JGN2 Linking multiple facilities “in-line” DDoS attack/traceback simulation Attacker emulation SIOS Vulnerability NiCT Koganei Intermediate network emulation StarBED Internet Simulator (Large Reconfigurable PC Cluster) Victim emulation NiCT Kobe Suggesting: Expanding capacity of facilities. Creation of new facilities. “Source – process – sink” structure in networked *Science.
Importance of testbed activities Different area of science has different properties and requirements. How (and how much, how fast) data is produced and consumed. Delay & jitter tolerance, buffering behaviors. Instrumentation interfaces. Many of these properties and requirements usually surface only through actual experiments. (Even for concerning scientists!) Area (even application) specific analysis and trouble shooting methods. Support mechanisms.
Global collaboration structure of network infrastructure and sciences *Science is essentially “International”: Focus on International collaboration of various activities. Global *Infrastructure as “catalyst” to accelerate international *Science activities. Mutual benefit between *Science and *Infrastructure: Accumulation of experiences. Feedback into global infrastructure control/data plane design.
