Tftp: Server __hot__

Overhead: Each DATA packet requires an ACK (lock-step). Large block sizes dramatically improve throughput, especially on high-latency links.

(e.g., satellite): Use timeout option to adjust retransmission timer. 10. Alternatives to TFTP (When to Not Use It) | Protocol | Advantage over TFTP | |----------|---------------------| | HTTP | Auth, encryption (HTTPS), resumable, caching | | FTP | Auth, directory listing, passive mode | | SFTP/SCP | Full security, SSH tunnel | | NFS | Filesystem semantics, locking | | iSCSI | Block-level access (boot from SAN) | tftp server

(This is a minimal demo; production code requires timeouts, retransmits, and error handling.) | Transfer size | 512-byte blocks | 1468-byte blocks (with option) | |---------------|----------------|--------------------------------| | 1 MB | ~2000 packets | ~700 packets | | 10 MB | ~20,000 packets | ~7,000 packets | Overhead: Each DATA packet requires an ACK (lock-step)
