CRL's Next Generation Internet (hereafter CRL-NGI) project has launched in 1999. Its missions are promoting network science, developing novel NGI transfer protocol, integrating several ongoing Internet testbed projects, suggesting a policy model for NGI to be an authentic information infrastructure, and proposing a unique infrastructure model together with coordinating policies based on the survey of current Internet. We have constructed the NGI with very-high-speed and very-wide-area IPv6 by integrating operation of APII testbeds, AI3 testbeds, Japan Gigabit Network and CRL's other networks. As a result, we found out that local loops in Asian countries were yet immature for the development of Asian Internet and obtained some data that indicated the need to introduce a concept of high-speed network's geographical scalability. Based on these results, as for Asian region, it is suggested that knowledge distribution of IPv6 technology and network optimization are crucial in the future.
