摘要
通过对现有电子白板技术的深入研究,在P2P技术的基础上探讨了适用于师生实时在线交互的电子白板系统的实现技术。系统采用基于B/S体系结构和模块化组织,通过加锁技术实现多用户并发控制,使用组播技术提高交互效率和状态一致性,并且同时使用TCP/IP协议和UDP协议进行网络通信,提高了网络电子白板的传输效率。
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.
