Internet Monitoring in the HEP Community
Warren N. Matthews · 1998
The HEP Internet Monitoring Project (known as PingER) attempts to measure the performance of the Internet used by the High Energy Physics Research community and provide an accurate measurement of the end-to-end performance individuals may expect by monitoring the performance between a given monitoring node and remote node pair. This is achieved by monitoring the packet loss and round trip time (RTT) of ICMP Ping packets from 17 monitoring sites around the world to 373 nodes at 267 sites between 1084 monitoring-host-remote-site pairs, involving 27 countries. This paper details the current work and status of this on-going project. The architecture, methodology and nature of the problem will be reviewed, some trends will be discussed, and the direction of further work will be outlined.
