[ NNSquad ] Re: [IP] BitTorrent uTorrent 2.0 uTP will self-throttle to protect networks


Update 7:24PM

 

I’ve contacted BitTorrent’s engineers and they have posted a response here (in comment section).  Note that they do not contradict any data in here.  They don’t even claim to address the fact that BitTorrent will hog 10 times or more bandwidth due to the multi-flow aspect of BitTorrent.  The only thing they’ve said in email to me with regard to bandwidth usage was that “use of idle bandwidth was a design objective”.  The problem that they’re not just using “idle” bandwidth; they’re taking away a lot of bandwidth from other applications and other users and taking a much bigger piece of the pie (as shown in figure 1 above) than justified.

 

About the only thing BitTorrent claims is that the new uTP protocol tries to keep upstream jitter to less than 100 milliseconds which is still way too high for online gaming and even my Lingo VoIP telephone service.  The downstream jitter is admittedly much greater.

From the looks of it, it seems that people are reading too much into the claims that the new BitTorrent protocol is “network friendly” and that it somehow obviates the need for smarter network management.  From the data that I have collected and from BitTorrent’s response, these claims appear to be greatly exaggerated.
