Abstract
In this thesis, we describe our comprehensive design and implementation of a multicast based shared drawing tool called MediaBoard. Like its predecessor, the LBL whiteboard application, wb, its design follows the principles of application level framing and lightweight sessions. Both applications use the Scalable, Reliable Multicast protocol (SRM) to distribute data over the network. But unlike wb, which embeds the networking code in the application, MediaBoard uses a separate SRM framework library and customizes it to achieve application level semantics and thus performance gains. Based on actual deployment experiences --- MediaBoard was used in an "online classroom" at U.C. Berkeley --- we extended the design to improve its usability, provide increased awareness of remote participants, and integrate support for interactive browsing of the drawing space history. The application is also extremely flexible.
