====CoopNet content distribution system====
'''CoopNet (Cooperative Networking)''' was a proposed system for off-loading serving to peers who have recently [[download]]ed content, proposed by computer scientists Venkata N. Padmanabhan and Kunwadee Sripanidkulchai, working at [[Microsoft Research]] and [[Carnegie Mellon University]].<ref>{{Cite book| last1 = Padmanabhan| first1 = Venkata N.| last2 = Sripanidkulchai| first2 = Kunwadee| publication-date = March 2002| year = 2002| title = The Case for Cooperative Networking (PostScript with addendum)| volume = Proceedings of the First International Workshop on Peer-to-Peer Systems| series = Lecture Notes in Computer Science| location = Cambridge, MA| publisher = Springer| pages = [https://archive.org/details/peertopeersystem0000iptp/page/178 178]| isbn = 978-3-540-44179-3| doi = 10.1007/3-540-45748-8_17| url = https://archive.org/details/peertopeersystem0000iptp/page/178}}  [http://research.microsoft.com/projects/CoopNet/papers/iptps02-with-addendum.pdf PDF (Microsoft, with addendum)] {{Webarchive|url=https://web.archive.org/web/20070417140616/http://research.microsoft.com/projects/CoopNet/papers/iptps02-with-addendum.pdf |date=2007-04-17 }} [https://doi.org/10.1007%2F3-540-45748-8_17 PDF (Springer, original, fee may be required)] {{Webarchive|url=https://web.archive.org/web/20230101095443/https://link.springer.com/chapter/10.1007/3-540-45748-8_17 |date=2023-01-01 }}</ref><ref>{{Cite web|url=http://research.microsoft.com/projects/CoopNet/|title=CoopNet: Cooperative Networking|publisher=Microsoft Research}}  Project home page.</ref> When a [[Server (computing)|server]] experiences an increase in load it redirects incoming peers to other peers who have agreed to [[mirror site|mirror]] the content, thus off-loading balance from the server. All of the information is retained at the server. This system makes use of the fact that the bottleneck is most likely in the outgoing bandwidth than the [[CPU]], hence its server-centric design. It assigns peers to other peers who are 'close in [[IP Address|IP]]' to its neighbors [same prefix range] in an attempt to use locality. If multiple peers are found with the same [[Computer file|file]] it designates that the node choose the fastest of its neighbors. [[Streaming media]] is transmitted by having clients [[web cache|cache]] the previous stream, and then transmit it piece-wise to new nodes.
