Trivial File Transfer Protocol
TFTP has a simple design that mimics the deployment, it's easy. The protocol for the transfer of information in the early stages of the boot up through the network like BOOTP , mature PXE mature PSDP and... used. In fact, the TFTP is one of the elements of PXE or protocol boot devices of the network environment that is actually within the BIOS, network card, computer, host, etc., an algorithm to use from those anticipated and institutionalized. From TFTP to transfer the disc image, operating systems, and file sharing configuration to a router, IP phones, and firewalls are also used. The design of this protocol from the protocol EFTP, which is part of the protocol, the PUP is affected . Nowadays, because of the security the bottom of this protocol, it transfers files on the internet is not to be used, and almost the only use of it in the network, local (LAN). TFTP the first time in 1980 by IEN 133 were defined. Then in the following year, in the month of June revise the protocol as RFC 783 is released.
The protocol TFTP, which is one of the most simple protocol, the transfer is using the UDP protocol port number 69. Working with this protocol it is very easy and a lot of settings and features advanced that many of the protocols for data transfer they offer people. This protocol is only for reading and writing information to a remote server or from the remote server is designed and can not change data Name. remove or list.
in comparison with the protocol data transfer TFTP, FTP much easier. For example, in TFTP news of authentication used is not, and anyone who has network access to have it can use it for a while use the FTP authentication importance is high. Of course, the issue of security TFTP reduces. TFTP compared with FTP from a higher speed is also important. The reason for this thread is that FTP when transferring information, the need to acknowledge, packets sent(Packet), but TFTP wait for The acknowledge packets sent remains and file to the next post. Thus its speed is much higher than FTP and can files with high volume transfer.
