P2P activity accounts for up to 60 per cent of the total traffic
 

Hi!
In a study by Sandvine (http://www.sandvine.com/solutions/pd...WhitePaper.pdf) it reports that P2P activity accounts for up to 60 per cent of the total traffic on any service provider network.

I think this figure is exagerated, and it sow because it interestes them to sell their product. Does any body have any other measures ?

Thanks,

I don't know if it's very exagerated. When you use or browser or send emails, you don't use very much of your bandwith, but when you use a p2p program, you can use 100% of it, and we are talking about a difference of maybe hundreds of Kbps.

being a network tecnician at the university I attend shows me that this number is atcually UNDER exaggerated. we are pushing 80% of traffic at outgoing, gnutella clients.
I haven't been searching much.. but is there any way that we can limit the usage of our schools internet connection, and keep most P2P Local, on the schools LAN? if not, we are going to start Rate-limiting everyone, and if that doesn't work.. start blocking traffic for specific applications (aka, gnutella).

We don't want to stop people alltogether, as I too am one who enjoys getting a song here or there.. but when the network is un-useable for students doing homework or research, something has to go.

If your school has money it can get a traffic manager which can limit peer to peer traffic to a portion of the total available bandwidth.

Otherwise the file sharing apps themselves would need to do this local preferencing. I proposed a local connection idea some time ago in the LimeWire forum but I don't think anyone has taken it on yet.

Sure, it might help get LAN preference for transfers into more of the servents in use. Colleges can just cap P2P since the connection is supposed to be for academic purposes anyway (usually not P2P).

ISPs however are more likely to annoy their customers with P2P restrictions. Even though most people pay a flat rate, remote transfers cost the ISP per megabyte. ISPs are more likely to lose money due to file sharing customers with the greater Internet bandwidth use. It wouldn't be as big a factor if servents preferred local connections for transfers.
