Abstract:
In the existing distance learning system, bandwidth required to transmit multimedia information becomes the choke point. This paper first analyses the limitation of the existing system, then introduces a technology, broadcast in LAN, to improve it. Successful results have been achieved in practice.
摘要: 在现有的远程教学系统中,大量的多媒体信息需求成为系统应用的瓶颈。本文在分析现有系统缺陷的基础上,采用局域网广播技术,对点对点的数据服务方式进行了改进。测试数据表明,改进后的系统数据发送平均时间和服务器吞吐量都有显著改善,而且具有性能不随局域网用户的增加而下降的优点,在实际应用中取得了很好的效果。
