You design a new transport-layer protocol XYZ that improves performance over TCP. However, XYZ requires changes to many applications and also breaks on many NATs/firewalls unless they are upgraded. Only a small fraction of networks adopt it, and most traffic stays on TCP/QUIC. Which EvoArch explanation best fits this outcome?

A learning bridge (Ethernet switch) starts with an entirely empty forwarding table. Host A (source) sends a frame to Host B (destination), and the frame arrives on the switch at port 3. What does the switch do first to “learn”?
