I read the abstract of that, and came away with the distinct impression that I wouldn't learn anything from reading the rest of the paper. Not that there *isn't* good information there, but that it's most likely not in a form that I can digest. And that means it's probably impractical to implement on a consumer broadband test. Timestamps - sure, why not - but I don't yet see what you could do with them. > It is possible, with appropriate measurements, to construct arguments that > make marketeers salivate (or the appropriate metaphor) - you can compare the > relative effects of technology, location and instantaneous congestion. See > slideshare at http://goo.gl/6vytmD I'm sure those must be a different breed of marketing types than I have in mind. There are major ISPs who claim that 3% packet loss "is not a fault" - on an idle wire line, not wireless, not congested. They are all about sales and retention by brute force and semi-monopoly position, not by genuinely providing superior service. Hence why we have to turn to the external consumer-oriented organisations, the speed-test sites among them. They will have to serve as *our* marketing tool. - Jonathan Morton _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
