Re: Netflix takes up 9.5% of upstream traffic on the North American Internet
#2So if Netflix makes up 9.48% of upstream and 32.39% of downstream, that means for each 10 packets sent, 3 ACK packets are sent back (I know those figures don't represent raw traffic). Does that seem a little odd? I'm not asking as a basis for some conspiracy, I'm more so wondering what that implies for data services I'm working on.

no, it just means that you don't have to upload a whole lot of stuff to become 10% of upstream traffic.

#4All this statistic tells you is that upstream bandwidth is ridiculously constrained compared to downstream bandwidth, when TCP ACKs can fill it up to that degree.
Asymmetric bandwidth isn't particularly high on the list of priorities when it comes to the terrible state of the ISP industry in America. It's just "one more thing".

It just seems weird that YouTube is further down that list, yet YouTube is a video hosting service.

#6From the article:
the newest report has Netflix at 9.48 percent of upstream and 34.89 percent of downstream [...] The average Internet subscribing household in North America uploaded 7.6GB of data per month in Sandvine's report in the first half of this year, increasing to 8.5GB in the latest report, a boost of 11.8 percent. The average household's monthly downloads increased from 43.8GB to 48.9GB, a boost of 11.6 percent.
So the average "Internet subscribing household in North America" downloads 48.9GB * 34.89% = 17.1 GB from Netflix, and uploads 8.5GB * 9.48% = 0.8 GB. If the upstream is all 40 byte ACKs, that's one ACK per 850 bytes downloaded, which is a bit more ACKing than I expected, but not completely unreasonable.

No, all this tells you is that there's not much upstream traffic in general. The amount of traffic could be constrained by available bandwidth, or it could be vastly overprovisioned and there's just no demand for it.

#8Anyone know what the equivalent upstream/downstream stats would be for all of cable/traditional tv companies? Most of these articles show how large Netflix is now - I'm curious how large they'll get.

#9Why does Netflix use TCP for streaming instead of UDP? A few missing packets isn't going to meaningfully impact a video stream.

Maybe because it allows them to adjust the quality they're feeding you dynamically based on your bandwidth?
