摘　　要：对于上层应用来说,用户数据报协议(User Datagram Protocol,UDP)是一种不可靠的无连接协议。它不能为数据发送提供保障,且数据在传输过程中可能丢失或者被篡改,到达对端也是乱序的。但是,UDP传输速度高,具有高效性。因此,基于UDP协议设计了一套可靠的高效控制系统,并利用Java语言进行了实现。结果显示,用这套系统传输一个76 MB的文件仅用了29 s。此外,设计了一个类似的系统来测试写卡器的稳定性,结果测试10000次全部成功,证明这套UDP传输系统具有高效性和可靠性。User Datagram Protocol(UDP)is an unrelieable,connectionless protocol for application.There is no guarantees for data transimittion.Data can be losted or changed,and arrive out of order.But UDP has a high transport speed.We wanted to use its highefficiency,so we design a relieable and effective contorl system worked on the UDP,and realize this system by Java.We use this system to transport a 78 MB file used 29 seconds.We design other similar system to test a card-writer’s stablity for 10000 times,and all are successful.Because of these tests,we believe that this transport system based UDP is high-efficiency and relieable.
