Speaking of IPv6 performance testing- In a recent FTTH field deployment, the
network operator deployed an IPv6-only network and tunneled all subscriber IPv4
traffic over an IPv6 tunnel to the upstream network edge. It then unpacked the
IPv4 traffic from the IPv6 tunnel and sent it on its merry w

We should call the metric "sucks-less". As in "Box A sucks less than Box B", or
"Box C scored a 17 on the sucks less test".
The actual measurement would be the number of milliseconds of additional
queueing delay when the system is congested, but most people will not take the
time to look und
ost users (particularly people who
care, like gamers) in a manner that got the point across.

Time scales are important. Any time you use TCP to send a moderately large
file, you drive the link into congestion. Sometimes this is for a few
milliseconds per hour and sometimes this is for 10s of minutes per hour.
For instance, watching a 3 Mbps video (Netflix/YouTube/whatever) on a 4 Mbps
ABR folks are still on a
learning curve here.

But the TCP timestamps are impacted by packet loss. You will sometimes get an
accurate RTT reading, and you will sometimes get multiples of the RTT due to
packet loss and retransmissions. I would hate to see a line classified as
bloated when the real problem is simple packet loss. Head of line b

You make some good points. It boils down to the fact that there are several
things that you can measure, and they mean different things.
