ESnet Fasterdata Knowledge Base
An Expert Guide for End-to-End Performance Tuning, Tools and Techniques
Network performance problems frustrate scientists and network operators alike. Performance problems can be caused by several factors - including network infrastructure, host configurations, and data transfer applications. Scientists who encounter network problems sometimes resort to antiquated methods of data transfer (for example, shipping hard drives) and scientific productivity suffers as a result.
For over 25 years, ESnet has operated an advanced research network with the goal of enabling the highest levels of performance for the Department of Energy (DOE) scientific community. During this time, our engineers have identified a common set of issues that hinder performance.
To make better use of its accumulated knowledge, ESnet has developed this Fasterdata Knowledge Base. The knowledge base provides proven, operationally-sound methods for troubleshooting and solving performance issues. Our solutions fall into five categories:
- Network Architecture, including the Science DMZ model
- Host Tuning
- Network Tuning
- Data Transfer Tools
- Network Performance Testing
