OpenCDN is a tool that concerns the development of an application-level Content Delivery Network, suitable for replication and splitting of live and recorded multimedia content.

It is written in Perl, and interfaces a Relay technology (which splits incoming media packets for each downstream flow) with a control plane, allowing for remote control of content delivery. Media distribution is hierarchically arranged among participating Nodes, by the aid of a centralized control unit named Request Routing and Distribution Management (RRDM), also written in Perl.

Content providers can register metadata describing their contributions, and find it distributed by OpenCDN. Communication in between RRDM and Nodes, and in between Nodes, is performed by XML-RPC calls.

Provided that a sufficient number of Relay nodes are scattered in between the source and the destinations, media can be efficiently distributed to a very large number of clients, without severe network and server requirements, actually performing an Application Level Multicast content routing. In particular, first and last mile will be crossed only once.

The code is modular and allows for easy porting to different Relay technologies: the original development was based on Darwin Streaming Server by Apple, and later it has been adapted to Helix Universal Server by Real.
