Is It Really Worth Peering at IXPs? A Comparative Study
Is It Really Worth Peering at IXPs? A Comparative Study
roberto di lallo — 03 Aug 2015

We investigated the role IXPs play in the Italian Internet ecosystem. Do peerings at IXPs have a positive effect on key performance indicators such as latency, hop count, packet loss and jitter? Do they reduce the number of out-of-country ISPs traversed by traffic between users located in Italy and critical Internet services like banks and public administrations?… Read more

Analysing the K-root Anycast Infrastructure
Analysing the K-root Anycast Infrastructure
JH Kuipers — 27 Jul 2015

Anycast is used by most of the DNS root-servers and other services like Cloudflare. It provides localisation and scaling benefits to clients using the anycasted service. An anycast service uses one IP for several instances of the same service. The routing system is then responsible for directing a client to the closest instance of the service. In theory, a client should always reach the closest instance, but it turns out that this is not always the case. At the DACS group of the University of Twente, we analysed the anycast infrastructure of K-root and tried to find how many clients reached the closest instance.… Read more

Enabling Data Compression in RIPE Atlas
Enabling Data Compression in RIPE Atlas
Daniel Quinn — 17 Jun 2015

We’d like to enable gzip compression on all of RIPE Atlas' measurement API calls — but thanks to the BREACH vulnerability, doing so could mean that some enterprising individual with an obscene amount of time on their hands might be able read the contents of the responses. This means measurement results as well as metadata for measurements — including the small number of measurements not marked as “public”. We believe the drawbacks are negligible, but we’re looking for community support.… Read more

RIPE Atlas DataViz Hackathon Results
RIPE Atlas DataViz Hackathon Results
Vesna Manojlovic — 10 Apr 2015

In March 2015, a diverse group of contributors got together to come up with creative ways to visualise the health of the Internet using RIPE Atlas open measurements data. It was the first RIPE Atlas hackathon. Impressive results were hacked together by programmers, designers and operators during an intensive weekend of work and fun in Amsterdam. In this article we celebrate hackathon achievements, document and promote hackathon results, create a memento for participants and report in detail for the benefit of the rest of the community.… Read more

Measuring Countries and IXPs with RIPE Atlas
Measuring Countries and IXPs with RIPE Atlas
Emile Aben — 23 Mar 2015

We've been working with various Internet Exchange Points (IXPs) over the last few months to see how RIPE Atlas active measurements can provide insight into how they are keeping local traffic local. This could help improve performance and efficiency for IXPs and their members. To explore this, we've created a set of Python scripts to analyse Internet traffic paths between RIPE Atlas probes in a given country and try to identify whether they traverse IXPs.… Read more

Tracebox, a Tool to Detect Middleboxes
Tracebox, a Tool to Detect Middleboxes
Julien Colmonts — 25 Feb 2015

The increasing number of middleboxes (such as firewalls, NATs, proxies, or Deep Packet Inspection) has raised concerns over the impact of such middleboxes on the network and the possibility to innovate. As a result, operators and researchers are studying the distribution and behaviour of middleboxes in large networks. In this article, we will describe a tool called Tracebox that helps in detecting middleboxes. Tracebox was developed at the Université Catholique de Louvain (UCL) and at university of Liège (ULg) in 2013 and funded by Change (INFSO-ICT-257422), mPlane (ICT-318627), and Bestcom IAP. We believe that adding tracebox-like capabilities to RIPE Atlas could give network operators a deeper insight into their systems and help debugging network problems.… Read more
