RIPE Atlas Software Probes Survey
by Alun Davies 17 Jun '19

17 Jun '19

Dear colleagues, We are working on making the RIPE Atlas measurement software available as an installable package so you can run RIPE Atlas probes entirely in software without the need of a dedicated physical device. We are interested in your feedback regarding this feature, and we are also looking for volunteers willing to partner with us and help package the software for various operating systems and platforms. Please send your feedback and let us know if you can support RIPE Atlas software probes by filling in this short survey: https://www.ripe.net/participate/forms/apply/atlas-probes/ <https://www.ripe.net/participate/forms/apply/atlas-probes/> Kind regards, Alun Davies RIPE NCC

Dear colleagues, How reliable are website popularity rankings like the Alexa top one million that many of us use in our research? Read this interesting study by Samaneh Tajalizadehkhoob and Victor le Pochat in which they analysed four ranking lists and discovered the impact they have on research results and how easily they can be manipulated: https://labs.ripe.net/Members/samaneh_tajalizadehkhoob_1/the-tale-of-websit… Kind regards, Mirjam Kühne RIPE NCC

New on RIPE Labs: Uncovering Remote Peering at IXPs
by Mirjam Kuehne 12 Dec '18

12 Dec '18

Dear colleagues, 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). The authors developed and tested a methodology based on RIPE Atlas to accurately identify RP, aiming to enable a more transparent peering ecosystem.: https://labs.ripe.net/Members/vgiotsas/uncovering-remote-peering-at-interne… Kind regards, Mirjam Kühne RIPE NCC

Dear colleagues, Here are two more interesting RIPE Labs articles for your weekend reading: 1. When the Internet Goes Down: Tracking Edge Outages at Scale Philipp Richter and his colleagues from MIT and the University of Maryland present a new approach to passively detect Internet edge outages: by leveraging access logs of a major Content Distribution Network (CDN) and tracking anomalies in the access patterns of end users. https://labs.ripe.net/Members/philipp_richter/when-the-internet-goes-down-t… 2. Is the Internet Running Late? Geoff Huston is measuring variance in clock times across the Internet and concludes that almost half of the clocks on the Internet are running fast or slow. https://labs.ripe.net/Members/gih/is-the-internet-running-late Enjoy reading and the authors would love to get your feedback in the comments field.

Measuring MANRS readiness
by Andrei Robachevsky 05 Oct '18

05 Oct '18

Dear colleagues, At RIPE 76 I shared some ideas about how to produce longitudinal measurements related to routing (in)security (https://ripe76.ripe.net/archives/video/147/) The request from the WG was to share a more detailed description of the framework as it shapes up. I attach the description of the framework and the metrics that we (with NLNetLabs as a partner) started to calculate and store. It also contains references to the data sources. The latter are to be extended, we are already working with a few data providers, and if you have ideas about other potential ones - appreciate your suggestions. Below is the summary of the framework: Measurements To measure MANRS readiness for a particular network a set of metrics has been proposed, one for each action. For example, to measure to what degree Filtering (Action 1) is implemented we will measure the number of routing incidents where the network was implicated either as a culprit or an accomplice and their duration. That will produce a number – an indication of the degree of compliance, or a MANRS readiness index (MR-index) for Action 1 for a specified period of time. The measurements are passive, which means that they do not require cooperation for a measured network. That allows us to measure the MR-indices not only for the members of the MANRS initiative, but for all networks in the Internet (at the moment more than 60,000). Metrics Action: Filtering M1 route leak by the AS M2 route misorigination by the AS M1C route leak by a direct customer M2C route hijack by a direct customer M3 bogon prefixes by the AS M4 Bogon ASNs by the AS Action: Anti-spoofing M5 IP Spoofing by the AS M5C IP Spoofing by a direct customer Action: Coordination M8 contact registration (RIR, IRR, PeeringDB) Action: Facilitate global Validation M7IRR Not registered routes M7RPKI Not registered ROAs M7RPKIN Incorrect ROAs Appreciate your feedback and suggestions.

2nd Workshop on Internet Measurements Research in Africa
by Amreesh Phokeer 05 Sep '18

05 Sep '18

{apologies for cross-posting} {please circulate} *2nd IMRA WORKSHOPInternet Measurements Research in Africaco-located to AFRICOMM 2018, 29-30 Nov, Dakar, Senegal* *Call for Papers/Presentations* Internet measurements provide useful insights into the accessibility of the Internet (e.g. coverage of WiFi and cellular networks), performance (e.g. Internet throughput and latency) and Internet usage. Internet development campaigners, national regulators, and policy makers in the developing regions are recognising the crucial role that Internet measurement data can play in facilitating evidence-based policy-making and regulation. Given that the Internet ecosystem comprises a diversity of stakeholders and service providers it is difficult for any other single entity to access all of Internet topology data without the cooperation of the Internet community. For this reason, appropriate acquisition of Internet data requires a variety of cooperative research methods, including wide distribution of Internet probes for technical measurements, located in diverse locations and networks, as well as region-specific techniques and demand-side surveys on Internet access and use. The aim of the workshop is to facilitate discussions around mechanisms and challenges of measuring Africa’s Internet; to evaluate the breadth of Internet measurements research and to formulate strategic directions for such research in Africa; and to initiate and accelerate collaboration among Africa’s Internet measurements researchers. The workshop is calling for high-quality papers that are focused on Internet measurements research in Africa. Papers are invited on topics related to tools, methods and analysis of: End-to-end Internet performance metrics Internet topology characteristics, including peering and routing Application-level performance, including DNS, Web, CDNs, Cloud Computing Physical layer performance measurements, including for TVWS, WiFi, and 3G/4G Mobile and Cellular technologies Detection of middleboxes, censorship, and content filtering Data analytics for network monitoring, traffic analysis and network Network topology and performance visualization Internet access, use, and Quality of Experience (QoE) surveys *Committee* *General Workshop Chair*Amreesh Phokeer <amreesh(a)afrinic.net> – AFRINIC *Technical Programme Committee*Ahmed Elmokashfi <ahmed(a)simula.no> (TPC Co-chair) – Simula Research Laboratory Josiah Chavula <jchavula(a)cs.uct.ac.za> (TPC Co-chair) – University of Cape Town Amreesh Phokeer – AFRINIC Gareth Tyson – Queen Mary University of London Alemnew Asrese – Aalto University Ermias Walelgne – Aalto University Assane Gueye – UADB-Senegal Roderick Fanou – CAIDA/UC San Diego *Publication* Accepted and registered papers will be included in the AFRICOMM conference proceedings. *Submission Instructions* See the instructions for paper submission here: <http://africommconference.org/initial-submission/> Workshop papers will be selected through a peer-review process. N.B Previous and already published peer-reviewed work on Internet measurements may also be accepted for presentation only. Presentations should be emailed to the workshop TPC co-chairs. *Important Dates*Submission deadline: 28th September 2018 Notification deadline: 15th October 2018 Camera-ready deadline: 30th October 2018 -- Amreesh Phokeer
