Re: [OOL] is punishing encrypted YouTube straems at prime time?

Inside plant does not program the CMTS, but (in a simplistic view) work with the equipment in the head end. I did not know for sure if Inside Plant was in the union, but I didn't care to look as it is irrelevant.

and what do you know: »Why Is Everyone Having YouTube Streaming Issues?

I was slowly making a note of all the YouTube issue topics on this site in each of the ISP related forums to provide in this thread, but I think this news story pretty much sums things up.

YouTube streams are not encrypted. If you go to https://www.youtube.com/watch?v=YIBx0PoSqSg you are only viewing the webpage using SSL. The actual video stream still comes via a non SSL connection from the CDN. This can be verified using WireShark or a similar packet capture software.

There were several threads from Time Warner customer and Comcast Customer less then 2 months ago. Bottom line was youtube can not keep up during anything related to a peak time.

As you can see from the screenshot above, on CV it's ~3mbit, the moment I switch to my work VPN AND STILL DOWNLOAD FROM THE SAME YOUTUBE SERVER I get full 18mbit.
How is that YouTube's problem if they can transfer at full speed?!
VPN connection is encrypted, so CV can't see what's inside and can't throttle it.

Request url is »r18---sn-ab5e6nl7.c.youtube.com/···OMFGcata

OK. I am assuming what you have posted so far is still the same. If it is not, correct the info that I am using that you have posted.

You say the same video with a HTTP request to the site is not throttled. Also you say there is actually no difference between the sending of the HTTP and HTTPS videos other then the request, both videos are sent in the clear. If you read the thread that swintec See Profile posted you will see that CDNs include throttling info in the URLs that fulfill the request. So the likely reason is that the CDN is adding throttling info when you send a HTTPS request.

So then where are you getting "encrypted streams" if none of the video streams are using SSL?

Wrong.
In my last post I said both times I was downloading video from r18---sn-ab5e6nl7.c.youtube.com, aka 173.194.31.87

No, it appears that video streams themselves are still http. I mistaken about that. But since I can't edit thread title, it is what it is.

There's no official documentation that describes what "algorithm=throttle-factor&burst=40" parameters do. Any conclusions are nothing but speculations. It might describe how much to slowdown your download. It might describe how fast to ramp up to your connections' maximum speed. It might describe how fast to download in proportions to the available capacity of a given cluster.
