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

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
