Hi,

I guess it will be faster on the P router......

mainly coz now you dont switch on "destn IP " lookups on ur Forwarding Table
(FT), u switch on labels...

and labels are 20 bit not 24 bit..

seperating signalling (routing) from forwarding does help..

its simple, is the router noticeably faster when you have a seperate "FT"?
surely you cant dispute that.....

if yes..now comes features and scalability..RSVP-TE stuff to be done (how
would you do it with only 8 queues in diffserv?)...
and how do you make "VPNs"?

so it has to be looked at not in terms of "raw switching" but "features +
raw switching" being faster...
