Small files can be slower to download than from a traditional server as there is an certain amount of time overhead finding peers. Unpopular content can be difficult or slow to download if there are only a handful of seeders. In this regard, it is also a more resilient method as the network becomes resistant to a system failure and does not have any single point of failure once there are multiple seeders. The more peers that want a file, the more peers there will be that have the file to share. The protocol tends to favour more popular content. Initially there will be a single seeder, however once other peers obtain the files they become seeders too. The lack of a central server means that there is bandwidth costs of sharing content is reduced for the originator. A peer is called a seeder if it has pieces available to send out and a leecher if they are still requesting pieces. Peers can send and receive pieces simultaneously from multiple other peers until all peers have the complete file. Each client or peer in the network can then either request a piece (if it is missing it) or send a piece (if another peer requests it).
In order to do this, the files are divided up into small regular-sized pieces. It allows users to directly share files with each other across the internet without any central server acting as a middleman. Building a BitTorrent client from scratch in C#īitTorrent is a protocol for peer-to-peer file sharing.
