Hello Dears

am meymoona ahmed , am CCNA work as network engineer in University of Qatar and am MSc student my project is( IP OVER ATM using MPLS ).

According to the e-mails between (Roger Clark Williams <rogerw@nordlink.com>; RickGall1@aol.com and you and Cheers,Andy andAndrew G. Malis <Andy.Malis@vivacenetworks.com> the

MPLS, since it runs over IP, can run happily on a network that is running IP over ATM. The ATM is effectively invisible to the MPLS as it would be to IP. The ATM switches and the ATM pipes between switches are simply open pipes to IP, and therefore to MPLS. This would be called "frame mode over ATM" In this case, the label switch/routers "see" each other through the pipe, labels are exchanged directly between MPLS routers but across the ATM links, routing goes on just as it would with IP. The ATM is simply providing a path that is invisible to IP. I think the better image is a pipe because as a kid I would look through a long pipe under the road .Network design is still an issue, and that depends on your particular needs, how your traffic needs to flow, link capacities and the like.

please  i need to know the methode and mathimatical equation for "frame mode over ATM". Am try to do my research  by simulation please can you help me

 

with my best regards
