MPLS VPNs or not?


  What evidence do you have that:

1) UUnet is/was a success,

2) if it was a success, the determining factor was its use of ATM,
   rather than its first mover advantage, financial/management stucture,
   industry trends, etc. For example, UUnet used ATM because that was
   what the bellheads would sell them. At the time, there was no
   alternative to the bellheads.
