Concluding Remarks (1)

KREONET/KREONet2 - National Science & Research Network by Korean Government

- High-end Application Empowered Network for e-Science/Grid

Toward Global Scale KoreaLight– Multiple International Link based on Lambda Networking over

10Gbps Link with TransLight and GLORIAD

– Leading Role of Lambda Networking Activities in Global Lambda Networking Community with e-Science/ Grid

– KREONet2/SuperSIReN is important flag project for Lambda Grid in Korea


Concluding Remarks (2)Toward Application Empowered Network

– Actively Participate in e-Science and Grid Community– Collaboration with GLORIAD, TransLight, and GLIF/ i-Grid T

eam…

Advanced Network Engineering and Application– IPv6, Multicast, QoS, Traffic Analysis, Security, Lambda etc.
