It is unfair to lump every individual in an organization together. All orgs have people trying to do the right thing(s), and sometimes, eventually, they win. All that is required for evil to triumph is for good people to do nothing, and docsis 3.1 is entering trials. Some competition still exists there for both modems (8? providers?) and CMTSes (3). My hope is that if we can continue to poke at it, eventually a better modem and cmts setup will emerge, from someone. http://www-personal.umich.edu/~jlawler/aue/sig.html Or one of the CMTS vendors will ship something that works better, although the ARRIS study had many flaws (LRED was lousy, their SFQ enhancement quite interesting): preso: http://snapon.lab.bufferbloat.net/~d/trimfat/Cloonan_Presentation.pd= f paper: http://snapon.lab.bufferbloat.net/~d/trimfat/Cloonan_Paper.pdf I have of the cynical view that it does help to have knowledgeable people such as yourself rattling the cages, and certainly I was pleased with the results of my recent explosion at virgin - 2000+ hits on the web site! 150 +1s!

Given the game theory here, this is why my own largest bet has been on trying to resuscitate the home router and small business firewall markets. covering bets are on at least some ISPs (maybe not in the US) getting it right, on regulation, etc. Forces I am actively working against include the plans juniper and cisco are pimping for moving ISP cpe into the cloud. > It's almost as if the cable companies don't want OTT video or simultaneou= s FTP and interactive gaming to work. Of course not. They'd never do that. I do understand there are strong forces against us, especially in the USA. I ended up writing a MUCH longer blog entry for this, I do hope I get around to getting that site up. > > > > On Wednesday, March 18, 2015 3:50pm, "Jonathan Morton" said: > >> _______________________________________________ >> Cerowrt-devel mailing list >> Cerowrt-devel@lists.bufferbloat.net >> https://lists.bufferbloat.net/listinfo/cerowrt-devel >> Right, so until 3.1 modems actually become available, it's probably best= to >> stick with a modem that already supports your subscribed speed, and mana= ge >> the bloat separately with shaping and AQM. >> >> - Jonathan Morton >> > > > _______________________________________________ > Cerowrt-devel mailing list > Cerowrt-devel@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/cerowrt-devel --=20 Dave T=C3=A4ht Let's make wifi fast, less jittery and reliable again! https://plus.google.com/u/0/107942175615993706558/posts/TVX3o84jjmb
