Motivation Enabling the successful e-science

projects among collaborators from multiple sites around the world require a good networking infrastructure.

A measurement infrastructure that periodically measures the network performance characteristics is very useful for many reasons Enable a collaborative effort for network

performance tuning possible. S E-science application and tool

developers can use the knowledge learned to adapt the application to these environment.

Data collected and stored can be used for fault modeling, which led to more reliable network setup.

DiscussionMost of the network are being under

utilized. Users and network operators do not even know

it!The coordinating effort in performance

tuning is required.TCP/IP has some serious limitation for long

distance data transfer.Long latency severely degraded the

sustainable bandwidth

DevelopmentBetter information access

Data is kept into database now. Better analysis tools ca be applied.
