  1. Building a Network Measurement Infrastructure to Enable E-science Projects in Asia Pacific Putchong Uthayopas, Sugree Phatanapherom, Nopparat Noppakuat, and Maneerat SuriyapiboonwattanaThai National Grid CenterSoftware Industry Promotion Agency(SIPA),Ministry of Information and Communication Technology, Thailand

  2. 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.

  4. Requirement • Probe Server and software • Iperf • SCMS (for all to all measurement and data collection) • Measurement Server • SCMS • MySQL Database

  5. TIEN2 International Link

  6. 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

  7. 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

  8. 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 measurement

  9. Thank you
