Hello TL, justin.tv worked great for me, but sometimes there was lag, really huge lag, like every 2 seconds -unwatchable. On justin.tv, where you can choose you're bitrate, i was almost always watching streams at 480p. This results in 150-180kb/s download for the stream. The cap for my internet is 200kb/s down an around 20kb/s up. So theoretically it should just work fine, if nothing else uses my bandwidth.
So i was wondering whos fault this lag was. My Internet too slow? Any other programs using my bandwith? Justin.tv? The streamer himself?
I took a look at my resource manager (networking), and always when the lag appeared there was an upload from 10-15kb/s (which uses up 90% of my bandwith).
blue: the stream red: ???
The upload was named under "firefox". so i closed every open tab and deactivated every addon.
The upload stayed. So it has something to do with the stream itself, right? The moment i close the stream the upload is gone.
But why did justin.tv need 90%of my bandwidth upload for wachting (aka downloading) a stream?
the ip is always in between the range: 95.172.94.1 - 95.172.94.255
So i thought: maybe justin.tv uses p2p upload so users are actually streaming while watching the stream, so justin.tv doesnt need so much traffic.
I googled for words like "justin.tv" "p2p" "upload", but found nothing.
95.172.94.72 for example (the bad guy today whiel watching dreamhack) leads to: Network INAP-LON-QUANTCAST-45282
Quantcast:
Quantcast is a media measurement, web analytics service that allows users to view audience statistics for millions of websites. Quantcast Corporation's prime focus is to analyze the Internet's web sites in order to obtain accurate usage statistics by surfers from the USA. wiki-quantcast
So...i dont know, why should this web analytics website needs 90% of my upload? It is coming from justin.tv, because when i close the stream, it's gone?!
From here i don't know what to say, i don't know what quantcast is doing (except lagging my stream)
This maybe only happens to people with slow internet connections like mine. But maybe the upload increases with better connection? I can watch 480p stream without mentionable lag! So I dont acccept this.
Here is a guide to block this Ip range with windows firewall (windows 7):
- Open Windows firewall - Advanced Options
My windows is on german, but using you're brain you will be able to do this:
After blocking Quantcast ips the upload dissapeared, and i can now watch dreamhack, lagfree =)- Until now i didn't noticed any problems occuring, but i don't take any response for this!
So i hope, some of you appreciate this and can now watch lagfree justin.tv. (like is said 12-18kb/s upload isn't much for the most of you, but it can induce lag!)

Cliffs: -Stream lagging -Bandwith is good enough -Unidentified upload (ONLY!) while watching stream blocking my DL rate. -Upload is from Quantcast, but only when watching justin.tv?!

Oh, I'm sorry, i thought it would be ok in the general Forum.
Additional Information: (from wik)
Instead participating websites voluntarily insert Quantcast HTML code inside Web pages they wish to have included in statistics. This code allows Quantcast to keep track of the traffic directed towards those Web sites.[4] Using this mechanism Quantcast can provide thorough details about Web pages created by participating publishers. Some of this information includes, for example, whether the Web page viewer is a male or female, whether the average viewer makes $30,000 USD annually or $100,000 USD annually, the age group of the viewer and the amount of U.S. homes the Web site reaches. This information is provided by inference: comparing and correlating the information received from one participating publisher with another. The inferences are possible because the Quantcast code causes the user's browser to access Quantcast's servers, at which time they can log the user's IP address and information Quantcast places in cookies that are stored in the user's browser.
I don't know, after reading this, i would block quantcast anyway.

Thank you for this! Bloody thing eating up my bandwidth...

Thanks for that information. While I have no problem with lags stuff like this "Quantcast also provides affinities revealing other popular sites that the average viewer browses." is enough reason to block it.

Hey Pharaun,
I also got a very bad connection (125kb down). I watch at 360p, and it lagged the whole time. Now I followed your guide and it's lagfree! Thank you very much!

You're probably uploading data to Quantcast so they can analyze it, pretty much says on the wiki what they do. Also they probably paid the streaming service for this data so perhaps you should keep it on for moral purposes.
Also it's pretty obvious why they need 90% of your upload, its 20kbs.

Jeah sure, you're right. But why should i let it upload so much personal data? 1. I dont want to watch a stream that is lagging! 2. They never asked me or noticed me anyway that personal data is being colelcted and given away (wtf?) 3.Jeah only 20kbs upload, but do you think because of that iam not allowed to watch streams?
I don't understand you're insults.

Maybe noscript is a good idea, block everything but justin.tv and maybe jtvnw.net. It's a good idea in general to use noscript and only allowing sites you trust, and not third party sites and scripts. Add in adblock too with some good filter.
It's likely you need that upload to send tcp-acks back to the justin.tv-servers, if your upload is limited the acks will be throttled and the communication will be messed up.

i have adblock, iam not sure that noscript will block this because if i trust justin.tv the script is in the html code of justin.tv?!
second point: the stream works fine with this ip range blocked, it has nothing to do with the stream itself which runs under "plugin-container" or the ip of justin.tv itself (not quantcast ips).

Okay im not very tech savvy, and was wondering how to do this in windows vista with Mozilla.

yeah you might be correct, saw the ip-range in my netstat now. Might be a good idea to get noscript anyway to block other stuff, a lot of external data collecting stuff that you do not need when connected to a justin.tv-stream. I have 12-14 connections blocked with noscript that fill no vital function for the stream itself.
Now I'm off to block that pesky connection!

Noticeable difference for my stream, thanks for this!

Is there an option to see the connections in Vista?

If you're worried about trackers, you need to also add Ghostery to your arsenal. *Warning - this may add extra work in terms of white-listing...but I believe it is worth it. I had to white-list ESPN.com in Ghostery, for example, to get their VODs to work. You do keep ABP and NS on to block ads and the non-essential scrips on their sites though.

same as win7: Strg+alt+entf ctrl+alt+del (iam so stupid^^) -> Taskmanager-> performance (?)* -> networking
*"performance" or a synonym of that (iam using german windows)

Sorry for bumping, but does anyone know where this static.reverse.softlayer.com comes from? It starts uploading when I open a twitch stream.

I'm bumping this thread for an important reason: Bandwidth theft. Nerds gonna be raging in their seats when they realize whats going on!
OK Guys for along time i have had problems viewing HD streams on twitch.tv. This has been pissing me off alot as it ruined like half the season of NASL for me, as well as the final games i couldn't watch in HQ. I know alot of people are having this lag problem.
What's going on is actually a pretty ingenious yet nefarious plot to sell user data on the internet, and the worst part is there using your bandwidth to do it. I was watching SC2ProLeague and every time i put it to 720 it would start to lag. I came across this thread: http://www.teamliquid.net/forum/viewmessage.php?topic_id=235030 during some research and i started watching network activity.
I noticed first this process open that was sending out a lot of data whenever i had it above 480. Then i noticed that when i switched resolution the connection showed up. Shortly after around 20 other ip connections show up and after sending small amounts of data they disappear. What's left is the original connection with a steady upload. When i switch down to 480 it disappears. I'm pretty sure it is uploading data and then using your bandwidth to distribute it to other sources hence the other connections coming up. This goes away when i switch it down to 480 and initiates again when i switch to a higher data rate.
I downloaded Ghostery add-on for Firefox, disabled all the tracking and now i can once again watch HD streams. Perhaps those of us experiencing this problem have some sort of spyware or virus enabling this flux of data usage, however i was unable to detect it using any software.
