Hello, I haven't seen anything to explain this, so I'm asking a larger audience. Did anyone notice any unusual NTT or HE routing this AM?

OK, Google. Time to dial back the AI hype.
by Mel Beckman 30 Jun '15

30 Jun '15

Google has always played fast and loose with its AI claims, but today t has gone too far. In a WSJ story, Google is misleading people into thinking it has achieved emotion, if not outright consciousness, in its AI programming: http://slashdot.org/submission/4569873/wsj-jumps-the-shark-with-ai-gets-tes… Google claims one of its computer programs using a database of movie scripts to answer questions supposedly "lashed out" at a human researcher who was repeatedly asking it to explain morality. Don't computer scientists have a responsibility to deal forthrightly with the public on the real state of research in such fields as AI? When an Internet provider like Google makes such outlandish claims, one has to wonder what the real agenda is. -mel beckman

Call for presentations RIPE 71
by Benno Overeinder 30 Jun '15

30 Jun '15

Dear colleagues, Please find the CFP for RIPE 71 below or at https://ripe71.ripe.net/submit-topic/cfp/. The deadline for submissions is 13 September 2015. 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 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. -- Benno J. Overeinder NLnet Labs http://www.nlnetlabs.nl/

GRE performance over the Internet - DDoS cloud mitigation
by Ramy Hashish 30 Jun '15

30 Jun '15

Good day All, I just want to raise the issue that has not been addressed so far by the DDoS cloud mitigation providers, either in the always-ON solution or the on-demand solution, a BGP session has to be established over a GRE tunnel over the internet between the ISP/NSP/DC and the cloud scrubbing center, the BGP/GRE are used for two main purposes; advertising the victim /24 subnet during the attack, and sending the traffic back to from the scrubbing center to the provider. The question is how can we guarantee the GRE/BGP performance (control traffic) during the time between detection and mitigation? Experts from Arbor, Prolexic(AKAMAI), Radware, Incapsula, Defense.net (F5), Verisign, nexus guard, neustar ......etc are most welcomed to give opinions. Thanks, Ramy "Only the best is good enough"

RE: Thoughts On Cheap Chinese xDSL Testers
by Robert Glover 30 Jun '15

30 Jun '15

The local ILEC (Verizon) use Colt 250+. They are pretty cool. They do not do layer 3 like the meter you referenced. I'm actually looking for a cost-effective meter that does ADSL+ / VDSL2 / e.SHDSL. it's easy to find one that does the first two, but not all three. -------- Original message -------- From: Lyndon Nerenberg <lyndon(a)orthanc.ca> Date: 06/29/2015 5:50 PM (GMT-08:00) To: North American Network Operators' Group <nanog(a)nanog.org> Subject: Thoughts On Cheap Chinese xDSL Testers I've been poking around looking for an inexpensive xDSL circuit tester to do some measurements on my home DSL line, in opposition to the telco. $2K+ is not in the budget, so I'm curious about the accuracy of the $300 Chinese units kicking around eBay (e.g. the ST332B). Anyone out there have experience with them? Are they even remotely close to accurate? --lyndon
