BitTorrent client
A BitTorrent client is a computer program that uses the BitTorrent peer-to-peer file sharing protocol to download and upload files. It serves as the user's interface to the BitTorrent network, allowing participation in swarms linked to specific torrent files or Magnet links. InPulsed Media services clients can use ruTorrent and Deluge to manage their torrent files. IN Pulsed Media (PMSS) Software Stack is included automatic ruTorrent and Deluge installation and setup.
The client's main job is to manage the process of getting file pieces from various peers in a swarm and putting them together. At the same time, it uploads pieces it has already downloaded to other peers in the same swarm, contributing to the network.
BitTorrent clients are available for many operating systems and platforms, including desktop, web, command-line, and mobile devices.
Core Functions
A BitTorrent client performs several key tasks:
- Parsing Torrent Files or Magnet Links: Reads information from a `.torrent` file or a Magnet link to identify content and find trackers or DHT nodes.
- Peer Discovery: Connects to trackers or uses DHT to find other peers in the swarm.
- Establishing Connections: Sets up and maintains network connections with other peers.
- Requesting and Downloading Pieces: Asks for small, fixed-size pieces of the file(s) from connected peers.
- Verifying Pieces: Uses hash checks to ensure the integrity of each downloaded piece.
- Assembling File(s): Combines all verified pieces to form the complete file(s).
- Uploading Pieces: Shares downloaded and verified pieces with other peers who need them.
- Seeding: Continues to upload the complete file(s) to the swarm after finishing the download, becoming a seeder.
Key Components and Interactions
A BitTorrent client interacts with:
- Torrent Files/Magnet Links: The source that tells the client what content to find and where to potentially find peers.
- Trackers: Servers that help the client find peers by reporting who is in a swarm.
- Distributed Hash Table (DHT): A decentralized peer discovery method, often used instead of or in addition to trackers.
- Peers: Other clients in the swarm with whom the client directly exchanges file pieces.
- Swarm: The collection of all peers for a specific torrent.
Common Features
Modern BitTorrent clients often include:
- Bandwidth Control: Allows users to set limits on download and upload speeds.
- Prioritization: Users can choose which files or pieces download first.
- Queuing: Manages multiple torrents by queuing downloads and uploads.
- Encryption: Support for encrypted connections.
- Peer Exchange (PEX): A decentralized way for clients to share peer information.
- Web Seeding: Ability to download pieces from a standard web server.
- RSS Feed Integration: Automatically downloads torrents from RSS feeds.
- Remote Control: Management via a web interface or mobile app.
- Proxy Support: Use of a proxy server for connections.
- NAT Traversal: Techniques like UPnP or NAT-PMP to improve connectivity behind routers.
Types of Clients
BitTorrent clients come in various forms:
- Desktop Clients: Standalone applications with a graphical interface (e.g., qBittorrent, Transmission, Deluge, µTorrent).
- Web-based Clients: Run as a service, managed via a web browser interface (e.g., ruTorrent).
- Command-line Interface (CLI) Clients: Controlled via text commands, suitable for servers or automation (e.g., rtorrent).
- Mobile Clients: Applications for smartphones and tablets (Android, iOS).
Legality and Usage
BitTorrent clients are tools for the BitTorrent protocol. Their legality depends on the content being shared. They are used for legitimate purposes, like distributing large open-source software (e.g., Linux ISOs) or public domain content. However, they are also widely used for unauthorized sharing of copyrighted material, which is illegal in most places.
Users are responsible for ensuring that the content they download and upload is legally obtained or distributed.
