I did a lot of work on MPLS and the enterprises last year while I was at
Cisco and got some different conclusions:
Enterprises are not really turned on by full mesh almost all of their stuff
is hub and spoke, even the VOIP.
QOS was not a big thing and it wasn't clear that MPLS added anything hear
for the enterprise users, they do not see any Traffic Engineering services
nor is it offered.
As far as management again to them they do not see any MPLS and have no view
into the provider's network nor have they ever so this was not a big issue
for them.
Most of them were being offered MPLS by their providers but the benefits
seemed to be price only.

Today's focus: Enterprises indicate plans for MPLS VPN use
By Steve Taylor and Joanie Wexler
Early results of a Webtorials survey about WAN service usage
plans conducted in May 2004 and sponsored by Network Physics
turned up some interesting results. In particular, there is a
strong indicator that enterprises are planning fairly broad
adoption of MPLS-based VPN services in the next 18 months.
Some of that growth in MPLS VPN adoption will be at the expense
of traditional frame-relay network services. This is not because
of dissatisfaction with those services but rather it is the
nature of the applications to be supported that seems to be
changing.
Enhanced quality of service (QoS) guarantees, especially for
converged networking applications such as VoIP, plus a greater
degree of meshed networking to support such applications, were
shown to be particularly strong drivers, for example. Businesses
generally don't just build new networks simply because they're
impressed by the idea of QoS or meshed topologies. They build
networks to support the needs of the applications they run.
Clearly, these "network layer" considerations point to the rapid
adoption of converged networking on a widespread basis. But
widespread adoption isn't necessarily a good idea unless the
newly adopted networking capabilities are manageable.
Difficulty with managing MPLS ranks among four of the top six
obstacles to MPLS adoption at the current time. However, the
Webtorials survey results showed that management of the newly
deployed MPLS-based VPN is expected to be at least as good as -
and hopefully better than - current capabilities for legacy
networks. Technically speaking, this is a reasonable
expectation, so one may be quite hopeful that the deployed
capabilities will indeed take advantage of the enhanced
technology.
