Deliverables
VConnect
System Features Location-Independent architecture (Applet-
Based) QoS Enabled Fault Tolerance by primary-backup approach Availability achieved by multi-broker
architecture Audio/Video Processing done on different
servers to achieve modularity and fast processing
Scalability achieved by replication of servers and regions
