TFTP (Trivial File Transfer Protocol) is a simplified file transfer protocol that provides an easy way to download and upload files. Typically, TFTP is used for PXE booting (network boot, diskless workstations, etc.), import/export network equipment configs, firmware upgrades, and some other specific tasks. This protocol has no means of security, authentication, or management. Its main advantage is easy client-side implementation and high performance when large files are transferred. The protocol uses UDP port 69.
