hi,

One of the initial proposed advantages of MPLS(tag switching at that time) 
was that label switching can be done faster than IP forwarding/switching. 
Its now said that with the kind of routers we have today this difference
is negligible. More so in the case of routers with hardware assisted 
forwarding. Has there been any tests (on different vendors' routers)
which conclusively shows that the difference is really negligible even
for amount of traffic handled by Internet core routers today ?

cheers,
Santhosh.
