摘　　要：UDP协议具有传输效率高、可扩展性强的特点,适合应用在实时性要求较高且有海量数据传输的场合。文章通过对UDP协议下单播、广播与组播3种通信模式的研究,比较分析了各模式的优点与局限,给出了各模式下网络通信的实现方法;以智能楼宇门禁系统为例,给出了UDP协议各通信模式的嵌入式应用。Due to characteristics of high transmission efficiency and strong expansibility,UDP is suitable for the occasion of massive data transmission and high real-time requirement.Under research of three communication modes of UDP -Unicast, Muhicast and Broadcast, this thesis analyzes advantages and limitations of them,then gives realization of the network communication methods in every mode.Finally taking the embedded entrance access control system of intellectual building as an example,it provides the embedded application of different UDP modes .
