摘要
文章通过研究TFTP协议,实现了基于TFTP协议的简单文件传输系统。TFTP服务器端通过采取创建新socket和分配新端口等措施实现了多客户端与服务器的文件传输功能。该系统采用超时重传、socket信息保存、上一条消息暂存等方法解决了丢包、多任务执行等问题,具有一定的容错能力。
On the basis of studying TFTP protocol this paper implement a trivial file transfer system based on TFTP protocol.By taking measures such as setting up new socket and allocating new ports etc.in TFTP server port,the file transfer function between multi-client ports and server.The system adopts some methods such as timeout and retransmission,socket information saving,a message on stage to solve the problem of packet loss and multi-tasking,etc.and has certain fault tolerant ability.
