The purpose of the IEPM-BW project is to develop and use and deploy an infrastructure to make active end-to-end application and end network data transfers and network performance measurements for high performance network links such as are used worldwide by Grid applications and other academic and research (A&R) applications deployed over high performance network such as ESnet, Internet2 and other Academic and Research (A&R) networks in the developed world.

- Provides complementary low impact , overview and more intense , detailed (although short) detailed perfomance measurements:
- The low impact provides network performance measurements to most of the Internet connected world providing delays, loss and connectivity information over long (many years) time periods.
- The higher impact measurements are oriented to high performance links (e.g. grid sites, ESnet and Internet 2 connected sites) and provide Network AND application high throughput performance measurements allowing comparisons, identification of bottlenecks etc.
- Uses both passive and active measurements
- Continuous, robust, measurement, analysis and web based reporting of results and data available world wide.
- Simple infrastructure enabling rapid deployment, locating within an application host, and local site management to avoid security issues
- Provide simple forecasting for applications and for optimizing the frequency of measurements.
...
- Develop/deploy a simple, robust, administratively ssh based active end-to-end application and network measurement and management infrastructure.
- Install/integrate a base set of measurement tools into the infrastructure make regular measurements and record the results. These tools currently include: ping, traceroute, iperf, thrulay, OWAMP, pipechar pathchirp, bbcp and bbftp. pathload
- Develop data reduction, analysis, reporting, forecasting and archiving tools.
- Compare and validate the various tools and determine the regions of applicability.
- Install new network (e.g. the INCITE tools, pathrate and pathload) and application (e.g. GridFTP) tools into the infrastructure, and use it to evaluate the performance of the tools and their relevancy.
Evaluate new TCP stacks such as HTCP, High Speed TCP, and FAST and compare with the default stacks. - Provide access to the data for research, forecasting, validation etc.
