Performance Tools

overview

These software tools—developed with the support of Internet2 members—enhance the deployment and usefulness of high-performance networks. Forged in the context of Internet2’s systems approach to networking and a commitment to open standards, these open-source tools provide capabilities that help realize the potential of existing network infrastructure, and make implementing new enterprise-wide services easier and more effective.

For additional information about these tools, please contact tools@internet2.edu. Also make sure to visit the Performance Initiative page, and consider collaborating in the Performance Working Group.

 

perfSONAR

perfSONAR is a network measurement toolkit designed to provide federated coverage of paths, help establish end-to-end performance expectations and serve as an ad-hoc troubleshooting tool.

One-Way Ping (OWAMP)

OWAMP is a command-line client application and a policy daemon used to determine one-way latencies between hosts.

OWAMP

OWAMP is a command line client application and a policy daemon used to determine one way latencies between hosts. It is an implementation of the OWAMP protocol as defined by http://www.rfc-editor.org/rfc/rfc4656.txt.

With roundtrip-based measurements, it is hard to isolate the direction in which congestion is experienced. One-way measurements solve this problem and make the direction of congestion immediately apparent. Since traffic can be asymmetric at many sites that are primarily producers or consumers of data, this allows for more informative measurements. One-way measurements allow the user to better isolate the effects of specific parts of a network on the treatment of traffic.

The pS-Performance Toolkit contains the latest version of OWAMP. The daemon is started by default with a wide open authentication and resource protection scheme. It is recommended that the deploying party review this to ensure it matches local security policies.
