Call for Papers: RIPE 67, 14-18 October 2013 in Athens, Greece
by Benno Overeinder 23 Jul '13

23 Jul '13

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 67 will take place from 14-18 October 2013 in Athens, Greece. The RIPE Programme Committee (PC) is now seeking content proposals from the RIPE community for the plenary session presentations, BoFs (Birds of a Feather sessions), panels, workshops, tutorials and lightning talks at RIPE 67. 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. The RIPE PC accepts proposals for different presentation formats, including plenary session presentations, tutorials, workshops, BoFs (Birds of a Feather sessions) and lightning talks. See the full descriptions of these formats at https://ripe67.ripe.net/programme/i-want-to-present/presentation-formats/ Presenters who are proposing a panel or BoF are encouraged to include speakers from several (perhaps even competing) companies and/or a neutral facilitator. In addition to presentations selected in advance for the plenary, the RIPE PC also offers several time slots for "lightning talks", which are selected immediately before or during the conference. The following general requirements apply: - Proposals for plenary session presentations, BoFs, panels, workshops and tutorials must be submitted for full consideration no later than 4 August 2013, using the meeting submission system (https://ripe67.ripe.net/submit-topic/) Proposals submitted after this date will be considered on a space-available basis. - Lightning talks should also be submitted using the meeting submission system (https://ripe67.ripe.net/submit-topic/) and can be submitted just days before the RIPE Meeting starts or even during the meeting week. The allocation of lightning talk slots will be announced in short notice - in some cases on the same day but often one day prior to the relevant session. - Presenters should indicate how much time they will require. See more information on time slot allocations per presentation format (https://ripe67.ripe.net/programme/i-want-to-present/presentation-formats/) - Proposals for talks 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 panelists, presenters and moderators. - Due to potential technical issues, it is expected that most, if not all, presenters/panelists will 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/

PORTOLAN: A Mobile Crowdsourcing Measurement System
by Luciano Lenzini 08 Jul '13

08 Jul '13

Dear All, The University of Pisa and IIT, an Institute of the Italian National Research Council, have developed a mobile crowdsourcing-based system, named PORTOLAN which uses smartphones as mobile monitors probing the Internet and reporting results to a central server located in Pisa. The aim of PORTOLAN is to enhance the current topology of the Internet at the Autonomous System level of abstraction - all with the contribution of volunteers. The PORTOLAN component that runs on smartphones is now available as an app for the Android platform. It can be downloaded by users from Google play ( <https://play.google.com/store/apps/details?id=it.unipi.iet.portolan.tracero ute> https://play.google.com/store/apps/details?id=it.unipi.iet.portolan.tracerou te). PORTOLAN works in the background, it is designed not to interfere in any way with users' activities and does not affect the smartphone's overall performance. In order to motivate users to contribute to the PORTOLAN project, we have added several services, which include diagnostic network tools (such as Ping, Paris Traceroute with Multipath Detection Algorithm, Maximum Throughput achievable along a path, etc.) and coverage measurement tools. All the tools are totally under the user's control. Data collected by these tools are stored in our servers, in a completely anonymous way. For details see <http://portolan.iet.unipi.it/> http://portolan.iet.unipi.it/. The success of our experiment depends upon the number of users who join the experiment. But to get people to download the app, we really need to raise as much awareness as possible regarding the PORTOLAN itself. So I would like to ask you if it would be possible for you to forward this message to your colleagues, students and anyone else who you think might be interested. Many thanks in advance for your cooperation. All the best, Luciano TECHNICAL NOTE: In PORTOLAN, each smartphone issues at max 200 traceroutes per day, which means a peak traffic rate never higher than 1 KB/s and an average traffic rate never higher than 2 MB/day. The impact of these activities on the battery consumption is negligible. Signal coverage measurements are completely costless in terms of energy or bandwidth, as the PORTOLAN app passively collects signal strength samples using GPS positions generated by other apps. You have to activate the GPS yourself if you want a coverage map along your route. Given that your route could be up to 50 km or more, then you will obviously use up quite a bit of your battery power. So if you are travelling, then connect your smartphone to a powersource in your car or in the train. In any case, if the battery level goes under 40%, PORTOLAN is automatically suspended. -------------------------------------------------------------- Prof. Luciano Lenzini Department of Information Engineering University of Pisa, Italy e-mail: l.lenzini(a)iet.unipi.it http://www.iet.unipi.it/~lenzini

[Fwd: Community suggestion for ATLAS spoof test]
by Vesna Manojlovic 21 May '13

21 May '13

Dear colleagues, please take a look at the suggestion from Alexander Isavnin. Since he is here in Dublin, we can talk about it during MAT-WG or, if there is not enough time, at the RIPE Atlas community BoF. However, the opinion of the rest of the community counts too, so I ask you to comment on the mailing list, if you are interested. Regards, Vesna -------- Original Message -------- Subject: Community suggestion for ATLAS spoof test Date: Wed, 15 May 2013 21:16:30 +0200 From: Alexander Isavnin <isavnin(a)netline.ru> To: Vesna Manojlovic <BECHA(a)ripe.net> Dear Vesna! Could you forward this suggestion to mat-wg mailing list (and other appropriate lists). Due to high requirements to mitigate spoofing there is need to detect one. RIPE community have great distributed networking tool - ATLAS. As first step i suggest to select address from RIPE NCC network and allow all probes (if probe is not behind NAT) to send spoofed packet with this address as source. As first and a half step - allow to send packets with source addresses of anchors (if anchor's host agrees) As second step - allow probe host to permit use his address as spoofed source. Best regards, Alexander Isavnin

Re: [mat-wg] [Fwd: Community suggestion for ATLAS spoof test]
by k claffy 20 May '13

From: Antoin Verschuren <antoin.verschuren(a)sidn.nl> If all we want to know is an oversight of the state of spoofing now, and in a year's time, can't we just ask the Atlas users (AKA the mailinglist) that want to know to do a 1 time spoofing test on http://spoofer.csail.mit.edu/summary.php from their atlas probe network? IMHO that is less work than to ask Atlas users for permission. Antoin, Thanks for suggesting that, we agree that Atlas nodes are a terrific way to increase the scope of visibility of spoofing. I should note that we have spent the last few months updating the 7-year old spoofer code and web site (btw, it's now at http://spoofer.cmand.org/ , jointly managed by Rob Beverly at nps.edu and CAIDA) including adding tests for IPv6 spoofing ability, making graphs on the summary page clearer, classifying spoofing-capable networks into types, and allowing probing to multiple (CAIDA Ark) destintations (which also increases visibility into spoofing, but not nearly as much as 1000+ Atlas nodes would..) we plan to deploy and announce an updated version by 1 June. so if you're going to encourage Atlas nodes to try our spoofer test, it would be ideal to have them do it shortly after 1 June. we will send an announcement to this list when we release the new version. after june we will still be working on better techniques to filter tests for representativeness, and other methodology improvements. please do send us requests for other changes/additions you would like to see. ( http://spoofer.cmand.org/contact.php ) thanks, k (and Rob Beverly and Ryan Koga, current team)
