Hands-on Workshop on Science DMZs and Networking for All
Monday, September 18 - 1:00 PM - 4:30 PM
Minneapolis, MN
- University of South Carolina
- Minority Serving Cyberinfrastructure Consortium (MSCC)
- Internet2
Overview
This workshop provides Information Technology (IT) professionals with an introduction to tools and techniques for the monitoring of high-throughput networks and science demilitarized zones (Science DMZs). Each attendee will have full control of equipment pods emulating internetworks and tools to learn and test perfSONAR nodes distributed across networks.
Outcomes
By the end of this tutorial, attendees will:
perfSONAR:
- Describe the operation of perfSONAR and use perfSONAR GUI to configure regular tests
- Use pScheduler’s CLI to schedule tests
- Visualize measurement data using MaDDash
Network Tools and Protocols:
- Use tools and techniques for measuring performance
- Measure the performance of TCP on high-throughput (10 Gbps) high-latency (varying parameters) networks
- Measure the impact of packet loss on throughput
Intended Audience
The tutorial is targeted to IT educators and professionals such as system administrators, network engineers, practitioners. The content is suitable for instructors who want to incorporate advanced material into their networking classes. The content is available for NETLAB systems.
Pre-requisites
The laboratory environment consists of routers, switches, and hosts deployed in IPv4 networks. Attendees are expected to know basic networking (IPv4, local area networks, OSI model). Training activities will be conducted using NetLab. Attendees will be provided with a username and a password.
