Abstract. CSCW applications require availability, portability, familiarity, scalability, bandwidth and performance. This paper describes the use of Web-multicasting to address these issues. Web-multicasting is a concept that use a standard Web-browser to communicate between multiusers. The web-browser will use multicasting methods, so that no Web server is necessary needed. A prototype Web-multicast Chat System has been developed to test the capability and suitability of Web-multicasting to support collaborative work on web. The prototype was developed using the Java language. The system was implemented using hybrid architecture i.e. client/server and peer-to-peer. Client/server architecture is used for user authentication. Peer-to-peer communication was implemented using multicasting. The benefit for this prototype is multi diverse users can be connected without necessary needs for a Web-server. This paper also describes the extended the three-tier architecture, the prototype impleme...
