New on RIPE Labs: Pinpointing Delay and Forwarding Anomalies using RIPE Atlas Built-in Measurements
by Mirjam Kuehne 18 May '16

18 May '16

Dear colleagues, Detecting network disruptions is a recurring problem. Clearly locating performance degradation is an important step in debugging and subsequently fixing connectivity issues. In this new RIPE Labs article the authors propose a set of complementary methods to detect network disruptions from traceroute measurements created by RIPE Atlas Built-In Measurements: https://labs.ripe.net/Members/romain_fontugne/pinpointing-delay-and-forward… Kind regards, Mirjam Kuehne RIPE NCC

[dagstuhl seminar]: global measurements: practice and experience
by Bajpai, Vaibhav 12 May '16

12 May '16

Dear RIPE Atlas / MAT WG -- sorry for cross-posting. A SIGCOMM CCR article summarising the Dagstuhl seminar on ‘Global Measurements: Practice and Experience’ just came online [a]. Thought to share it with you: [a] http://www.sigcomm.org/sites/default/files/ccr/papers/2016/April/0000000-00… Background: ===================== We recently helped organise a Dagstuhl seminar on Global Measurements: Practice and Experience [b] from January 04 – 07, 2016. This was a followup of the seminar on Global Measurement Framework [c] which focused on the development of global Internet measurement platforms and associated metrics. [b] http://www.dagstuhl.de/16012 [c] http://www.dagstuhl.de/13472 The second seminar aimed at discussing the practical experience gained with building global measurement platforms. It brought together people who are actively involved in the design and maintenance of global measurement systems, who do research on the data delivered by global measurement systems, and who use data derived from global measurement systems in order to manage networks or services or as input for regulatory decisions. ===================== Best, Vaibhav =================================== Vaibhav Bajpai www.vaibhavbajpai.com Room 91, Research I School of Engineering and Sciences Jacobs University Bremen, Germany ===================================

New on RIPE Labs: How Elasticsearch and Kibana Help us Analyse RIPE Atlas Data Logs
by Mirjam Kuehne 29 Apr '16

29 Apr '16

Dear colleagues, RIPE Atlas backend applications run on more than 40 servers. Each day these machines can produce thousands of application logs of any kind of severity level. In order to be able to track down serious errors, warnings or even unusual behaviour, we decided some time ago to try Elasticsearch as a logging sink. In this article we will look at the design of such a system and describe how we can easily make sense from an ocean of logs: https://labs.ripe.net/Members/andreas_strikos/how-elasticsearch-and-kibana-… Kind regards, Mirjam Kuehne RIPE NCC

New on RIPE Labs: How Pingable are the Pingables?
by Mirjam Kuehne 05 Apr '16

05 Apr '16

Dear colleagues, We look at how the "pingable:" and "ping-hdl:" attributes have been adopted in the last five years and how reachable the pingable addresses registered in the RIPE Database are when pinged from RIPE Atlas. Spoiler alert: It could be better. Please find the details on RIPE Labs: https://labs.ripe.net/Members/wilhelm/how-pingable-are-the-pingables?pk_cam… Kind regards, Mirjam Kuehne RIPE NCC

Last call for presentations and Draft programme for RIPE 72
by Benno Overeinder 02 Apr '16

02 Apr '16

Colleagues, A list of currently accepted RIPE 72 presentations is now published at: https://ripe72.ripe.net/programme/meeting-plan/draft-programme/ There are still few slots remaining for a final RIPE 72 programme and RIPE Programme Committee will accept new proposals until 15 April 2016. This is our last call for you to submit your proposals. You can find the CFP for RIPE 72 below, or at https://ripe72.ripe.net/submit-topic/cfp/, for your proposals for plenary session presentations, tutorials, workshops, BoFs (Birds of a Feather sessions) and lightning talks. Please also note that speakers do not receive any extra reduction or funding towards the meeting fee at the RIPE Meetings. Kind regards, Benno Overeinder RIPE PC Chair https://www.ripe.net/participate/meetings/ripe-meetings/pc -------------------->>><<<-------------------- Call for Presentations A RIPE Meeting is an open event where Internet Service Providers, network operators and other interested parties get together. Although the meeting is mostly technical, it is also a chance for people to meet and network with others in their field. RIPE 72 will take place from 23-27 May 2016 in Copenhagen, Denmark. The RIPE Programme Committee (PC) is now seeking content proposals from the RIPE community for the plenary sessions, BoFs (Birds of a Feather sessions), panels, workshops, tutorials and lightning talks at RIPE 72. See the full descriptions of the different presentation formats, https://ripe72.ripe.net/submit-topic/presentation-formats/. Proposals for plenary sessions, BoFs, panels, workshops and tutorials must be submitted for full consideration no later than 15 April 2016. Proposals submitted after this date will be considered depending on the remaining available space in the programme. The PC is looking for presentations covering topics of network engineering and operations, including but not limited to: - IPv6 deployment - Managing IPv4 scarcity in operations - Commercial transactions of IPv4 addresses - Data centre technologies - Network and DNS operations - Internet governance and regulatory practices - Network and routing security - Content delivery - Internet peering and mobile data exchange Submissions RIPE Meeting attendees are quite sensitive to keeping presentations non-commercial, and product marketing talks are strongly discouraged. Repeated audience feedback shows that the most successful talks focus on operational experience, research results, or case studies. For example, presenters wishing to describe a commercial solution should focus on the underlying technology and not attempt a product demonstration. Presenters should indicate how much time they will require. In general, the time allocated for the different presentation formats is as follows: - Plenary presentations: 20-25 minutes presentation with 5-10 minutes discussion - Tutorials: up to two hours (Monday morning) - Workshops: one hour (during evening sessions) to two hours (Monday morning) - BoFs: approximately one hour - Lightning talks: 10 minutes The following general requirements apply: - Proposals must be submitted using the meeting submission system, https://ripe72.ripe.net/submit-topic/submission-form/. - Lightning talks should also be submitted using the meeting submission system (https://ripe72.ripe.net/submit-topic/submission-form/) and can be submitted any time up to and including the meeting week. The allocation of lightning talks will be announced on short notice---in some cases on the same day but often one day prior to the time slot allocated. - Presenters who propose a panel or BoF are encouraged to include speakers from several (perhaps even competing) companies and/or a neutral facilitator. - All presentation proposals will only be considered by the PC if they contain at least draft presentation slides (slides may be updated later on). For panels, proposals must contain a clear description, as well as the names of invited panellists, presenters and moderators. - Due to potential technical issues, presenters/panellists should be physically present at the RIPE Meeting. If you have any questions or requests concerning content submissions, please email pc [at] ripe [dot] net. -- Benno J. Overeinder NLnet Labs http://www.nlnetlabs.nl/
