RE: [WIRELESS-LAN] netflix question
We haven't made any caching decisions as yet, but have spoken to Qwilt a couple of times about their product and think it looks promising. Jeff's and subsequent NetFlix SSL information looked like a question that needed to be asked. Qwilt gave a reassuring reply and sent a link to a webex where they should be discussing the Netflix announcement and other caching concerns impacting universities. I read the list emails- I seldom question or comment. So I don't know if it would be OK to toss the link out. But if anyone wants it, I can email them. And if it's OK to just post it here for the curious, I can do that as well.

Re: [WIRELESS-LAN] netflix question
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.

RE: [WIRELESS-LAN] netflix question
To Peter's question, ordinarily for no- high bitrate to small screens is not always an issue- except perhaps in a tight situations such as where you peak your wire speed and need to start intelligently trimming to save business app performance. For the most part adaptive bitrate does work, well, unless you add bandwidth suddenly and the upscaling overwhelms your other hardware that doesn't scale to that throughput yet, resulting in dropped packets. Shaping to smaller screens might might add up if you weren't caching. Moving forward, I've been starting to look more at the intelligence and metrics we can get for planning versus simply managing any given application or IP address. For example, should I invest in IPTV? What devices are users consuming video on? How many devices are there? How fast are they growing in number? How can we scale in the mobile world (wifi) and manage for increased client density, flatter networks smaller chokepoints and more, yet thinner uplinks (Aps) if my infrastructure investments don't keep up. That said I don't like to over-manage bw per se. I let them go for the most part except for a few things I need to shape unless there is a problem. Better insight about personal devices from all network systems for me helps inform a number of other decisions. (MDM, for example, guest management, site design, or investments in wired infrastructure to name a few.) Jason, so far I like both devices, but they are very different. I am by no means an expert on either; far from it. Nevertheless, from what I've seen, Procera is a different idea than you're used to with the PS1. Exinda is very much the same as your PS10K in terms of how it's managed- just a different interface and a few differences in information provided. Procera is more flexible, I think, but a higher learning curve and I feel it's easier to do something you didn't mean to do- either by bad policy config, or by accidently dragging and dropping a whole set of objects someplace it doesn't belong. Also, in Procera, something can match a policy multiple times, for example. It's not necessarily bad, just different. Procera is not for the faint of heart, but it's powerful once you know how to use it. Both when setup seem to be pretty much set and forget and both are worth a look. Right now, Procera scales to higher throughput, but I think that's a short-term issue unless you require much more than 10G today. Exinda is fast and easy to setup, and pretty much what you see is what you get in terms of reporting etc. If I'm wrong about any of this anyone with more experience can correct me.

Dual networks. The premise is that the student pay a fee for connectivity and should get to enjoy the same level of service they would get off campus. Ideally the two networks could use each other's unused bandwidth but I never looked into that.
