What is Metalink?

Metalink lists mirrors, P2P, checksums, and other metadatain an XML format for programs that download.

Previously, gathering mirrors and manually adding them to download managers was time consuming and frustrating.

◦ Metalinker has the solution. It works like this, the .metalink file tells your download manager where it can get the file, and connects to these different sources at the same time.

Having access to more mirrors increases reliability, and speed, as multiple mirrors can be downloaded from at once.

User can download a segment of each file from multiple

servers at the same time. The segments are then added

together when they have all finished.

Features of Metalink

If one server fails, download

automatically resume using

another.

Minimizes and distributes traffic

of individual servers for less

strain.

Combines FTP and HTTP with optional Peer-to-peer (P2P, shared bandwidth).

No Single Point of Failure like FTP

or HTTP URLs. More fault

tolerant.
