What is a tracker in Torrents?

A BitTorrent tracker is a service on the internet that assists in the communication between BitTorrent clients. When you open a torrent file, your machine contacts the tracker and asks for a list of seeds and leechers to connect to.

A Bit Torrent tracker centrally coordinates the P2P transfer of files among users.
Tracker software serves up torrent files for download from a Web site. The tracker maintains information about all BitTorrent clients utilizing each torrent. Specifically, the tracker identifies the network location of each client either uploading or downloading the P2P file associated with a torrent. It also tracks which fragment(s) of that file each client possesses, to assist in efficient data sharing between clients.

Super-seeding mode in utorrent, vuze, azureus & other torrent clients

Ok, lets learn a term super-seeding seen in torrent clients like utorrent, vuze & azureus. After you have completely downloaded a file through torrent and when a file is new, much time can be wasted because the seeding client might send the same file piece to many different peers, while other pieces have not yet been downloaded at all. Some clients, like ABC, Vuze, BitTornado, TorrentStorm, and µTorrent have a "super-seed" mode, where they try to only send out pieces that have never been sent out before, theoretically making the initial propagation of the file much faster. However the super-seeding becomes substantially less effective and may even reduce performance compared to the normal "rarest first" model in cases where some peers have poor or limited connectivity. This mode is generally used only for a new torrent, or one which must be re-seeded because no other seeds are available.

Torrent, Peer, Seed, Leech, Tracker :BitTorrent Terminology

BitTorrent Terminology

What is Torrent ?
A torrent can mean either a .torrent metadata file or all files described by it, depending on context. The torrent file contains metadata about all the files it makes downloadable, including their names and sizes and checksums of all pieces in the torrent. It also contains the address of a tracker that coordinates communication between the peers in the swarm. Torrents can be downloaded from any of the top torrent sites.

What is swarm?
Together, all users sharing a torrent are called a swarm. Six peers and two seeds make a swarm of eight.

What is peer in torrents?
A peer is one instance of a BitTorrent client running on a computer on the Internet that you connect to and transfer data. Usually a peer does not have the complete file, but only parts of it, however, 'peer' can be used to refer to any participant in the swarm (in this case, also known as a 'client').

What is Seed is torrentz?
A seed is a peer that has a complete copy of the torrent and still offers it for upload. The more seeds there are, the better the chances are for completion of the file.

What is Leech is torrentz?
A leech is usually a peer who has a negative effect on the swarm by having a very poor share ratio - in other words, downloading much more than they upload. Most leeches are users on asynchronous internet connections who do not leave their BitTorrent client open to seed the file after their download has completed. However, some leeches intentionally hurt the swarm to avoid uploading by using modified clients or excessively limiting their upload speed.
The term leech is also incorrectly used to refer to what should properly be called a peer, a member of the swarm who has not yet downloaded the complete file.

Who is Tracker?
A tracker is a server that keeps track of which seeds and peers are in the swarm. Clients report information to the tracker periodically and in exchange receive information about other clients that they can connect to. The tracker is not directly involved in the data transfer and does not have a copy of the file.

What is meant by availability of torrent ?
(also distributed copies) The number of full copies of the file available to the client. Each seed adds 1.0 to this number, as they have one complete copy of the file. A connected peer with a fraction of the file available adds that fraction to the availability (ie. a peer with 65.3% of the file downloaded increases the availability by 0.653).

What is meant by interested in torrent terms?
Describes a downloader who wishes to obtain pieces of a file the client has. For example, the uploading client would flag a downloading client as 'interested' if that client did not possess a piece that it did, and wished to obtain it.

From Mininova Fan's Guide.

Who is choked uploader in torrents?
Describes an uploader to whom the client does not wish to upload. An uploading client 'chokes' another client in several situations:

* The second client is a seed, in which case it does not want any pieces (ie. it is completely uninterested)
* The uploading client is already uploading at its full capacity (ie. the value for max_uploads has been reached)

Snubbed
An uploading client is flagged as snubbed if the downloading client has not received any data from it in over 60 seconds.
