传统的一对一的通讯方式不能满足电子教室将一台机器的屏幕广播到多台机器的应用要求,为此设计了基于IP多播技术的Linux下的通讯方式,不但减少了网络带宽的占用,而且提高了传输效率.发送端和接收端均采用Python实现,运输层使用UDP协议,完成了较大规模的测试,弥补了Linux下没有电子教室应用的空白,具有一定的实用和推广价值.

Traditional point-to-point communication fails to meet the screen broadcast in electronic classroom, as there is many receivers. An IP multicast technology based communication is introduced in the Linux electronic classroom. It is, not only saved network band width, moreover is high efficiency. Sender and receivers, which are implemented by Python, are tested. This electronic classroom fills gaps in Linux, and has a great practical value.
