Hello,
 RFC 2474 point 2 states that "A differentiated services boundary can 
be further sub-divided into ingress and egress nodes, where the 
ingress/egress nodes are the downstream/upstream nodes of a boundary 
link in a given traffic direction.".
Query :
At the "ingress" of a DS domain  shown below:

         In __________
  Interface |Ingress  |      DS domain
        ----|Router   |----
        ----|         |---- 
            |_________|Out Interface
            
1)Should Differentiated services compulsorily be applied at the "In 
interface" of the router.
2)Or should it be at the "Out interface " or both
3)What are the possible scenarios for such  cases.

Thanks and Best Regards,
Manoj Alva
