Title: PingER: Internet performance monitoring -- How do collisions make better physics

Abstract

Internet connectivity is critical infrastructure for modern high energy nuclear and particle physics experiments at laboratories around the world. Achieving the ambitious computing goals is dependent on reliable and fast connections between collaborators in geographically separate regions. The ambitious computing goals of experiments such as BaBar, RHIC and the LHC place internet connectivity in a highly critical position. More over the ability to monitor performance and identify weak points for upgrades has become pivotal to recruiting collaborators not only overseas from the location of the experiment but in locations previously considered remote. The methodology of the Internet End-to-End Performance Monitoring (IEPM) project and long-term trends in regional and trans-oceanic performance measured by the PingER tools has previously been described. The project has grown significantly and now 593 nodes at 424 sites in 72 countries are monitored by 28 monitoring sites in 15 countries. A total of 2,138 end-to-end pairs are monitored, making PingER probably the largest performance monitoring project in the world. Recently particular effort has been made to extend the monitoring of locations in East Europe and the former USSR and to Central and South America and the Middle East, reflecting the increasing reach of high energy nuclear andmore » particle physics research.« less
