Re: Does Bittorrent check CRC for received files?
said by blah :
Does Bittorrent calculate CRC (I would think it is stored in .Torrent file) and check it when file transmission is completed? Yes. Uses SHA-1 and checks pieces as they come-in then, when torrent completes & reassembles the files, everything is checked again. User can opt-out of the final check but it's not a good idea.
Pando employs the bittorrent protocol but I think it's substantially modified and doesn't talk to BT clients. Not sure about that though. Central servers host content as part of the distribution so it's a fundamentally different approach ... technically & socially.
If your friend & you are wanting 1-to-1 transfers use FTP. Or at least not a distributed bandwidth model. The latter is specifically for distribution from 1-to-many or many-to-many. Both inefficient & transparent. Even if the content is encrypted the connection patterns stick out like a sore thumb on the network. |
