TFTP is much simpler than FTP and executes file transfer between client and server processes. TFTP stands for Trivial File Transfer Protocol. After authentication is done, another TCP connection is established for the actual data transfer on another ephemeral port, usually above 1024. When an FTP client requests to connect to an FTP server, a TCP (Transmission Control Protocol) connection is established to the FTP server’s port 21, which is reserved for FTP. FTP handles both binary and text format files. Authentication must be done initially by way of validating username and password and, once complete, files can be transferred between two systems. Control information carries commands and response. One secure version of this protocol is called FTPS, which uses SSL to encrypt data in transit. What is FTP?įTP stands for File Transfer Protocol and it is used to send and receive files from a remote computer.įTP establishes two connections between the client system and the server system, one for control information and the other for data to be transferred. All three protocols are used for file transfer, but there are some significant differences between them. Out of all these file transfer protocols, we’ll be concentrating on three in this blog: FTP, TFTP and FileCatalyst, which uses a proprietary UDP (User Datagram Protocol) based protocol. When it comes time to choose a protocol, there are many options that are still commonly used: FTP, FTPS, SFTP, HTTP, TFTP, among others. It functions much like a language that both ends of the network understand so the data arrives uncorrupted and with a proper file name. Transferring files over the internet is a common task in today’s digital world and it’s important to find and use protocol that fits your organisation’s needs.Ī protocol is a set of rules and messages between a sender and a receiver.
