Upstream bandwidth is more expesnive than downstream bandwidth partly as you cant cache it at all but simply because of the way that ISPs peer with each other in the data centres. Many routes into your network but only 1 route out so to speak. Routes out mean more companies to peer with which means more cost. This cost is passed onto the end suer in the form of caps. Additionally most home internet conenctions are asyncronous by nature and the hardware cant uplaod as fast as it can download. You want a synchronous connection try and look up a leased line. 10mbit in my area for a 6km line will cost you around £10k/annum rent from BT/C&W. Fait bit more than your £20 month isnt it :) The real reason upstream bandwidth is generally limited is for both technical and financial reasons.

That means that the "big" number the ISP quotes in its advertising gets smaller, and the ISP looks worse compared to the competition. Not enough people are using bittorrent (yet) to make it a sales point, that you might actually get higher BT speeds by making this change. P.S. Greed is never an explanation, because everyone is greedy. Saying that someone does so-and-so because he is greedy is like saying he does it because he breathes air.

So, for example, the ISP which gives 5Mbit down and 256kbit up, the 5-6% of active downloaders (25-30% x 20%) lower the AVERAGE download bandwidth per user to about 256kbit for the whole system. (5Mbit * 5-6% = 250-300kbit). That, and Nathan (reply 1) said, to dissuade residential subscribers from running HTTP/FTP servers, etc. In the United States most residential broadband ISPs give limited upload because

This will require them to use double the bandwidth at the same price. ISP are greedy people, they want you to pay as well as content providers, like google, yahoo, etc.. (since they use bandwidth to send you info) [so what do ISP pay for if that happens?] ISP will not offer symmetric connections any time soon.

The "speed" of the swarm is defined as the combined upload speed, so what you say here is true by definition. However, during the initial seeding, the speed of the swarm will max out on the speed of the seeder(s). You can have 300 people with 1Mbit upstream connections, but if the seeder has their upload capped at 5KB/sec, that's the real max speed until the seed is done. What you say here is reasonable - it's a good idea to get people to uncap their upload bandwidth, since it helps everyone. But, the title of your article may be a little misleading to some people. Increasing my upload speed doesn't affect *my* download speed significantly - it just helps others. “The speed of the BitTorrent swarm will always max out on the combined upload speed”

These are all well and good but even with their enormous amounts of bandwidth they have been designed for the internet of 5 years ago. Back then it was all a one way street - users downloading content such as images and web pages off servers. An internet like this is very well suited to our current forms of high speed connection as users would generally download a lot more than they upload. Now with things such as Bittorrent and the Web 2.0 movement this is becoming more of an issue. Yeah you could go and get 512/512 SDSL (Symmetric DSL compared to Asymmetric DSL that most of us has) but it is expensive and slow. When you look at services such as ADSL2+ the upload speed is way out of proportion with the download speed. [...] [...] Most people nowadays have high speed internet connections like ADSL or Cable.

This mode will distribute as many pieces as possible in the shortest possible time, increasing the availability of the entire torrent. This means that potentially the seeder has the entire file, leecher #1 has the first third, leecher #2 the second and leecher #3 has the third and final piece. There is now a total of 2 copies in the cloud. This means that, hypothetically, you could download at 2x the upload speed of the seeder. This effect gains strength only if seeders are able to further spread the pieces they've downloaded, so that you could hypothetically have many times more the upload speed of the initial seeder. That's why you really need to upload while you download, because if you don't there won't be anyone else getting getting the parts they need to share to others.

Good rational explanation. I always thought that it was about cost of the ISP for uploads not use. If more use was there you would think that the isps would have adjusted the ratio Instead some are limiting bit torrent uploads with software. Small things for small minds.
