> Basically, any software that assumed 1 connection maps to 1 file descriptor, is going to have to be rewritten. Yeah, but I don't think that's a hard thing to do, realistically speaking. Instead of mapping a source ip/port to a destination in the LB it's mapping a QUIC session ID instead. > This also means the kernel, which could previously steer traffic to a connection onto a single core. Most likely the kernel will not be rewritten to support this, since QUIC is a user space protocol. Also, the LB might just be able to rewrite the packet so it looks like it came from the LB when it sends it on to the server. The end server would never see the ip address change.
