Your ISP may have carrier-grade NAT. The content provider network probably has stateful load balancers. Those devices need to keep state, but they would need to do so with QUIC and UDP quasi-connections too.
- withinboredom 3y agoMost (if not all) ISP routers (outside your business/house) employ connection tracking. This is used to monitor bandwidth usage, implement firewalls (aka, port 25/80/443), among other things.
- oasisbob 3y agoAbsolutely not. Most routers on the internet are not doing connection tracking. But that's not my point - most cases where things /are/ keeping state need to worry about keeping state on UDP-oriented protocols as well.
- tonyarkles 3y agoYeah, 100% agree. The main place that connection tracking is happening is whenever there's NAT involved and that's going to need to happen for both TCP and UDP.
