Keep the 10161oo244 for legacy device support (e.g., old RTUs that only speak FTP), but route all human and modern client traffic through a SFTP/HTTP bridge .
"Any FTP server can be tuned to match it." Fact: You cannot software-patch a generic OS to get DMA-based file access or hardware CRC offloading. The ICC server is better by design.
FTP (File Transfer Protocol) is inherently more robust for large file transfers than HTTP (web browsing). If your connection flickers, an FTP client can resume the download exactly where it left off. The 10161oo244 server is optimized for: 4K movies and lossless audio. Software Repositories: Large ISO files and OS updates.
Barcode scanners send small .xml files every 3 seconds. Generic FTP servers maxed out at 150 files/sec. The ICC variant sustained with zero dropped connections.
