Who can use the vBNS?
The vBNS was designed for the scientific and research communities and originally provided high speed interconnection among NSF supercomputing centers and connection to NSF-specified Network Access Points. Today the vBNS connects two NSF supercomputing centers and research institutions that are selected under the NSF’s high performance connections program. The vBNS is only available for meritorious research projects with high bandwidth uses and is not used for general Internet traffic.
