CoolStreaming is a P2PTV (peer-to-peer television) technology that enables users to share television content with each other over the Internet. The technology behind CoolStreaming is similar to that of Bittorrent. The viewers upload content at the same time the programs are downloaded and viewed. CoolStreaming creates a local stream on localhost and that stream is then read by Windows Media Player, Real Player or other media players. The original coolstreaming code is developed with Python 2.3 on Windows. The term P2PTV refers to peer-to-peer software applications designed to redistribute video streams on a p2p network, typically TV stations across the world. ...

Coolstreaming is a data-centric design of peer-to-peer streaming overlay. Notable features of the protocol include its intelligent scheduling algorithm that copes well with the bandwidth differences of uploading clients and thus minimises skipping during playback, and its swarm-style architechture that uses a directed graph based on gossip algorithims to broadcast content availability. An overlay network is a computer network which is built on top of another network. ... It has been suggested that this section be split into a new article entitled Scheduling (communications). ...

Coolstreaming is the first P2PTV system that attracts a remarkable amount of clients (over 1 million, while most of the previous systems attracted less than 1 thousand clients).
