Abstract
The vision of science grids allocating resources to analyze
huge quantities of HENP data clearly depends on reliable
network performance. Tools developed at SLAC in
conjunction with the Internet2 PIPES project will help to
ensure this. In this talk, these tools will be discussed and
the procedure for publishing performance data, in particular
using the Globus toolkit's MDS and web services will be
reviewed. The subsequent analysis and trouble-shooting
methodology will be discussed with real world examples
from the particle physics data grid (PPDG) and the
European data grid (EDG).
