Internet exchange points (IXPs) are among the most popular ways for Internet service providers (ISPs) and content distribution networks (CDNs) to exchange traffic. This article gives an analysis of the distribution of vendors chosen by IXP members to connect to IXPs.
As cryptographic analysis and related technologies advance, the signing algorithms at the heart of DNSSEC have to keep up. Moritz Müller and colleagues take a look at barriers on the road to more secure algorithms and discuss ways to make the journey faster.
There have been growing concerns over the last few years about the excessive concentration of control over the Internet's markets and infrastructure — what is commonly referred to as Internet centralisation. In this article, Giovane Moura talks about how he and his colleagues have been measuring ce…
Source Address Validation (SAV) is the best current practice (BCP 38/RFC 2827) aimed at filtering packets based on source IP addresses at the network edge. In this article, we show how to identify networks that do not deploy SAV for incoming traffic.
Oliver Gasser and his colleagues have been investigating the impact of COVID-19 on Internet traffic as seen from a variety of vantage points. Here's an overview of their findings.
A recent extension that aims to add support for transport options to the User Datagram Protocol (UDP) is already showing promise. Unfortunately, its deployment may be undermined by the way existing network devices process UDP length and checksum. In this post we at the Electronics Research Group,…
I’ve created a traffic analyser to help network engineers detect issues related to quality of experience.
