It is not clear this point is true in a relevant scenario. Before
it is meaningful to talk about QoS in an IP setting you have to
assume RSVP is deployed and working. You have to assume the (CS)routers
understand RSVP, can allocated resources meaningfully, and have
established VCCs to support the desired QoS (and that's a lot of
assumptions already). If the ATM paths in and out of the
CSR are already capable of supporting the RSVP-reserved QoS,
what makes you think jamming the incoming VCC into the outgoing
VCC is going to disrupt this?

cheers,
gja
