Abstract
Collaborative HEP research is dependent on good Internet connectivity.
Although most local- and wide-area networks are carefully watched, there
is little monitoring of connections that cross many networks. This paper
describes work in progress at several sites to monitor Internet end-to-end
performance between hundreds of HEP sites worldwide. At each collection
site, ICMP ping packets are automatically sent periodically to sites of
interest. The data is recorded and made available to analysis nodes,
which collect the data from multiple collection sites and provide analysis
and graphing. Future work includes improving the efficiency and accuracy
of ping data collection.
