Description/Abstract

We discuss here new distributed computing technologies of relevance for building multi-user scalable televirtual (TVR) environments on the Internet such as: Java Shared Data API (JSDA) by JavaSoft, Common Object Request Broker Architecture (CORBA) by Object Management Group (OMG) and High Level Architecture (HLA) by Defence Modeling and Simulation Office (DMSO). We describe our early TVR prototype based on VRML2 front-end and JSDA back-end, and we summarize our ongoing work on exploring CORBA Events and HLA Dynamic Data Distribution technologies for building scalable collaboration servers for the Internet.
