| Abstract: | Based on a deep research on electronic white-board,an electronic whiteboard system based on P2P technique which is suitable for the real-time online communication between teacher and students is discussed.The system adopts B/S-based architecture and modularized organization.For multi-user concurrency control,a lock scheme is used and the multicast technology is also used to improve efficiency of interaction and achieve consistency of the state.And implementation of network communication is based on TCP/IP and UDP protocols at the same time,which can improve transmission efficiency of the electronic whiteboard. |
