Re: Netflix CDN Server

I'd disagree. I'd love to have a cache box. Most of my traffic is made up of netflix and people are wanting HD more and more. With the fiber infrastructure in place and operating, my last mile has plenty of capacity to provide to the subs, but it's my connection to the web that's lacking. If i can take that on net, all the better for my subs. That being said, i'm sure there's a minimum to even connect to obtain new content to the server.

Yeah, I wonder how much BW it would take just to keep in sync with every video added to Netflix. I'm assuming it would also have to download a copy of every video in every format, which I'm guessing would make for a lot of downloading.

I think they could schedule it to run between 1am and 6am.
Im not sure exactly how it works but i imagine three streams of 200mb, 700mb and 1200mb for each show x 10 shows per day is only 21 gigabytes.
Even 30 gigabytes a day would still be good i guess. 2 megabytes a second of pre-caching between 1am and 6am. Even if it was spread out through the day it wouldnt be too bad.

I'm interested to see how it turns out for you.

From their documentation:
--
Appliance Fill
For the US Netflix catalog, a fill rate of approximately 5 Gbps for approximately 2 hours
(or equivalent) is currently required. A lower speed link will require a longer fill window.
When multiple appliances are present in a single location, appliances can fill from one
another, reducing the upstream network load.
An appliance updates its cached content nightly with the appropriate content.

The exact
time window is determined for each appliance during the planning process, and is
generally chosen by the ISP as an off-peak period, such as early morning hours in the
local time zone.

So doing a little quick math means that even if you spread it out over 10 hours, that's still a full gigabit for that 10 hour period. Or if you had it update constantly, it would be a non-stop stream of around 415 mbps.

Is that daily though? They don't seem to indicate how often there is a content fill.
