OECD Digital Economy Outlook 2017
The biennial OECD Digital Economy Outlook examines and documents evolutions and emerging opportunities and challenges in the digital economy. It highlights how OECD countries and partner economies are taking advantage of information and communication technologies (ICTs) and the Internet to meet their public policy objectives. Through comparative evidence, it informs policy makers of regulatory practices and policy options to help maximise the potential of the digital economy as a driver for innovation and inclusive growth.
The Record Route Option is an Option!
The IPv4 Record Route (RR) Option instructs routers to record their IP addresses in a packet. RR is subject to a nine hop limit and, traditionally, inconsistent support from routers. Recent changes in interdomain connectivity—the so-called “flattening Internet”—and new best practices for how routers should handle RR packets suggest that now is a good time to reassess the potential of the RR Option.
Strategic choice and broadband divergence in the transition to next generation networks: Evidence from Canada and the U.S.
This article investigates how infrastructure competition among broadband network infrastructure operators in Canada and the U.S. has influenced their incentives to increase fixed broadband connection speeds and invest in next generation fiber-to-the-premises (FTTP) technologies. The evolution of measured broadband speeds since the late 2000s documents growing differences in the incentives of dominant broadband operators to respond to demand for higher speed connectivity by increasing connectivity speeds they deliver to their customers. Dominant network operators in Canada have shown relatively stronger incentives than their counterparts in the U.S. to invest in and increase the capacity of legacy platforms. In the U.S. FTTP deployment incentives have been somewhat stronger, but network operators have been more reluctant to upgrade legacy technologies to deliver higher speeds. Diversity of strategic choices by large operators helps explain increasing regional and local broadband infrastructure gaps within the two countries. A high dividend payout financial strategy and increasing vertical integration appear to enhance the potential for overinvestment and inefficient duplication in legacy platforms by competing infrastructure providers.
Regulatory Federalism and Broadband Divergence: Implications of Invoking Europe in the Making of Canadian Telecom Policy
Invocations of Europe are increasingly evident in Canadian debates about wholesale broadband access, consumer protection, network neutrality and basic service policies. While some stakeholders in Canadian debates point to national and local approaches in Europe that appear to have been relatively successful in fostering broadband infrastructure development, others suggest that Europe is lagging behind and Canada should avoid Europe’s purported policy errors.
Towards estimating the untapped potential: a global malicious DDoS mean capacity estimate
What is the malicious reflected distributed denial of service (rDDoS) mean potential of the internet? The authors have been using data from the openNTP project which measures the number of reflectors on the internet since 2014 until now, and completed a graph that roughly estimates a lower boundary for global rDDoS mean potential across four internet protocols (IPs); SSDP, NTP, SNMP and open recursive DNS.
Measuring Broadband in Schools
The challenges that school administrators face when budgeting for and deploying technology vary widely, as do their approaches to supporting its use within their schools. Measuring and assessing network health is a critical challenge facing public schools as they plan for both today’s and tomorrow’s broadband needs. New America’s Open Technology Institute (OTI) and Education Policy program partnered with the IT staff at Alexandria City Public Schools (ACPS) in Virginia to conduct a pilot study as a first step toward addressing this challenge. The study, Measuring Broadband in Schools, looked at the complexities of understanding network capacity in education institutions, and sought to better understand the challenges of measuring network capacity at the point of use in schools.
Measuring Latency Variation in the Internet
The authors analyse two complementary datasets to quantify the latency variation experienced by internet end-users: (i) a large-scale active measurement dataset (from the Measurement Lab Network Diagnostic Tool) which shed light on long-term trends and regional differences; and (ii) passive measurement data from an access aggregation link which is used to analyse the edge links closest to the user. The analysis shows that variation in latency is both common and of significant magnitude, with two thirds of samples exceeding 100 ms of variation. The variation is seen within single connections as well as between connections to the same client. The distribution of experienced latency variation is heavy-tailed, with the most affected clients seeing an order of magnitude larger variation than the least affected. In addition, there are large differences between regions, both within and between continents. Despite consistent improvements in throughput, most regions show no reduction in latency variation over time, and in one region it even increases.
Analysis of Impartial Quality Measurements on Indian Broadband Connections
Broadband Internet user base is growing at an exponential pace in India. The market pressures are forcing the Internet service providers (ISPs) to sell their service offerings aggressively, resulting in a growing discrepancy between consumer expectations and service offerings from the ISPs. This discrepancy is often evident in experienced vs offered Internet connection service. This study examines the Quality of Service (QoS) variations for Internet connections of the Indian broadband users.
CUSUM Anomaly Detection
The CUSUM anomaly detection (CAD) method is based on CUSUM statistical process control charts. CAD is used to detect anomalous subsequences of a time series that show a subtle shift in the mean relative to the context of the sequence itself. CAD was applied in order to look for anomalies in MLab’s database of Network Diagnostic Tool (NDT) results.

OECD Digital Economy Outlook 2015
This report assesses how countries can maximise the potential of the digital economy as a driver for innovation and inclusive growth, and discusses the evolutions in the digital economy that policy makers need to consider as well as the emerging challenges they need to address as a part of national digital strategies. Chapters include an overview of the current status and outlook of the digital economy; the main trends in the ICT sector, and developments in communication and regulation policy; and overviews of ICT demand and adoption, plus the effects of the digital economy on growth and development. This volume also includes a chapter on developments related to trust in the digital economy and on the emerging Internet of things.
Public QoS and Net Neutrality Measurements: Current Status and Challenges Toward Exploitable Results
The interest for Quality of Service (QoS) measurements in the Internet has exceeded the boundaries of research laboratories and passed into the public domain. The Internet is treated as a public utility, and users are given the right to access Internet content of their choice at an adequate quality. This coincides with the sustained interest for net neutrality (NN), basic safeguards for which are being taken in countries all over the world. Today, several tools have become available that empower end-users to measure the performance of their Internet connection and detect NN violations. However, the value that end-users obtain with these measurements is still small and the results are not being exploited satisfactorily by regulatory authorities, policy makers, and consumers. In this article, we perform a detailed review of the tools that are currently available for public QoS and NN measurements and explore three challenges that must be met in order to extract more value from the results: (a) Harmonization of measurement methodologies of basic performance parameters (throughput, delay, jitter, and packet loss); (b) the creation of a toolbox for detecting and monitoring NN violations; and (c) the use of a proper sampling plan for producing estimates over population groups.
European capability for situational awareness
This study examines the field of Internet and Human Rights and more specifically, Internet Censorship measurement. The European Commission DG-Connect commissioned this study to assess the potential for a European Capability for Situational Awareness that continuously monitors and analyses the existence of Internet interference in combination with Human Rights Violations and recommend on potential implementation of such an ECSA. A proof-of-concept website was produced along with this report.
Analysis of End-User QoE in Community Networks
Community networks are a potential model for the Future Internet, where the users form and operate the network instead of a central, commercial entity. Socio-economic studies show that community networks are an excellent model to develop networking infrastructure commons (as common-pool resources or public goods) that promote sustainable development, with greater effects in less developed areas. The performance of parts of community networks has been studied extensively, often focusing on routing protocols or applications on top of community networks. This work focuses on the end-to-end quality of Internet access in community networks, as a validation of the technical applicability of this concept in under-served regions.
