Its about the same speed. I was fortunate enough to able to run some tests a while back on both Juniper and Cisco gear to seek the truth in MPLS's speed. -----Original Message----- From: alok [mailto:alok.dube@apara.com] Sent: Tuesday, November 26, 2002 2:12 AM To: asimha@cisco.com; sthaug@nethelp.no Cc: rogerw@nordlink.com; mpls-ops@mplsrc.com Subject: Re: Fwd: [MPLS-OPS]: basic question on MPLS 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... -rgds Alok ----- Original Message ----- From: <sthaug@nethelp.no> To: <asimha@cisco.com> Cc: <rogerw@nordlink.com>; <mpls-ops@mplsrc.com> Sent: Tuesday, November 26, 2002 3:12 PM Subject: Re: Fwd: [MPLS-OPS]: basic question on MPLS > > At least it is not noticeably faster :) And of course > > imposition/disposition is in fact slower than plain IP.
