The Evolution and Future of the Lanka Educational and Research Network (LEARN)

The Lanka Educational and Research Network (LEARN) was proposed to the University Grants Commission (UGC) to connect universities and research institutions in Sri Lanka. Established in 1990 with LEARNMail, the first email service, it evolved with grants that connected major universities by 1995. Managed by a dedicated committee, LEARN now serves 11 universities with a bandwidth of 2.5 Mbps and offers various services. Future plans include connecting more institutions, implementing e-learning, video conferencing, and expanding bandwidth capacity to enhance educational collaboration nationwide.

  1. Lanka Educational And Research Network Ajantha Atukorale & Nimal Ratnayake

  2. History • The necessity of Academic network that connects all Universities and R&D institutions across the country was proposed to UGC • It was accepted in principle but implementation got delayed due to lack of funds • LEARNMail, the 1st E-mail service in Sri Lanka was started in 1990 • Maintained by group of volunteers

  3. History • CINTEC approved a grant to set up the 1st phase of the LEARN • To connect three universities • University of Colombo • University of Moratuwa • The Open University • Phase 1 completed in 1995 • Three universities connected by 64Kbps leased lines (via SLT)
