the profits. Technology is leading to a convergence of the two areas, and this will be the next great telecom revolution. The relation between technological progress and consumer demand differs greatly in wireless from what continues to prevail on the wireline Internet, and this is leading to a reconsideration of some of the QoS and charging schemes that failed to find acceptance in the past. A perspective will be presented on what approaches are most likely to succeed, and why.

    • Speaker's bio:

    Andrew Odlyzko is a Professor in the School of Mathematics at the University of Minnesota. He is engaged in a variety of projects, from mathematics to security and Internet traffic monitoring. His main task currently is to write a book that compares the Internet bubble to the British Railway Mania of the 1840s, and explores the implications for future of technology diffusion.
    Between 2001 and 2008, he also was at various times the founding director of the interdisciplinary Digital Technology Center, Interim Director of the Minnesota Supercomputing Institute, Assistant Vice President for Research, and held an ADC Professorship, all at the University of Minnesota. Before moving to Minneapolis in 2001, he devoted 26 years to research and research management at Bell Telephone Laboratories, AT&T Bell Labs, and AT&T Labs, as that organization evolved and changed its name.
    He has written over 150 technical papers in computational complexity, cryptography, number theory, combinatorics, coding theory, analysis, probability theory, and related fields, and has three patents. He has an honorary doctorate from Univ. Marne la Vallée and serves on editorial boards of over 20 technical journals, as well as on several advisory and supervisory bodies.
    He has managed projects in diverse areas, such as security, formal verification methods, parallel and distributed computation, and auction technology. In recent years he has also been working on electronic publishing, electronic commerce, and economics of data networks, and is the author of such widely cited papers as “Tragic loss or good riddance: The impending demise of traditional scholarly journals,” “The bumpy road of electronic commerce,” “Paris Metro Pricing for the Internet,” “Content is not king,” and “The history of communications and its implications for the Internet.” He may be known best for an early debunking of the myth of Internet traffic doubling every three or four months and for demonstrating that connectivity has traditionally mattered much more for society than content.

  • Tommaso Valletti, Professor of Economics at Imperial College Business School (London) and titular Professor of the “Innovation & Regulation in Digital Services” Chair at Telecom ParisTech and Ecole Polytechnique (Paris)

    • Keynote talk: “Unbundling the incumbent: Evidence from UK broadband”

    Abstract: We consider the impact of a regulatory process that forces an incumbent telecoms operator to make its local broadband network available to other companies (“local loop unbundling”, or LLU). Entrants are then able to upgrade their individual lines to offer Internet services direct to the customer. We employ a very detailed dataset covering the whole of the UK. We find that, over time, many entrants use LLU. However, unbundling decreases broadband penetration, compared to those areas where the loops are not unbundled. LLU entry instead has a strong and positive impact on quality of the service. We also assess the impact of competition from an alternative technology (cable) which is not subject to regulation, and find that inter-platform competition has a positive impact both on penetration and quality.
