PSC and Cisco Researchers Author Extended

PITTSBURGH, October 24, 2007 — Researchers from PSC's Advanced Networking group in collaboration with Cisco Systems have proposed a new Internet standard to help diagnose and resolve network performance problems. The document - "TCP Extended Statistics MIB," by PSC researchers Matt Mathis and John Heffner and Rajiv Raghunarayan of Cisco - describes extended performance statistics for TCP (transmission control protocol), a core software protocol that underlies the majority of Internet applications.

With the performance statistics defined by this document, diagnostic tools can - in situations of poor network performance - directly ask TCP why it is slow and gather information on the nature of the problem.

Penn State connects to national research network

UNIVERSITY PARK, PA, June 29, 2006 — Researchers and scientists at Penn State now have the ability to use virtually unlimited bandwidth to expand methods of data acquisition and collaboration.

The National LambdaRail (NLR) network, now operational at the University, is a national consortium that provides users unprecedented control over its next-generation network infrastructure, offering up to 40 individual fiber “light paths” — each of which can transmit data at 10 gigabits per second. The rapidly expanding NLR infrastructure is the result of over three years of work and nearly $100 million in funding by its member institutions and businesses.

National Lambdarail Launches Transit and Peering Project

Five NLR Members Begin Project to Improve Network Performance and Reduce Costs of Internet Services.

CYPRESS, CALIF., April 20, 2006 — National LambdaRail (NLR), a consortium of leading U.S. research universities and private sector technology companies, today announced that it has inaugurated a project to provision an intelligently managed nationwide peering and transit program. The initial participants include NLR members: the Corporation for Education Network Initiatives in California (CENIC), Front Range GigaPoP (FRGP), Mid-Atlantic Terascale Partnership (MATP), Pacific Northwest Gigapop (PNWGP) and Pittsburgh Supercomputing Center (PSC).
