The goal of the Performance Initiative is to create a predictable, and well-supported environment in which Internet2 campus network users have routinely successful experiences in their development and use of advanced Internet applications by focusing resources and efforts on improving performance problem detection and resolution throughout campus, regional, and national networking infrastructures.

Carla Hunt, MCNC's Manager of Knowledge and Information Systems and co-chair of Internet2's Performance Working Group, talks about the importance of collaboration to help solve network performance challenges. Recorded at Winter 2011 ESCC/Internet2 Joint Techs, Clemson University, Clemson, South Carolina.
Monitoring and Measurement ProjectsThe Performance Initiative is actively involved in a variety of projects, many of which are linked to the international perfSONAR effort:
- perfSONAR-PS – an implementation of the perfSONAR network performance measurement framework.
- OWAMP – a tool developed as a sample implementation of IETF RFC 4645 to measure latency; this has been used on Internet2 networks for several years and is in active use by the LHC community.
- BWCTL – a tool developed to schedule authorized bandwidth tests in a non-conflicting manner; currently using Iperf to conduct the tests, BWCTL prevents tests to and from a given location from interfering with one another.
- NDT – a user-friendly tool to identify certain known problems and to provide data on performance problems that can be emailed to technical support staff, giving them a 'snapshot' of the problem as it occurred.
- pS-Performance Toolkit – a customized version of a Knoppix Live-CD bootable disk; this product offers a complete network performance suite pre-installed (and, in many cases, pre-configured) that is ready to be dropped directly into a network operations center (NOC) of any size. With the integration of perfSONAR tools, the results of both passive and active measurements can be shared in a federated environment with your peers enabling the early detection of performance issues.
- Internet2 Network Observatory Data – data collected at the 11-Internet2 Network router nodes (OWAMP, BWCTL, and other tools) is provided to the community via the Internet2 Observatory.
Performance Enhancement Projects
- Phoebus – A session-layer approach to increasing performance, Phoebus allows users to identify the required parameters for data transfer (latency, loss, speed, etc.) to optimize their application's use of the network.
- Dynamic Circuits – This project is working with the Performance Initiative to identify and apply tools and techniques to provide users with the information they require when setting up, using, and dismantling dynamic circuits.
Outreach and Training
- Network Performance Workshops (NPWs) – one of the Internet2 hands-on workshops, the NPWs use the pS-NPToolkit and other open-source performance and monitoring tools during this 1.5-day hands-on workshop to lead participants through using a variety of tools to solve commonly occuring but troublesome issues, where straightforward trouble-shooting often fails.
- Jumbo Frames Equipment Testing – This page lists gigabit networking gear tested to identify gear that IS jumbo frame (MTU>=9000 bytes) clean, and gear that is NOT jumbo frame clean.
- ESnet's TCP tuning site is highly recommended for information on bulk data transfers over WANs: fasterdata.es.net
