There is nothing inherent in Ethernet which precludes shaping.  Low- and
mid-range routers can do it just fine.  If your core router doesn't, speak with
your vendor.  Then again, do your core routers really support shaping on OC192
FR either?

If those boxes approached the reliability of carrier FR/ATM gear, that might be
relevant.
