Hmmm.... I wonder where I got that idea from? ;-) Maybe your shouting at me
in the middle of Prague street around midnight, while Craig waving an
OpenFlow spec at me, had something to do with it.... ;-)

Yes. MPLS is one of the vehicles interconnecting large user groups.All
applications want to do is to make a use of the "resource" to transport
data. Further, the applications do not care about the internal network
operation, such as routing, load balancing etc. They just want a pipe!
