  11. APAN(1998) • NSF required the transit services over TransPAC link. • The owners of point-to-point links started the collaborated operations. • AP Regional networks were developed with a hub in Tokyo. • The institutions with advanced research projects are allowed to use TransPAC link. 2003 Busan AP*Retreat Meeting
