perfSONAR

Purpose: perfSONAR is a network measurement toolkit designed to provide federated path coverage and help establish end-to-end network performance expectations.
Problem diagnosis: It helps engineering teams identify and isolate network performance problems as they happen.
Measurements and visualization: It provides a uniform interface for scheduling measurements, storing data in uniform formats, retrieving data at scale, and generating visualizations.
Measurement coordination: Operators can coordinate tests among multiple nodes using a shared JSON mesh configuration, with results stored on each node or sent to a central dashboard server.
Measurement types: A standard node can run throughput or latency tests on a single network interface, while simultaneous testing on one interface may affect accuracy.
Integrations: The documentation includes deployment guidance for Docker and Ansible, and a cookbook for a central archive with Grafana.
Data access: The documentation provides a perfSONAR Client API and an esmond API reference for accessing raw data.
Deployment limits: The project describes perfSONAR as software installed on a local server controlled by the operator, and its deployment models require maintaining the nodes and test configuration.
Security: The project directs users to its documentation for security considerations and lists firewall and security software configuration guidance in the user guide.
License: perfSONAR components and tools are licensed under the Apache License, Version 2.0, and distributed without warranty as described on the license page.
Support: The project provides a user mailing list for questions about deployments and an announcement mailing list for releases and security updates.
Intended users: The project describes use by science facilities, campuses, laboratories, network providers, exchange points, virtual organizations, network researchers, and software and service developers.
Development: perfSONAR is developed through a partnership that includes ESnet, GÉANT, Indiana University, Internet2, the University of Michigan, and RNP.
