  3. Main Idea and Functionalities • Main purpose is to provide a collaborative environment for users to interact with each other • Interactions will be via: • Video Conferencing • Audio Conferencing • Text Messaging • White Board (bonus credit) • File Exchange(bonus credit) VConnect

  4. vConnect Web Server DB Video Server Session Mng Svr Session Mng Svr Session Mng Svr Audio Server Regional Users High Level Architecture Figure 1 – The Main Architecture VConnect

  5. High Level Architecture cont’d • Web Server: Authentication of Clients, Querying of the Database, Management of Friends List • Database: Stores the following information: • Username • Password • Status • Friends • IP • Region Information • Server Location Information VConnect

  6. High Level Architecture cont’d • Session Management Server: • Manage connections between clients • Access to Video and Audio Servers for real-time streaming • Quality of Service management • Video Server: Video Stream Processing (mixing, compression, encoding and decoding) • Audio Server: Audio Stream Processing (mixing, compression, encoding and decoding) VConnect

  10. Deliverables VConnect

  11. 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 VConnect

  12. Implementation Plans • Development: J2EE and JMF API • Database: MySQL, JDBC Database Access • Modelling: UML Diagramer • Language: Java • RAD Tool: Eclipse VConnect

  13. Demo Sequences • Web Service and Authentication Server • Session Management Server functionality implementation • Text based chat implementation • Audio Server • Video Server • White boarding • File Exchange VConnect
