Help with conceptual question on MPLS vs. ATM

Answered Question
May 15th, 2009

A network event speaker mentioned that she sees MPLS can be a "replacement to ATM" technology.

Does that make sense?

I know how MPLS can be used, but so far I haven't seen that related to replacement of ATM.

If the statement makes sense can elaborate? Thanks.

I have this problem too.

1. Yes

2. One could consider ATM a precursor to MPLS in that you can direct traffic via VPI/VCI. This is essentially layer 2 Psueudowires. Its a somewhat dated approach.

MPLS Provides similar functionality at Layer 3 with a few more features.
