End-to-End Networking Services
Supporting a user community scattered across the country and around the world, the NAS Networks Group strives to ensure that you, our users, have a reliable, high-speed connection to HECC resources. Our network experts can work closely with you to optimize end-to-end flows, select the most efficient transfer methods and protocols, and fine-tune your systems.
We can also collaborate with remote network teams and system administrators to identify and remove bottlenecks along the network path and improve the throughput of your flows.
Basic Services
The following end-to-end networking services are available at no charge to you.
- Basic and detailed performance analysis and optimization:
- Identify the most efficient file transfer methods and protocols to fit your data transfer requirements
- Monitor data transfer flows to identify and reach out to sites with lower performing flows
- Tune end host TCP stacks to optimize throughput
- Collaboration with your local networking teams to identify bottlenecks and improve flow throughput, including working with:
- Remote network teams and system administrators
- NASA’s Communication Services Office (CSO)
- Wide-area network (WAN) service providers
- Training, troubleshooting, and tool development:
- Provide links and training for available diagnostic tools
- One-on-one troubleshooting assistance to help users identify and address network bottlenecks
- Advise on best practices for data transfer
To request help with these basic services, please contact the NAS Control Room: (800) 331-8737, (650) 604-4444, support@nas.nasa.gov.
Additional Services
Our network experts also help other NASA centers and government organizations design and implement cutting-edge technologies and network security. Such services require external funding based on the required level of effort. Examples include:
- Procure and deploy high availability network environments for critical servers
- Develop unique environments to meet mission/project needs, such as a re-exporter environment to enable remote users to more easily access shared data

Record of Success
Our engineers proactively monitor network performance and often identify issues before they are reported. For example, they detected suboptimal transfer speeds from NASA Johnson Space Center’s (JSC) AeroLab across a 2x1-gigabit per second (Gbps) Ethernet link. Along with upgrading the hardware to a 10 Gbps link, our network engineers actively worked with their JSC counterparts to tune TCP window sizes and network stacks, resulting in an increase in throughput speeds from 125 Mbps to 1.5 Gbps–a 12x improvement.
