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) V C onnect

High Level Architecture DB vConnect Web Server Session Mng Svr Session Mng Svr Video Server Audio Server Regional Users Figure 1 – The Main Architecture V C onnect

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 V C onnect

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) V C onnect
