| Peer5 operates the world’s largest peer-to-peer (p2p) content delivery network. Peer5's P2P CDN improves content delivery for live and on demand video streams. As video streaming continues to become more mainstream and the streams themselves become HD and 4K, traditional CDNs struggle to deliver high quality viewing experiences. Manypublishers try to keep up with peak demand by paying for more servers, many of which are almost never used and struggle with video playback. Not only is this expensive, but it's also inefficient, which is why at Peer5, they have created a P2P CDN to boost your video streaming capabilities. | Angel / Jul 22, 2014 | ||
