摘　　要：研究一种改进的协同式电子白板系统的设计问题。基于服务器/客户端体系结构,该系统采用阻塞通信方式和多线程网络编程技术,在网络上传输数据包和数据流,实现了一个在局域网中协同工作和交互式的电子白板。针对计算机协同工作的现有并发机制,提出一种改进的并发策略,可以提高通信效率,避免系统通信拥塞。软件测试证明了其正确性和实用价值。This paper focuses upon some aspects on the design ofa cooperativity-improved electronic whiteboard system. Based on server/client architecture, the system transmits data packets and data stream in the network, utilizing blocking communication mode and multithread programming technology. According to the mention above, a cooperative and interactive electronic whiteboard system in local area network is implemented. And it provides a new concurrency strategy to avoid congestion in the network, which improves the present cooperation scheme and promotes communication efficiency. The field trial proves it is feasible and practical.
