PIs: Les Cottrell SLAC
High-Performance Network Research- SciDAC/Base
PingER novel ideas
Low impact network performance measurements to most of the Internet connected world providing delays, loss and connectivity information over long time periods
Network AND application high throughput performance measurements allowing comparisons, identification of bottlenecks
Continuous, robust, measurement, analysis and web based reporting of results available world wide
Simple infrastructure enabling rapid deployment, locating within an application host, and local site management to avoid security issues
PingER: Active End-to-end performance monitoring for the Research and Education communities
Tasks:
-develop/deploy simple, robust ssh based active end-to-end measurement and management infrastructure
-develop analysis/reporting tools
-integrate new application and network measurement tools into the infrastructure
-compare & validate various tools, and determine regions of applicability

Impact and Connections
IMPACT:
increase network and Grid application bulk throughput over high delay, bandwidth networks (like DOE’s ESnet)
provide trouble shooting information for networkers and users by identifying the onset and magnitude of performance changes, and whether they appear in the application or the network
provide network performance data base, analysis and navigateable reports from active monitoring
