No way! You need all the classes at the edge- that is where there is a greatest chance of saturation- where there is a puny t-1 or 2... only one joker uploading his jack-off collection mpg's to his home cable modem pc is enough to kill the mpls site's bandwidth...
So probably the MOST important place to apply qos is OUTBOUND on the CPE for this type of reason... Of course as the SP we will apply qos outbound towards the customer on the PE-CE link...
>do you normally just leave the classification to the edge devices?
Always... the core has enough to do besides classify the customer's junk data... its better to just look at MPLS EXP bits, and perhaps remark some stuff.

Hi Experts,
What do you think of collapsing the classes of service from the edge into
the core?
do you normally just leave the classification to the edge devices?
Thanks
