The Chinese University of Hong Kong (CUHK) has always been exploring opportunities for cooperation between industry, academia and the research sector. Last month, the Institute of Network Coding (INC) at CUHK signed a collaboration agreement with SI-TECH Information Technology Co., Ltd (SI-TECH), to apply CUHK research works on Network Coding to the core technique of cloud storage of the SI-TECH mobile billing data centre.

The agreement signing ceremony held in CUHK was officiated at by Prof. Walter Ho, Director, Office of Research and Knowledge Transfer Services (ORKTS) at CUHK, Prof. Raymond Yeung, Choh-Ming Li Professor of Information Engineering and Co-Director of the INC at CUHK, and Mr. Foster Wu, the Chairman of the Board of Directors and Chief Executive Officer of SI-TECH, together with other involved personnel.

Through this collaboration, SI-TECH will apply theories and algorithms of Network Coding based Distributed Data Storage (NCDS), developed by Prof. Yeung and his team, to its mobile billing data centre. NCDS is based on the concept of network coding which can improve the capacity and efficiency of data storage by reducing the required storage hardware and the repair time of data storage systems as a whole. This is especially important amid the fast growth of data which is projected for the years ahead.

Prof. Yeung remarked, “This will be an important impact case demonstrating the collaboration between the University and industry. SI-TECH took about a year to develop a billing information storage system. They are very strong in filing systems, but applying coding for storage is INC’s advantage. During the development process, our team complemented them in this aspect. The system is already undergoing a trial run and SI-TECH will use NCDS for in-house use, for other billing operators, and furthermore, for other industries in mainland China.”

The INC has been actively exploring opportunities for technology transfer to technology companies. This is the first collaboration agreement signed with a proven technology company in mainland China. Prof. Ho said, “I am gratified to see another piece of important technology developed at CUHK being transferred to industry. This is in line with our University’s mission, which is to strive to nurture innovation, entrepreneurship and knowledge transfer for the advancement of humanity.”

Mr Wu said this was also of strategic importance to SI-TECH as this was the first collaboration agreement with a tertiary education institution outside mainland China. He believed the technology developed by CUHK would effectively improve the core competence of the company, and the reliability, security and intelligence of its future products in the distributed environment for cloud computing and for the Internet of Things (IoT). Founded in 1995 and listed on the ChiNext of Shenzhen Stock Exchange in 2017, Si-Tech provides integrated information and communications technology (ICT) solutions in cloud, big data and mobile internet to telecommunication companies, government and small and medium businesses.

About the INC

INC was established in 2010 with funding support from the Areas of Excellence Scheme under the Research Grants Council (RGC) of the HKSAR Government and a matching grant from CUHK. It is the world’s first institute which conducts cutting-edge research on the theory of network coding and its various applications in internet communications, wireless communications, information security, and data storage. It aims to further enhance Hong Kong’s leading position in network coding by publishing original research findings and developing advanced technologies based on such findings.
