A misconception, it was the EU's commissioner for the internal market Thierry Breton (https://ec.europa.eu/commission/commissioners/2019-2024/breton_en) who technically is not a head of a country. And the twitter messaging with Netflix and Co. was the "PR leg" of a joint statement of the EU commission and the Body of European Regulators for Electronic Communications (BEREC)(https://berec.europa.eu/eng/document_register/subject_matter/berec/others/9236-joint-statement-from-the-commission-and-the-body-of-european-regulators-for-electronic-communications-berec-on-coping-with-the-increased-demand-for-network-connectivity-due-to-the-covid-19-pandemic) aimed at european ISPs giving them guidance how to deal with potential congestion due to shifted traffic pattern caused by the mitigation approaches to limit COVID-19 spread. Reading that makes it clear that the EU accepted that in the current situation, the goal is not to let the consumers feel the quality differences between different ISP s but give ISP exceptional temporary permits to shed network load in line with the EU's net neutrality regulation. In a sense the EU was presenting the thumb-screws and laid out under which conditions they might be used. Most of the streaming media companies read the signs correctly and decided to pro-actively reduce their bandwidth use on their own terms, instead of risking indifferent packet dropping by ISPs... IMHO both sides, the political/regulatory and the private enterprises, acted quite rationally and efficient. The fact that there is currently no wide-spread network overload does not make it a bad idea to pro-actively take measures to reduce known bandwidth hogs... Honestly, that is what I expect from halfway decent policy makers, address issues before the house is on fire (but hey, I also consider how the Y2K situation resolved, not to be a sign of undeserved alarmism, but rather successful mitigation after realization of the importance of the issue). > Of course, heads of states with differently aged children > would know that Disney+ or Apple might be other relevant streaming > providers to reach out to, but alas, we have forgotten to elect > those heads of states on such key criteria. Nope, at the time of the twitter message disney+ had not started serving Europe yet, Disney came around promising to pro-actively reduce their streaming bandwidth by 25% even before starting. > > That was of course tongue in cheek of course, but i was somewhat surprised > that nobody took up the opportunity so far to ask something like "how are we > doing on Net Neutrality" ?, or "what the heck would we actually want it to > be" ? Sorry, the joint statement explicitly tackled the issue of how to shed overload in compliance with the EU's net neutrality rules and regulations. Now, you might not agree with the taken decision, but that is different from the questions you posed, no? > > I can see a lot of operational short term workarounds to > approximate solutions less silly than phoning CEOs of random companies, Again, that was the PR side, the "meat" is/was in the clarification to European ISPs how to shed load in compliance with the EU's NN rules. > but it really strikes me as highly strange that events like the > ones we're in right now should not have us re-think to what extend > our current presumed strategy is sufficient beyond workarounds: > > - Best effort is all we need That is not true today, ISPs and CDN's as far as I know already use SLAs to prioritize e.g. VoIP traffic at peering points, so we already have more than best effort for the few things where it matters? > - The Internet MUST NOT be able to further distinguish traffic. IMHO that is a sane approach because traffic carries very little reliable information to meaningfully distinguish traffic. Sure in an ideal world an overloaded hop would divine which packets are least important and target queuing/dropping to those while keeping important traffic fast. Alas, the required oracle seems to be amiss... Also note that NN rules where pushed, because ISPs where playing games with treating traffic differentially with the sole goal of extracting more revenue/income out of the same amount of traffic, is that really what we want? > - Its just a matter of more money to eliminate inacceptable congestion. That hinges on the definition of "inacceptable", but sure money will allow to increase "bandwidth" and hence reduce congestion for the same amount of traffic (or move the point of congestion to some other place). > > Is this what we want to proliferate ?

Hmm... HBO or Showtime ?? Mmh, Showtime only serves the US, and HBO only serves parts of Europe, but assuming you get their content streamed to a receiver in Europe, according to EU commission and BEREC that data could still be subject to throttling (I guess you would need a VPN and hence in practice would avoid being limited). > > Or is the solution really: We MUST only have few big quasi-monopolies, because > our heads of state only have that much time to control Internet QoS through > their phone calls ? No, we have big quasi-monopolies because economists and so-inclined politicians for decades have chiseled away at antitrust regulations... (I find it delicately ironic that the same people who preach "free market" typically are the first that welcome approaches to side-step the market. It is the same "experts" that simultaneously only see limits to what is okay for a company to do by regulations and the law AND work hard to get rid of regulations and laws, but I digress). > Aka: the evolution of the Internet to where we > are today is really a great thing, especially to manage QoS the way we can ? > > Cheers > Toerless > _______________________________________________ OPSAWG mailing list [email protected] https://www.ietf.org/mailman/listinfo/opsawg
