World Wide Conferencing Network
WWCN is a system that provides multimedia conferencing services on a world-wide scale. It has been optimized for realtime data delivery: music, voice, video, pictures, text, software updates, and so on. To cope with today's bandwidth scarcity, it implements a reliable "multicasting" technology (one to many data communication) over standard TCP (internet) connections.

World Wide Conferencing Protocol
There are several internal and unpublished documents that describe the protocol and its inner workings. These documents are slowly but steadily rewritten into IETF style drafts, that will eventually be submitted to the RFC editor.On this page you can find three types of specifications:
- specification of the protocol message formats in BCNF;
- specification of the behavior of a protocol entity upon reception of each of the protocol messages;
- both combined in a Request For Comments document (RFC).
Publications
A paper explains the system architecture and protocols used for (mesh) routing, transport, and the (chat) application layer.Behavioral specifications
