Dexter, Are high bitrate streams from mobile devices really a big concern? I would think most devices would communicate the device type either by user-agent or the platform specific app and the stream provider would have built in the intelligence to optimize the stream size.
While wanting to deliver the best experience I think content providers are also faced with the problem of bandwidth expense and would look anywhere and everywhere to lighten the load, hence adaptive bitrate streams. This also goes back to the user experience issue. Netflix knows that trying to stuff a 4k stream through a weak wireless signal on a phone will likely provide a crappy user experience at a higher cost and therefore have built-in the adaptability to provide the best quality that is appropriate for the receiver which often means lowering the bitrate. (PS, I’m curious about your experience with those shapers, the PS10000 here is quite long in the tooth) Jason Watts | Senior Network Administrator PRATT INSTITUTE Academic Computing > On Mar 24, 2015, at 11:32 AM, Dexter Caldwell <dexter.caldw...@furman.edu> > wrote: > > I’ve testing a Procera right now, along with an Exinda. > > One nice thing about the former, it can do device profiling/fingerprinting- > so in theory, you could probably build a set of policies that effectively > said for a phones, you want to squeeze bandwidth down so that smaller > screens, don’t ever pull an HD or say 4K video stream when they become more > prevalent.
