iBoard Design Highlight

• Traditional C/S and B/S Architecture
• Disadv.Over-Rely on server,Less flexiblity
• Advan.Easy to Manage, High efficiency

• Peer-to-Peer Networks
• Disadv.Difficult to manage,low reliablity
• Advan.Flexible,Independent .etc

• iBoard
• Combine both advan. Independent, flexible and
  reliable.

5
iBoard Design Highlight

• Still use Host (Super Peer) to manage member
• Transmit message
• Update member information
• Member are not completely relying on Host
• There is a candidate in the group, and update
  in time
• The members are not affected when the current
  host are leaving
• Every member could be the Host!

Future Work

• Improvement on System Architecture
• Use Room ID to connect to a hosts room instead
  of using IP address. It will greatly increase the
  flexibility of the system.
• Implement the communication between rooms.
• Improvement of the detail
• In graphic component,to improve the previous
  drawing technique, and allow the self-adjust of
  the picture.
• In messaging component,to allow font choosing,
  setting and displaying.
• In networking component,to support proxy
  connectionalso voice communication.

17
Future Work(2)

• Adapt UDP
• It is more flexible, I can design the new
  protocol according to the requirement.
• Nevertheless, difficult to implement (working on
  it)
• Add more features
• Voice and video conference.
• Collaborative Exploring (PDF, WebPage)
• Sharing Resource
