The Trans-Eurasia Information Network (TEIN) provides dedicated high-capacity Internet connectivity for research and education communities across Asia-Pacific. With over 50 million users, TEIN is the world's largest research and education network; it currently interconnects universities and research centres in China, India, Indonesia, Japan, Korea, Malaysia, Nepal, Pakistan, thePhilippines, Singapore, Sri Lanka, Thailand, Vietnam, Australia, Bangladesh and most recently Cambodia. It also connects to the 40 million European researchers and academics served by the GÉANT network and supports collaborative programmes with Europe in areas such as Earth observation, climate research, food security, delivery of e-health and e-learning.

Starting with a single circuit between France and Korea in 2001, the TEIN regional network has been managed since 2006 by DANTE, a not-for-profit organisation that operates regional network projects across the globe. In September 2012, responsibility for the new phase, TEIN4, was transferred to the TEIN* Cooperation Center (TEIN*CC), which was established by the Korean government to continue to develop the network up to 2016 with DANTE support. TEIN continues to receive funding support from the European Commission which is contributing €8 million for TEIN4​.​
