Great blog post! I think your NAT timeout diagram should be showing a changed UDP src port for the final packet heading to the server. You mentioned it changed, but the doesn't actually change in your diagram.

Why do you need it to be backward compatible? Is encryption always-on, and can't be disable? Is it only for HTTP? what about email and other protocols? So, Quic is a replacement for HTTP+TCP+TLS, but runs on UDP?

Would it not have been better to just replace TCP & UDP with a very secure UpToDate protocol? That way anything that runs on them will automatically be secure & encrypted. And don’t make it backward compatible. Make it fully open.

Is that the method you use to protect white supremacist and neo-Nazi websites?

It seems your new at this, or just trolling. However i will bite. It's not there Job to censor speech. When they have attempted to block such things in the past. There was massive outcry that tech companies where censoring there free speech.

there are many difference between UDP and TCP/TLS.. Will QUICK have all functionality of UDP/TCP and combined with TLS?
-
You can think of QUIC as TCP + TLS. Features such as handshake and congestion control are all moved up the stack. The protocol can be iterated faster in user software, rather than at the kernel level. When it comes to HTTP traffic, you can think of QUIC as TCP + TLS + HTTP2

Yes some types of attack can be harder - there’s a section in the blog that deals with some of the possible issues with spoofing and reflection
