By monitoring the download rate obtained from its current set of peers and randomly trying other peers to see if faster peers are available, a client can maximize its download rate. This tit-for-tat mechanism automatically locks out peers who are unwilling to upload themselves. If so, the contacted peer sends a few blocks of the negotiated piece, and continues to do so as long as the other does the same.
With this piece in hand, the peer starts to contact other peers in the list to see if they will trade its piece for another part of the file. Next, the peer contacts a random peer to obtain a first piece of the file itself. The peer then contacts the tracker to obtain a list of peers currently involved in downloading the file, implying they have pieces of the file to share. The metafile gives the peer the address of a tracker for the file and checksums to verify downloaded parts of the file.
#TRIBLER WIKI TORRENT#
A peer wishing to download a particular file through BitTorrent first needs to obtain a torrent metafile for the file from, for example, a Web site or RSS news feed. “BitTorrent has an interesting design that enables each individual downloader to maximize his own download rate and locks out users who do not contribute to the system. A bootstrap point (tracker, DHT node) will also be needed to help users learn about each other. In order to use this technology, one needs to use a BitTorrent client. That's the reason why BitTorrent many times works even faster than ordinary HTTP/ FTP.
The BitTorrent Network offers a solution: customers help distribute the content. The HTTP/ FTP downloading method has a problem: more customers require more bandwidth on the server side. While downloading, clients will simultaneously upload already downloaded data to other BitTorrent clients interested in that data. BitComet is a C++ BitTorrent client running on Windows, compatible with BitTorrent along with many enhancements.īitTorrent is designed to facilitate file transfers among multiple peers across unreliable networks. BitTorrent is a peer-to-peer file-sharing protocol designed by Bram Cohen, and a family of of BitTorrent compatible clients (software) support this p2p protocol.
