Thanks Jason.
I've tried to organize them here:

So please send along any interesting traces, any ideas for tests, or
comments!

FYI to this list since I suspect few of you are on the M-Lab Discuss list.
Srikanth from ICSI has kindly taken on consolidating some PCAPs. If anyone wishes to
send any to him, he is at srknt...@gmail.com<mailto:srknt...@gmail.com>.

So it looks as though marking is not done for all MLab traffic. Also, some web
traffic (to CNN) is marked at a lower priority than streaming (Netflix), which
is strange as web traffic is likely more sensitive to degradation than
streaming (?).
Here are the traces:

Another follow-up. Someone emailed me a PCAP off-list from an enterprise type
of customer. Their PCAP was somewhat incomplete (so I still need more) but they
noticed that some traffic at the next priority down from 0x48 at 0x28
(priority). And some other traffic was marked with the next priority down again
at 0x00 (routine).
So it appears there are three DSCP / ToS markings in use rather than just two
(0x00, 0x28, 0x48).
So safe to say more research is needed here – anyone collecting PCAPs should
IMHO continue. :-)
