What does the software do for the file transfer protocol

TFTP (Trivial File Transfer Protocol) - the simple file transfer protocol

The Trivial File Transfer Protocol, or TFTP for short, is a very simple client-server protocolthat regulates the transfer of files in computer networks. A first specification was published in RFC 783 in June 1981. The current standard can be found in RFC 1350, published in 1992. The TFTP protocol uses the likewise minimalist one by default Transport protocol UDP (User Datagram Protocol), which provides for data transmission without a fixed connection between the communication partners. The implementation of TFTP on the basis of other protocols is basically also possible.

The packet-oriented file transfer protocol, which is part of the TCP / IP protocol family, was specially designed so that it as small and easy to implement as possible is. For this reason it only describes methods for reading files or mails from or writing to a server. A listing of directories or the assignment of rights via chmod - as the better known FTP (File Transfer Protocol) allows - are not possible with TFTP. For inquiries uses TFTP port 69. Communication then succeeds via individually assigned port numbers (between 1024 and 65535), which the TFTP server sends to the requesting client in the form of TIDs (Transfer Identifiers).
