There is a reason why in the states, Download Accelerator Plus and FlashGet, and all the others got 100's of millions of installs.
It will speed up your downloads. As broadband deployment increased however, these tools had less and less impact (and less and less installs). My guess is that China is in the beginning of this cycle (hence the massive numbers of installs). Regarding duplicate content: The duplicate servers of content exist because quite often with games or popular video, many different sites will offer up the same content. Many content providers, especially popular ones, will want to thwart Xunlei because Xunlei will pull from the popular content provider's servers and use their bandwidth, even if the user didn't go to the popular content provider's site (and see the ads placed there). If the popular content provider doesn't thwart Xunlei, then anybody can create a site with all of the downloads that the popular content provider has, but with the users saturating the bandwidth of the popular content provider. Websites can prevent partial or full gets by Xunlei by identifying and rejecting requests from the Xunlei client. This can be accomplished today by having your webserver look at the HTTP header for User Agent, or look at the referrer field. If Xunlei begins to basically "forge" a User Agent or referrer so that it is not filtered than the sites will have to get more sophisticated and then make assessments based on request patterns, or IP addresses, session variables, tokens or other similar techniques. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Matthew Kaufman Sent: Friday, December 29, 2006 7:31 AM To: theory and practice of decentralized computer networks Subject: Re: [p2p-hackers] Xunlei David Barrett wrote: > Wow, very interesting.

Assuming they're all servers with public IP addresses and reasonable outbound bandwidth, having each client load-balanced to a single specific server and downloading over a single TCP stream is more efficient for the network -- and provides better download performance for the user -- than having multiple TCP streams fight over the same congestion-limited download pipe. The only reason to download from multiple sources simultaneously is the case where upstream capacity of serving nodes is a small fraction of downstream capacity (see: P2P filesharing network where the files are only present on ADSL or cable modem connected user machines), and thus there'd be no way to fill the download pipe otherwise.
