shirish said:How are download/upload ratio policies maintained. Are they maintained for their files only or with the overall picture? I use utorrent & the client does produce some statisitics. Are these statistics used by the private tracker to see how good/bad a sharer I'm or it looks for only the files I've been downloading from them?
the above is from wiki...so u see, torrents can very well live without tracker,(if the peers have enables peer sharing).A BitTorrent tracker is a server which assists in the communication between peers using the BitTorrent protocol. It is also, in the absence of extensions to the original protocol, the only major critical point, as clients are required to communicate with the tracker to initiate downloads. (Clients that have already begun downloading also communicate with the tracker periodically to negotiate with newer peers and provide statistics, however, after the initial reception of peer data, peer communication can continue without a tracker.)
