TFTP (Trivial File Transfer Protocol)

TFTP (Trivial File Transfer Protocol)

TFTP stands for Trivial File Transfer Protocol. TFTP is defined as a protocol that is used to transfer a file from a client to a server and from a server to a client. TFTP is majorly used when no complex interactions are required by the client and server. The service of TFTP is provided by UDP (User Datagram Protocol) and works on port number 69. TFTP does not provide security features therefore it is not used in communications that take place over the Internet. Therefore it is used only for the systems that are set up on the local internet. TFTP requires less amount of memory....

Working of TFTP

TFTP makes use of port number 69 as it uses User Datagram Protocol (UDP). When the connection is established successfully between client and server, the client makes a Read Request (RRQ) or Write Request( WRQ). If a client wants to only read the file it requests RRQ and if the client wants to write some data into a server then it requests for WRQ. Once the connection is established and a request is made communication of files takes place in the form of small packets. These packets are 512 bytes each. The server then communicates the packet back to the client and waits until it receives an acknowledgment from the client that the packet has been received. When the acknowledgment is received from the client side, the server again sends the next packet which is 512 bytes each. The same steps as mentioned above continue until the last packet is sent by the server to the client....
