The Trans-Eurasia Information Network (TEIN) initiative was launched at the Asia Europe Meeting (ASEM) Summit in Seoul in 2000 to improve Euro-Asian research networking. The first result was the installation of a France-Korea connection (TEIN1) in 2001 which was upgraded several times in the following years to meet the increasing demand from users. ASEM 6 in Helsinki in September, 2006 marked the official inauguration of TEIN2, which extended the bilateral success of TEIN1 to the regional level by creating the first large-scale regional data-communications network for research and education across the Asia-Pacific region.
TEIN2 had the following three principal objectives:
Under TEIN2, National Research and Education Network (NREN) in 11 Asia-Pacific countries were connected to European research network GEANT. European Commission was partly funding the connectivity between Europe and Asia. TEIN3 that started in 2009 spanning over 2 years, expanded its footprint to South Asia bringing the total number of partners to 18. Australia, China, Indonesia, Japan, Korea, Laos, Malaysia, Philippines, Singapore, Thailand and Vietnam were the partner countries in TEIN2. Now in TEIN3, Asian countries, namely, Bangladesh, Bhutan, Cambodia, India, Nepal, Pakistan and Sri Lanka are also being connected.
TEIN3 Point of Presence (PoP) has been co-located at ERNET PoP at Mumbai and is acting as the hub for connecting research networks in South Asia except Pakistan. From Mumbai, two high speed links of 2.5 Gbps each have been commissioned to Europe and Singapore providing direct connectivity to GEANT and TEIN3 PoP at Singapore. India is now acting as the hub for connectivity between Europe and Asia-Pacific countries. European Union is partly funding the connectivity under TEIN3. The network of ERNET India is connected to TEIN3 PoP in Mumbai.
