FTP协议是一种基于TCP/IP的文件传输协议，用来在网络中进行文件传输。FTP是TCP/IP的一种具体应用，它工作在OSI模型的第七层，TCP模型的第四层上，即应用层，使用TCP传输而不是UDP，FTP客户在和服务器建立连接前就要经过一个“三次握手”的过程，它带来的意义在于客户与服务器之间的连接是可靠的，而且是面向连接，为数据的传输提供了可靠的保证-FTP protocol is based on TCP/IP file transfer protocol that is used in the network for file transfer. FTP is a TCP/IP to a specific application, it works in the seventh layer of OSI model, TCP model for the fourth layer, namely, the application layer, using TCP transport instead of UDP, FTP client and server must establish a connection before the After a "three-way handshake" process, it brings the significance of the connection between the client and the server is reliable, but also connection-oriented, for data transmission to provide a reliable guarantee for
