Peer-to-peer (P2P) protocol

All of you might have heard of BitTorrent. I think this is the best example to explain the peer-to-peer network protocol.

BitTorrent is a Peer-to-Peer (P2P) protocol designed for distributing large amounts of data over the internet. Traditional downloads often rely on a single server, which can fail or corrupt files. BitTorrent, however, simplifies this issue through its decentralized approach, enhancing both speed and reliability.

In a BitTorrent network, users (peers) share pieces of files, known as packets, with each other instead of depending on a central server. This decentralization allows for different parts of a file to be downloaded from multiple sources simultaneously, making the process faster and more efficient.

To download a file using BitTorrent, a user first obtains a small file called a torrent file. This torrent file contains information about the desired file and the trackers that coordinate the file distribution. Once the torrent file is opened in a BitTorrent client, the user connects to the network to begin downloading and uploading file pieces.

The more users participating, the faster the download becomes, as each user contributes to the file's distribution. This collaborative sharing of resources is a key feature of P2P protocols like BitTorrent, making them efficient for distributing large files to a wide audience.
