One question: • To correctly utilize NQB for non-L4S traffic, then the DSCP field of the packet header is used, with a DSCP 45 marking, according to Section 4.1 of [I-D.ietf-tsvwg-nqb]. But the majority of traffic is now encrypted, so it seems implausible for a network to try to infer the type of traffic and whether an application could benefit from NQB treatment; this is best left to application developers to determine as they are the experts in the particular needs of their application.

I'm not quite parsing this.

Do you mean the DSCP is encrypted due to VPN tunneling?
