What is peer-assisted networking?

A website that provides audio and video content can deliver the content with better performance if users playing the same content share their bandwidth. Sharing bandwidth allows the audio or video to play more smoothly, without skips or pauses for buffering. This is called peer-assisted networking, because peers on the network assist each other to provide a better experience.

In addition to sharing bandwidth to improve performance, peer-assisted networking can also enable features, such as chat, that require communication among users of a network or website.
