perfSONAR: On-board Diagnostics for Big Data

Big science data necessitates the requirement to incorporate state-of-the-art technologies and processes into science workflows. When transferring “big data”, the network infrastructure connects sites for storage, analysis and data transfer. A component that is often overlooked within the network is a robust measurement and testing infrastructure that verifies all network components are functioning correctly. Many researchers at various sites use perfSONAR, a network performance measurement toolkit to isolate many types of network problems that reduce performance. perfSONAR is an essential tool that ensures scientists can rely on networks to get their data from end-to-end as quickly as possible.
