Re: QUIC, Connection IDs and NAT

It appears that Robert Brockway <robert@timetraveller.org> said:

Does the existence of Connection IDs separate from IP mean that the host/IP contention ratio in CGNAT can be higher? IE, can a single CGNAT device provide Internet access for a greater number of end-users?

No, QUIC runs over UDP which runs over IP. QUIC replaces the TCP sessions that a web browser uses but the device is still doing all of the other IP stuff that it does. I could imagine that the connection ID might slightly increase the load on a NAT since a device might be hopping back and forth between networks, e.g. mobile and wifi, and be considered a new NAT client each time it does.
