Cablecom and OVH speed problems since years

by Marco Näf

Hello Everyone I'm having speed problems when I want to download files with my 250mbit Cablecom home connection from OVH. The files are loading with a maximum of 300kb/s. A MTR shows that all data is transfered via a private peering directly from OVH. As it's very difficult to get someone from the Cablecom network departement via telephone or email support and I've seen there are people from Cablecom on this mailing list, I would like to ask someone from cablecom to contact me about this issue at marco AT naefmarco dot ch for more information. Thank you. -------------------------- Best Regards Marco Näf AS201882

Cablecom DS-Lite breaks IPv4 path MTU?

by David Schweikert

Hi, I tried to report this issue to the Cablecom support, but I wasn't very successful... Recently, it looks like my home Cablecom connection was migrated to a DS-Lite setup. I get a public IPv6 address and a private IPv4 address. My IPv4 packets get encapsulated in IPv6, sent to a NATing gateway in the Cablecom network, and NATed there. At least, I have native IPv6 at home now, which is nice, but this is creating various problems for me. The worse one seems to be that path MTU is broken: dws@shuttle:~$ ping -s 1433 8.8.8.8 PING 8.8.8.8 (8.8.8.8) 1433(1461) bytes of data. From 192.0.0.2 icmp_seq=1 Frag needed and DF set (mtu = 1474) From 192.0.0.2 icmp_seq=2 Frag needed and DF set (mtu = 1474) From 192.0.0.2 icmp_seq=3 Frag needed and DF set (mtu = 1474) So some Cablecom router is sending ICMP errors saying that I should fragment the packets to at most 1474 bytes, when in fact I am sending packets that are 1461 bytes long. As you can see above, ping doesn't work at all with path MTU discovery, because the discovered MTU is incorrect. If I manually reduce the size to 1460, it works, so this seems to be the real MTU: dws@shuttle:~$ ping -s 1432 8.8.8.8 PING 8.8.8.8 (8.8.8.8) 1432(1460) bytes of data. 1440 bytes from 8.8.8.8: icmp_seq=1 ttl=58 time=10.4 ms 1440 bytes from 8.8.8.8: icmp_seq=2 ttl=58 time=10.6 ms Do you agree with my analysis that this is a problem in Cablecom's network? Cheers David

Call for presentations RIPE 71

by Marcus Stoegbauer

Hi, preparations for RIPE71 are starting and the Call for Presentations is published. Please see below if you’re interested in giving a talk in Bucharest: 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 71 will take place from 16-20 November 2015 in Bucharest, Romania. 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 71. See the full descriptions of the different presentation formats, https://ripe71.ripe.net/submit-topic/presentation-formats/. Proposals for plenary sessions, BoFs, panels, workshops and tutorials must be submitted for full consideration no later than 13 September 2015. 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://ripe71.ripe.net/submit-topic/submission-form/. - Lightning talks should also be submitted using the meeting submission system (https://ripe71.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.
