How we built a new, fast file transfer protocol

Can I tunnel this over SSH and use it the same way as faster drop-in replacement for SFTP? (Why not?)

Standard SSH uses TCP over port 22 by default, so it wouldn't be possible without modifying SSH to use a different protocol. That being said, however, our protocol uses TLS over UDP via the OpenSSL libraries so it is secure by default. We also offer a BSD-style socket interface that you can use if you want a drop in replacement for TCP sockets. Shoot me a note at mahamad _at_ trytachyon _dot_ com if you want to chat!

What's the difference between "TLS over UDP" and Quic? Did you compare your solution to some Quic implementation?

Also, how was CPU usage? In my experience UDP-based stream protocols do signifanctly worse (I assume due to user-space scheduling and unoptimized hot paths). This may be particularly relevant for laptops and mobile.

QUIC is much much more than TLS over UDP.

Ha! Around 4 RFCs and 20 Internet Drafts more: https://datatracker.ietf.org/wg/quic/documents/
