education research legacy

PSC-EXT — the external-facing network of the Pittsburgh Supercomputing Center

(PSC), a high-performance computing and networking center founded in 1986 as a

joint effort of Carnegie Mellon University and the University of Pittsburgh.

What it's used for

  • Connecting PSC's supercomputing systems and their research users to the wider internet.
  • Serving 3ROX, the Three Rivers Optical Exchange — the regional aggregation point PSC operates for research and education sites across western and central Pennsylvania and West Virginia. Members include Carnegie Mellon, Penn State, the University of Pittsburgh, West Virginia University, and WVNet.

Notable

  • Research-and-education address space: about 59,000 addresses supporting scientific computing and a regional REN, not commercial customers.
  • 3ROX carries both commodity internet and research paths, including a 100 Gbps connection to Internet2.
  • Its parent institution Carnegie Mellon holds the single-digit [AS9](https://asn.ipinfo.app/AS9).

Interesting

  • PSC was one of the original five NSF supercomputing centers, the program that seeded NSFNET and, with it, much of the early commodity internet. ARIN registered AS5050 in 1995.
