Re: [ipv6-wg] IPv6 only network (not just at RIPE xx meeting)
by Geert Jan de Groot 06 Jun '14

06 Jun '14

Hi all, Not attending RIPE-meetings myself anymore these days, I'm not sure whether (just) a IPv6-only network at a meeting is going to cut it. This has been done for a number of years worth of meetings and while the results are interesting, I'm not sure that a RIPE-meeting is a requirement to run these experiments. It makes perfect sense to run a V6-only network at home/office and get the experience all year, not just during a meeting. So, as a typical home user these days, I run a V6-network, some pieces of it being V6-only, other places being V6-preferred, and the experiences are, eumm, mixed. I frequently find sites (at various ISP's) that are either partially or fully broken for V6. In many instances, happy eyeballs rescues things, that is, things seem just slow but not entirely broken unless one analyzes. Reporting a V6-broken website to it's hoster is, in many cases, a waiste of time. Helpdesks don't understand the problem. If I'm lucky I get a response. Problems are seldom resolved. I think I see this five times per month or so. Perhaps I should browse less. Thing is, we seem to be working on making the Internet V6-capable, but currently V6 performance and stability is a serious issue, especially when it comes to reporting problems. Happy eyeballs mean that the V6-network can, in many cases, just be switched off without anybody noticing. We all know of stories of support/helpdesk folk telling people just to switch off V6. That's all nice if it'd just be an academic exercise but not if it is supposed to be the main bread and butter in the years to come. So, my question to the WG: does the WG think this is a problem, and can we think of a way to get clueful v6 complaints to clueful handlers, instead of being ignored / misaddressed / ...? Geert Jan

Resignation as co-chair of ipv6
by David Kessens 22 May '14

22 May '14

Hi, My personal circumstances have changed in such a way that I most recently did not spent as much time and effort for the ipv6 working group as it deserves. At the same time, I have served the working group for over 15 years and it would certainly not be unreasonable to think that it is good for the working group to change direction. Considering the above, I have decided to resign as co-chair of the ipv6 working group. I hope that this change will give a chance to a new generation of RIPE participants to play a role as a chairperson of a working group and as a participant in the RIPE working group chair collective. Thanks, David Kessens ---

Follow-Up on Niall's talk: Ramond (RA Monitoring Daemon)
by Benedikt Stockebrand 21 May '14

21 May '14

Hi folks, after his presentation learned from Niall that he didn't actually know about the ramond, so here's some quick info for all who have a similar situation like him: Ramond is a little tool that listens for RAs and then matches the source MAC address or whatever with a list of authorized routers. It can clean up after rogue router RAs by sending a follow-up RA with router lifetime of 0 and deprecating all the advertised prefixes, and it can also run some external programs/scripts to do additional clean up (like an automated retaliation strike). It's open source and should run on all standard Unixes (so far I've only tested it on Linux myself), and of course it can be combined with 802.1Q. I've also covered it in the second half of my video blog episode at http://www.stepladder-it.com/bivblog/23 with the most relevant parts starting at about 15:00 into the video. If you handle networks with a potential for rogue advertising routers and don't know about the tool, I recommend you take a look at it.

Introducing the IPv6 Analyser
by Alex Band 20 May '14

20 May '14

Dear colleagues, You can now visit the LIR Portal and try out seamless RIPE Database object creation using the IPv6 Analyser: https://www.ripe.net/s/zToA The IPv6 Analyser is a toolset that offers our members a visual insight into all the allocations, aggregations and assignments they have made. This is the first toolset that seamlessly integrates with the RIPE Database, allowing you to create new objects with an easy-to-use wizard that guides you through the process, searching for available space, and pre-filling known information. Our goal is to unify resource management in the LIR Portal by extending these design principles to organisation, routing and Reverse DNS management. Now that the core design is available, we very much look forward to your feedback on how we can make the IPv4 and IPv6 Analyser as useful as possible. Kind regards, Alex Band Product Manager RIPE NCC

This advancement provides the opportunities to bridge the physical components/processes and the cyber space leading to the Cyber Physical Systems (CPS). The notion of CPS is to use computing (sensing, analyzing, predicting, understanding, etc.), communication (interaction, intervene, interface management, etc.) and control (inter-operate, evolve, evidence-based certification, etc.) to make intelligent and autonomous systems. Such systems are playing an increasingly prevalent and important role in this electronic era such as healthcare, manufacturing, civil infrastructure, aerospace, entertainment, transportation and many automated physical systems. Computing and networking are two major components of CPS and Cloud has infinite resources for both. Cloud-integrated CPS will not only enhance CPS itself but also process, analyze! and manage (CPS) big data efficien tly. However, there are many issues and hurdles of Cloud-integrated CPS that need discussions. Our aim is to provide a platform for researchers and practitioners to present their research results in the area of Cloud-integrated Cyber-Physical Systems. The proposed workshop CloudCPS-2014 will serve as a forum for researchers from academia, government and industries to exchange ideas, present new results and provide future visions on these topics. Topics of interest include but not limited to: - Cloud-CPS Architecture - Cloud-CPS Modeling and Simulation - Virtualization of Physical Components in Cloud-CPS - Design and Performance Optimization in Cloud-CPS - Cloud-assisted Situation-aware and decision support - Big-data Processing and Visualization in Cloud-CPS - Mobile Cloud-CPS - Game Theory for Cloud-CPS - Tools and Methods for Cloud-CPS - Sensor-actuator Networks - Security, Privacy, and Trust in Cloud-CPS - Intelligent (Road/Air) Transportation Cloud-CPS - Cloud-CPS in healthcare - Cloud-CPS in energy - Fog computing - Cloud-CPS: Tools, test beds and deployment issues - Opportunistic spectrum access for Cloud-CPS ***************************** SUBMISSION INSTRUCTIONS ***************************** The authors are advised to submit their research paper following the IEEE CS format: two columns, single-spaced, including figures and references, using 10 fonts, and number each page. Instructions for authors how to format the manuscript can be found at: http://www.computer.org/portal/web/cscps/submission/ http://www.computer.org/portal/web/cscps/formatting/ The following templates below, are general templates designed for conferences using an US Letter (8.5" x 11") trim size.
