Architecture Overview

The following diagram shows the major pieces of the BigBlueButton architecture.

BigBlueButton Red5 Apps

We think Red5 rocks, and we use it as the core server for handling all the real-time interaction with the client.

BigBlueButton Client

We've written the real-time client in Flash. Since Flash 10, Flash is now available on Mac, Unix, and PCs, and it provides the interface for collaboration with other users.
