I believe the ASR's are very hardware assisted by the route processor. (the control plane is completely isolated). I believe the SIP is what actually handles the forwarding via hardware. Also the fact you can do in-service software upgrades leads me to believe that router has hardware based forwarding as well. Line-rate 10GE with all the ACL's/QoS/MPLS/L2TP/encryption, etc. only in software would be very difficult to do in software without installing a furnace in the rack! ;-) -- Robert Blayzor, BOFH INOC, LLC rblayzor@inoc.net http://www.inoc.net/~rblayzor/
