On GSR the lots of intelligence is integrated in linecards. For Sup720
most of the intelligence integrated on the central switching engine. You
can add A and D feature card to the current sup720 linecards that moves
intelligence towards the linecards. One additional missing point in
Sup720: you can't have STM-64 linecard yet. Also some limitation with MPLS
and heavy ACL usage... Some might know more.
