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.

Requirement
 Probe Server and software
 Iperf
 SCMS (for all to all measurement and
data collection)
 Measurement Server
 SCMS
 MySQL Database
TIEN2 International Link
Discussion
 Most 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
Development
 Better information access
 Data is kept into database now. Better analysis tools ca
be applied.
 Better packaging of the software
 Better probe
 Latency measurement
 Parallel socket management
 Application based network measurement
Area of collaboration
 Probe deployment around Asia
Pacific
 The analysis of the results and
coordinating effort in network
performance optimization
 Development of better
measurement infrastructure
