A distributed interactive virtual classroom system

Interactive Virtual Classroom System (IVCS) is a part of Jiangsu Electric Power Company Network University (JSECNU).This paper describes the architecture and technology of the IVCS, and presents a distributed deployment scenarios of the IVCS based on the enterprise's network architecture, in order to support largescale user access from different regions. With a central dispatch server, login through a dynamic routing algorithm, the system has the ability to load balancing and nearby Login. The program also supports a disaster recovery mechanism, connection loses caused by failure of any of the distributed servers can be restored within a very short time.
