Whatever the relative technical merits of MPLS/BGP VPNs over other layer
3 VPNs (GRE, IPsec, L2TP etc) there are many service providers around the world
selling these services. There is clearly a business need for them, and obviously
customers how will buy them (well, we have managed to sell them anyway!), so
there is an economic reason to deploy MPLS.
Layer
2 based LAN extension services will only extend this market further and again
uses MPLS as its base transport mechanism.

Ladies and
Gentlemen:
I have been conducting research
looking for the economic justification for MPLS. I have some feedback,
but sound rationale from the industry has eluded me thus far. I am
looking for a paper, website, etc that explains the benefits of implementing
MPLS (other than technical) or gives some economic modeling for MPLS-based
networks. Any help, reasoning, rationale or personal insights/views
would be greatly appreciated.
Thanks in advance,
Shannon
