If you expect to see only colored packets,
and assuming you do this using DiffServ codepoints,
how would you ever have packets that don't
have any color?  They shouldn't be getting
classified to use the color-aware meter in
the first place.
 
If you're somehow re-classifying new traffic,
then it would be safe to assume it's green 
because you're "blind" to that color...
 
Just my $0.02.

Hi Jay,
 
I am sorry, I didn't make the question clear.  In the color-aware marker,
the metering/marking also takes the incoming color into account.  You don't
want to promote a packet marked with color red to either yellow or green
even if the packet is in-profile.  The question is what if the incoming
color of the packet is neither red, yellow, or green, should the packet be
treated as a red-color packet and should not be promote to yellow/green even
if it is in-profile.
 
Thanks,
-Man

Man,
 
That is the job of your meter/marker. Measure it and give it a color.
 
thanks,

Hi,
 
In a color-aware srTCM or trTCM, how is the incoming data with an
un-recognized color be treated.  Should it be treated as red?
 
Thanks,
