Metalink is an open standard that harnesses the speed and power of peer to peer networking, FTP, and HTTP within a single click. For increased convenience, it stores the multiple download locations for a file (FTP/HTTP/P2P) in a single metafile with the extension .metalink. This provides reliability in case one or many servers fail. Metalinks can also contain checksums to repair downloads and digital signatures, along with other information. Also see the Wikipedia article on Metalink.

Wubi, the Windows-based Ubuntu installer, uses Metalinks to download ISO files.
