TFTP simple Text Transfer Protocol and BOOTP bootstrapper protocolTFTP protocolTFTP primarily uses the UDP protocol, which requires TFTP when a program or file needs to be downloaded to many machines at the same time. Or when the diskless system is working, a TFTP request is broadcast, and the TFTP server on the network sends a response that contains the executable program that relies on the diskless system to execute the program.At the same time, in

Group of less than 512 bytes, it will know that it has received the last data group.When writing a request, the TFTP client sends WRQ to specify the file name and mode. If the file can be written by the client, the TFTP server returns an ACK packet with the block number 0, and the client sends the first 512 bytes of the file with the block number 1. The server returns the ACK with the block number 1.The data transmission of this protocol is called the Stop wait protocol.The last TFTP packet typ
