It should be possible to distinguish this by looking at the three-way handshake at the start of the connection. This will show a different set of TCP flags and ECN field values depending on whether RFC-3168 or AccECN is being attempted. Without AccECN, you won't have functioning L4S on a TCP stream. But I think it is more likely that it's a misapplied DSCP. - Jonathan Morton _______________________________________________ Bloat mailing list Bloat@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/bloat
