RIPE Labs

Internet Exchange Points (IXPs) originally aimed to keep local traffic local and reduce dependence on third parties. However, ever-increasing traffic volumes create pressure for denser and more diverse peering that challenges the traditional IXP model. A fundamental shift in peering practices is Remote Peering (RP): networks may establish remote or indirect peering connections at IXPs, either over a ‘long cable’ (owned or leased) or over resellers that provide both IXP ports and Layer-2 access. RP has fired up a heated debate within the operators’ community about its effects on Internet economics, resilience and performance. Currently, we lack the tools to identify remote members and the implications of RP. To bridge this gap, we developed and tested a methodology to accurately identify RP, aiming to enable a more transparent peering ecosystem.… Read more

At RIPE 77, I talked about what’s been going on with DNS over the past five years from the perspective of end devices. Now in article form, here's what I had to say about the status of the IETF standards for DNS over TLS (DoT) and DNS over HTTPS (DoH) as well as the deployment status of clients and servers for those technologies.… Read more

With an increasing number of route collectors and the resulting increase in available routing data, how do we analyse such a large amount of data in a reasonable time? BGP Scanner was developed to meet the limitations of existing large-scale BGP data analysis tools.… Read more

Computers have always had clocks. Well maybe not clocks as you might think, but digital computers have always had oscillators, and if you hook the oscillator to a simple counter then you have a clock.… Read more

Uninterrupted availability of the Internet has become increasingly critical these days, not just for end users but also for service providers who need to meet Service Level Agreements (SLAs). Yet, outages affecting end-user connectivity are widespread, whether they be unintentional fibre cuts, natural disasters, cyber attacks, or intended Internet shutdowns by governments for political reasons.… Read more

Welcome to the anticipated 2018 Quantum Internet Hackathon report. Here we share the results of last months’ successful hackathon held at the Volkshotel in Amsterdam. … Read more

On-path load balancing can send traffic across many potential paths, which typical traceroute usage will not fully capture. We are working on algorithms for a more complete traceroute across load-balanced paths, and we are interested in deployment on RIPE Atlas. We'd like your feedback.… Read more

Thanks to the RIPE NCC Community Project Fund we were able to revive the OpenBGPD daemon and bring more diversity to the Route Server landscape.… Read more

In the first part of this two-part series, I shared a recent IPv6 deployment case study I worked on for a government network in the LACNIC region, concentrating on the hereditary peculiarities in the network that we had to overcome, many of which are common among government and organisational networks worldwide. This second post is a quick guide to the necessary steps such networks will face during an IPv6 deployment project.… Read more

In this article I will look at corporate networks, which include cases for governments, enterprises and other organisations.… Read more
