The development of this lab series was supported with funding from the National Science Foundation Award 1829698 “CyberTraining CIP: Cyberinfrastructure Expertise on High-throughput Networks for Big Science Data Transfers” at the University of South Carolina (UofSC). The labs provide hands-on training in the technologies used to build and configure high-speed networks.
The High-Speed Networks: Network Tools and Protocols labs are supported using the High-Speed Networks Pod.
