TFTP simple Text Transfer Protocol and BOOTP bootstrapper protocol

TFTP protocol

TFTP 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 order to allow multiple customers to conduct system boot concurrently, TFTP implements concurrency by assigning a port number to each customer.

The TFTP protocol does not provide security.

BOOTP Bootstrapper Protocol:

In the ARP protocol said can be rarp to obtain their own IP, but this can only obtain an IP address, and the subnet must exist under the RARP server.

The BOOTP bootloader protocol uses UDP and TFTP to boot the diskless system.

A router can act as a proxy for a true BOOTP server, forwarding a client's BOOTP request to a true BOOTP server located on a different network.
