Outline

OpenCDN is an application-level Content Delivery Network for replication and splitting of live multimedia content and distributed caching of VoD, by deployment of a Streaming Relay Overlay Network. It has grown as an OpenSource project, and can be adapted to any kind of streaming technology. Free participation can be in the form of development and testing, set up of remote replication nodes, and contribution of live feeds.

Goals

When and if the OpenCDN project will be widely endorsed, netcasting to large audiences will become as easy as meeting friends at pub. No ubiquitous multicast routing will be necessary, and TV will become obsolete.
Artistic and cultural events will reach broader audiences, students will attend to courses from home, videoconferences will become Internet talk-shows.

Architecture

OpenCDN is made of the following entities:

Things to do (maybe?)

Future (?)

Development without field trials is almost non-sensic. There can be an egg and chicken problem (no contents without the network, no network without contents), but also pretending that everything works by itself is exaggerate. As an open source project, space exists for contributions in many aspects. For instance, Helix fine-tuning work came mainly by an independent contributor.
