  1. TEC BOXTalk Edit Chat Simplified Team 9 Abhishek Jain Keerthy Chavva Mugdha Dharkar Rishit Shroff

  2. What is TECBOX? • Online collaboration tool for document sharing, editing etc • Also text chat and voice chat on the same window

  3. User Interface Invite for Text/Voice Chat Create New Doc

  4. Design Main Server Client 1 Back-Up Server Client 2 Client 3

  5. Bootstrap Process Server Database Look up NS1 Register with NS Back-Up Database NS2 • P2P : • Real Time Editing • Text & Voice Chat • Back-up Server

  6. Collaboration Algorithm

  7. Conflict

  8. Distributed Systems Features • Java RMI as MiddleWare • Multimedia data • Failure handling • Database Replication • Realtime editing

  9. RMI

  10. Failures • Server failure • Client failure • Naming service failure • Database failure

  11. Failure Handling (1) • Server failures Backup Server incase of the server crashing • Naming Server replication • Client failures Heartbeat mechanism Autosave feature • Database Replication

  12. Failure Handling (2) Server Database Back-Up Database • Back-up Server

  13. Other Distributed Features • Text chat • Peer to peer chat • Multimedia Data • Use of java sound • Capturing • Processing • Mixing • Playback audio

  14. Goals Achieved • Realtime simultaneous consistent document editing • Text chat • Audio chat • Convert to PDF

  15. Challenges • Audio Streaming • Java RMI implementation

  16. Future Scope • Undo feature • Text chat conference • Better audio chat

  17. Conclusion

  18. Questions?

  19. User Interface • Login screen for login or registration • Once logged in, user can see his list of docs and corresponding collaborators • User can edit , save and close the document • Also user can chat with the online users visible to him,without changing the windows • Different tabs for different documents

  20. Text Chat and Voice chat • Separate mechanism from doc editing • Peer to peer chat on a separate pop up window • User can select one among online users to chat with • Voice chat • Audio streaming from one peer to another • Java sound – low level support for audio operations like capturing, mixing, playback • Capture sound from the sender, convert to audio data bytes and send over the network • At the receiver side, these audio bytes are read and converted back to soun

  21. How we handle each feature • Multimedia data – Use of java sound -Capturing , processing, mixing , playback audio • Failure Handling- Server failure:Backup Server incase of server crashing(Naming NS replicated, Database cons using SQl) Client server: HeartBeat mechanism, service,autosave 1 min save docs if any changes are made • Database Replication-

  22. Features contd • Realtime editing- Any changes made by the collaborators are relayed in realtime -The document is maintained consistent on all the clients who are collaborators for it -Conflicts in editing the same line are notified to the corresponding collaborators

  23. Features Contd • RMI features:- -Serialization used to marshal and unmarshal parameters -Serves as a middleware
