To manage the unfairness of the traffic at the very first step as posible, and
try to implement all commutation and routing at higher layers
R1 Access -- Distribution --- Core --- Distribution --- Access R2
So is better to apply in the Distribution all Filtering and Classification is
the Access Layer is not available to perform this work (like having a IP Phone
that can mark the packets sooner) Trust Boundaries
Just my 2 Cents

Subject: confusing QOS question
I really frustrated with this QOS problem.
Assume company that run VOIP connected to ISP for accessing to the
internet.
If this company run QOS on its edge router to prioritize voice traffic,
there is no change occur to incoming voice traffic since service provider
not run QOS and company's voice traffic must first come to service provider
routers then come to company's edge router.
Routers implement QOS on their outgoing interface (assume we implement QOS
on edge router interface that forward traffic into company and ISP not run
QOS so traffic come across ISP router without prioritizing and running QOS
on our router not help us)
So if ISP not run QOS on its router , implementing QOS on edge router is
useless and we can't prioritize our traffic without help of ISP.
SO what's the point to implement QOS for this company?
Thanks
