The Hong Kong Academic and Research NETwork (HARNET) is the wide area network which links up the campus networks of the eight tertiary institutions in Hong Kong and connects them to the global Internet. HARNET is operated and managed by the JUCC to promote the development, deployment, operation and technology transfer of advanced network infrastructure for innovation, research and educational excellence in Hong Kong.

The HARNET backbone is a Metro Ethernet based solution with dual HARNET data centres located at The University of Hong Kong (HKU) and The Chinese University of Hong Kong (CUHK).
