Actually:

3) The best way to manage this situation is to use 
the Class of Service per-VC queuing feature.  This 
will create a separate queue for each PVC, and will 
insure that offending PVCs don't affect other PVCs 
on the same interface.  What it will also do is link

Layer 2 traffic engineering (ATM traffic shaping) to

Layer 3 flow control by using WRED to throttle TCP 
flows on PVCs which are exceeding their ATM PVC 
limits.  As the TCP windows close, the packet flows 
will be reduced until they fit within the shaped 
PVC's limits.

Only one VC queue on the OC12 ATM interfaces on the
GSR series.  So, is it queuing delay or cell loss
slowing it down?
