Operator survey: Incrementally deployable secure Internet routing
by Yixin Sun 25 Jan '22

25 Jan '22

Dear Nanog, We appreciate that your time is very precious, but we wanted to ask you for your help in answering a brief survey about a new secure routing system we have developed in a research collaboration between ETH, Princeton University, and University of Virginia. We'd like to thank those of you who have already helped us fill out the survey and provided insightful feedback. Your input is critical for helping inform our further work on this project. Here is the link to our survey, which takes about 10 minutes to complete, including watching a brief 3-minute introductory video: https://docs.google.com/forms/d/e/1FAIpQLSc4VCkqd7i88y0CbJ31B7tVXyxBlhEy_zs… Our architecture, called Secure Backbone AS (SBAS), allows clients to benefit from emerging secure routing deployments like SCION by tunneling into a secure infrastructure. SBAS provides substantial routing security improvements when retrofitted to the current Internet. It also provides benefits even to non-participating networks and endpoints when communicating with an SBAS-protected entity. We currently have a functional prototype of this network using SCIONLab (for the secure backbone) and the PEERING testbed (to make outbound BGP announcements). Our ultimate aim is to develop and deploy SBAS beyond an experimental scope, and the input of network operators that would actually have to run these PoPs would greatly benefit this project and help make secure routing a reality. With kind regards, Prateek, Adrian, and Yixin

Telia is now Arelion
by Justin Krejci 25 Jan '22

https://www.arelion.com/ <sigh> Since all other work is now complete in the world I should have plenty of time to update documentation, billing, labels, port names, route-maps, contact email addresses, etc. After watching their marketing video I learned the pronunciation of Arelion is not R-Lion but is actually A-Ray-Lee-On but I may continue thinking of it as R-Lion because it is shorter and it just sounds cooler in my head.

Re: What do you think about the "cloudification" of mobile?
by sronan＠ronan-online.com 25 Jan '22

It’s the frequency and the knowledge to configure the software and equipment that is still prohibitively expensive in many cases. And frankly, if you are only providing fixed access to 500 users, I’m not sure even the AWS solution is necessary. Because if you can configure the transport and the software you can probably run a handful of KVM servers.

Midcontinent Communications

24 Jan '22

I am looking for someone in network engineering/design at Midcontinent Communications (AS11232) who can explain why the IPv6 PD is set to 64 bits. I believe that this is a poor design decision and would like to understand how this decision was made. Thanks. - Brian

Re: What do you think about this airline vs 5G brouhaha?
by Mel Beckman 21 Jan '22

21 Jan '22

Geoff, My understanding is that the FAA and 5G industry has just this week agreed on buffer zones around 50 of the impacted 80 US airports: https://www.8newsnow.com/news/local-news/las-vegas-airport-included-in-5g-b… The 30 airports that are not buffered I think don’t have 5G deployed yet. For example, Denver international. The buffer zone is described as “the last 20 seconds of flight time”, which considering 230MPH (the airspeed limit in Class C airspace) as a worst case scenario, would be about a mile and a half. I fly helicopters, and for helicopter EMS flying, radar altimeters are important on the RTB (return to base) leg. So unless the FAA can get buffer zones around all the hospital helipads, I think there’s still an issue. There wouldn’t be an issue flying to an accident site, because generally outbound EMS flights required to have much higher visibility minimums, so I don’t think that radar altimeter’s are used in that flight regime. -mel via cell On Jan 21, 2022, at 11:52 AM, nanon08(a)mulligan.org wrote: Jaun says just what I stated previously... in Europe (and my understanding also in Japan) there is an agreement to create a PHYSICAL buffer zone (not just an RF spacing) between 5G transmitters and airport. No such agreement has been made here in the US. So both the RF spacing and physical spacing of 5G in the US is much closer and therefore it is disingenuous of ATT and Verizon to claim "well there are no problems in Europe"! It is not possible to compare the 5G deployment in Europe to the US.

You need a localizer, glideslope, etc. for instrument landings. Radars are made today that can reject out-of-band interference. If FAA simply required a certified radar that filtered out-of-band signals during those weather conditions, the airlines would retrofit and private pilots would also either retrofit, not fly in those conditions, or divert to land in better weather. It's not an FCC issue, and FAA needs to require equipment capable of safely operating within the allocated spectrum. For commercial airlines is it just old equipment or all equipment that has this error? That is, is there actually an off the shelf radio that would solve the problem? Mike
