Fwd: Internet operations during pandemics
by Christopher Morrow 23 Mar '20

23 Mar '20

Did other folk on nanog-l see the nLnog-l note copied here? I wonder how folk are planning for things (noted in the slides) o supply chain for parts/equipment Wait, I can't get me a new shiny shipped because what?? o ongoing rollout of new equipment I'm deploying next week in KIX, I'm currently in LAX how do I get there? equipment arrives.. in between...oops! o noc/etc support staff omg.. wait, I can't have my noc staff in the same room? our 'wfh' solution is ... wait, where is that? how do i get their phone queue sent to them? omg :( <sadness!> o services capacity crunches I love my shiny new dns service.. .wait, why is there a smoking hole where my dns servers were? I think some of this has been discussed (shifts in peaks, leveling of peaks) Some hasn't really... I expect that at least sharing some 'err, our WFH changed now we do: X, Y , Z and use M to get N solved' could be super cool to discuss/share and iterate for better solutions for all of our users. thoughts? :) thanks! -chris (note all the hard work in this message is not mine... thanks Job!) ---------- Forwarded message --------- From: Job Snijders <job(a)ntt.net> Date: Wed, Mar 18, 2020 at 6:02 PM Subject: Internet operations during pandemics To: <nlnog(a)nlnog.net> Dear all, I threw together a slidedeck today on the potential impact and second order effects of COVID-19 on Internet network operations. http://instituut.net/~job/netops_during_pandemics.pdf I hope we together over time can add and extend projections in the deck on what will happen and how we can mitigate the negative effects on Internet operations. We have to answer questions such as: 1) what problems already exist today because of a few weeks of C19? 2) What problems are still coming? Will those be localized or globally? 3) What possible workarounds can we plan for those problems? I would appreciate feedback, comments, corrections or whatever you want to tell me. None of us have been in this situation before, so my guess is as good as yours. Kind regards, Job

Sunday traffic curiosity
by Andy Ringsmuth 23 Mar '20

23 Mar '20

Fellow NANOGers, Not a big deal by any means, but for those of you who have traffic data, I’m curious what Sunday morning looked like as compared to other Sundays. Sure, Netflix and similar companies have no doubt seen traffic increase, but I’m wondering if an influx of church service streaming was substantial enough to cause a noticeable traffic increase. We livestream our services and have been for about a year or so, but normally average just a handful of viewers. Today, we were around 150 watching live. ---- Andy Ringsmuth andy(a)andyring.com

There are about 20 years of archives to weed through, and some of our friends are still trying to make this happen. I expect someone (Hi Lenny) to appear any moment and mention AMT. So my take isn't universally accepted, but it won't be too far from what you'll hear from many. Brief summary off the top of my head: 1. Complexity. Both in protocol mechanisms and the requirements in network devices (i.e. snooping, state, troubleshooting). 2. Security. Driven in part by #1, threats abound. SSM can eliminate some of this and you can design a receiver-only model that removes most of the remaining problems - congratulations you just reinvented over the air broadcast TV. Even if you don't do interdomain IP multicast, you still may be at risk: <https://ccronline.sigcomm.org/wp-content/uploads/2017/01/p27-sargent.pdf> 3. Need and business drivers. Still far from compelling to build and support all this to make it worthwhile for all but a few niche environments. Support and expertise in this area is also very thin. Your inquiry demonstrates this. I stopped teaching it to students. What remains is becoming even less well supported than it has been. There is almost no interdomain IP multicast monitoring being done anymore. There is scant actual content being delivered, all the once popular stuff is gone. The number of engineers who know this stuff are dwindling and some that do know something about it are removing at least some parts of it: <https://tools.ietf.org/html/draft-ietf-mboned-deprecate-interdomain-asm-07> John

China’s Slow Transnational Network
by Pengxiong Zhu 22 Mar '20

22 Mar '20

Hi all, We are a group of researchers at University of California, Riverside who have been working on measuring the transnational network performance (and have previously asked questions on the mailing list). Our work has now led to a publication in Sigmetrics 2020 and we are eager to share some interesting findings. We find China's transnational networks have extremely poor performance when accessing foreign sites, where the throughput is often persistently low (e.g., for the majority of the daytime). Compared to other countries we measured including both developed and developing, China's transnational network performance is among the worst (comparable and even worse than some African countries). Measuring from more than 400 pairs of mainland China and foreign nodes over more than 53 days, our result shows when data transferring from foreign nodes to China, 79% of measured connections has throughput lower than the 1Mbps, sometimes it is even much lower. The slow speed occurs only during certain times and forms a diurnal pattern that resembles congestion (irrespective of network protocol and content), please see the following figure. The diurnal pattern is fairly stable, 80% to 95% of the transnational connections have a less than 3 hours standard deviation of the slowdown hours each day over the entire duration. However, the speed rises up from 1Mbps to 4Mbps in about half an hour. We are able to confirm that high packet loss rates and delays are incurred in the foreign-to-China direction only. Moreover, the end-to-end loss rate could rise up to 40% during the slow period, with ~15% on average. There are a few things noteworthy regarding the phenomenon. First of all, all traffic types are treated equally, HTTP(S), VPN, etc., which means it is discriminating or differentiating any specific kinds of traffic. Second, we found for 71% of connections, the bottleneck is located inside China (the second hop after entering China or further), which means that it is mostly unrelated to the transnational link itself (e.g., submarine cable). Yet we never observed any such domestic traffic slowdowns within China. Assuming this is due to congestion, it is unclear why the infrastructures within China that handles transnational traffic is not even capable to handle the capacity of transnational links, e.g., submarine cable, which maybe the most expensive investment themselves. Here is the link to our paper: https://www.cs.ucr.edu/~zhiyunq/pub/sigmetrics20_slowdown.pdf We appreciate any comments or feedback. -- Best, Pengxiong Zhu Department of Computer Science and Engineering University of California, Riverside

I agree. Related to copyright and patent restrictions, is this: Currently the situation is that I cant get to see the ARN (acid rybo nucleic) sequence of this virus; the data is present on gisaid.org, situated in Germany, at MAx Planck Institute, but my request to see it did not succeed - silence. FRiends tell me that silence is normal because I am not a specialist, and those who are specialist do have access. I disagree. I want to know what it looks like. This virus with a crown might hurt me as much as it might hurt the specialists, there is no difference, we are all Sapiens. I want to know what it looks like. The only thing I could find is during a TV news report, see below. That sequence of A, T, G, C, and their particular ordering, is what makes it bad bad. That's the enemy.

This: https://coronavirustechhandbook.com/home is a super useful resource in my opinion. They are using Google Docs because it provides a really accessible way of doing content creation but hitting capacity issues. Are there any Google contacts here who can get them talking to the right people please? Message me offlist and I will update here when sorted. -- Rob Pickering, rob(a)pickering.org
