The Advanced Networking group at Pittsburgh Supercomputing Center conducts research on network performance and analysis in support of high-performance computing applications. They also develop software to support heterogeneous distributed supercomputing applications and to implement high-speed interfaces to archival and mass storage systems.
Work done by the Advanced Networking group includes TCP implementations, TCP tuning, and software to monitor and improve network performance.
3ROX – The Three Rivers Optical Exchange (3ROX) is a regional network aggregation point, also called a GigaPoP, providing high speed commodity and research network access to sites in western and central Pennsylvania and West Virginia.
Web10G – Web10G promises innovations in performance, stability, optimization, and network diagnostics to anyone who wants to fully exploit modern high bandwidth connections. It provides users with have real-time statistics about their network connections, and allows them to fine-tune some characteristics of the connection to improve performance.

KINBER and PennREN – The Keystone Initiative for Network Based Education and Research (KINBER) serves as coordinator for the construction and management of a Pennsylvania-wide fiber optic network, PennREN (Pennsylvania Research and Education Network). PennREN will be accessible to educational, research, health care, and economic development partners seeking to aggregate services for their members and subscribers at affordable cost.
