== Agenda == The agenda will be set after the workshop submission deadline, 1st of May. We will try to keep a maximum of 4 hours of talks per day, including breaks. == Proposed workshops == === DIY ISP Meeting === Meeting of diy-isp from all over the world. We would like to continue our discussion that started at the [[https://events.ccc.de/congress/2013/Fahrplan/events/5391.html|30C3]] and [[https://fosdem.org|FOSDEM]] and see how we can grow as community and share our knowledge about all the topics involved in changing the internet landscape. * [[https://www.diyisp.org|Diyisp.org Project wiki]], [[https://pad.ilico.org/p/ks7eIHgrej|Pad with notes from the FOSDEM meeting]], [[https://pad.lqdn.fr/p/diy-isp-30c3|Pad with notes from the 30c3 meeting]] * Length: one to two hours * Requirements: a place for 15+ people and a projector would be nice === BATMAN developers community meeting === Batman-adv users (wireless communities, commercial projects or other) may present their way of using batman-adv in real world setups to the present developers and batman users. The goal is to foster exchange about where and how batman-adv is used today, what are the challenges / difficulties while doing so and what can be done to further improve batman-adv. * [[http://www.open-mesh.org/projects/batman-adv/wiki/|Batman-adv Project wiki]] * Length: one to two hours * Requirements: a place for 15+ people and a whiteboard would be nice === Troubleshooting MTU problems on IPv4 and IPv6 networks === Ninux Roma is a Native IPv6 network with legacy support to IPv4. Usually we expect 1500 bytes of MTU and a boring NOC life. Unfortunately life is different. All kind of tunneling (VLAN, GRE, TINC, MPLS) are deployed on the Internet, eating bytes out of the MTU. Some mesh routing protocols use tunneling techniques themself. IPv4 packet fragmentation introduces bad performances but a working IPv4 end to end connectivity even if some link have a smaller MTU than needed. In the IPv6 Internet a MTU problem can blackhole your traffic. In this talk we will see some well known tools (ping6, radvd), and we will understand how to use them to check the end to end MTU. * Length 40 minutes + questions. * Requirements: Projector. == Social events == Thursday morning: Activity outside of the sublab and without laptops! More details to follow. more to be announced/proposed.
