Wu Jiangxing: Architecture Is the Key to Innovation

On May 15, Wu Jiangxin, Academician at the Chinese Academy of Engineering and Zhejiang Lab Chief Scientist in Cybersecurity, shared his experience of developing program-controlled switches with the research team at Zhejiang Lab. “In 1985, I was given the research task to develop a program-controlled switch. But I was majoring in computer science at that time. Conventionally speaking, if I had begun to study communications from zero, it would have taken me at least ten years to find the solution. However, back at that time, the communication infrastructure in China was so backward that it was common to see people not able to afford phones and make calls. Therefore, it was urgent for us to overcome the technical problems of large program-controlled digital switches, a key technology to communications,” said Academician Wu.

“Facing such an urgent national research task, I locked myself in a room for seven days and nights. Suddenly, an idea popped into my head: why not use my computer expertise to develop a computer that can make phone calls?” Guided by this unconventional research idea, Academician Wu and his team successfully developed the world-leading HJD04 10000-line Program-Controlled Switch in 1991.

Academician Wu, known as “the Father of China’s High-Capacity Program-Controlled Digital Switches”, encouraged the researchers at Zhejiang Lab with his own experience. He said, “We have to get out of our conventional thinking, carry out research from a different perspective, and achieve original innovation from zero to one.”

As the Lab’s Chief Scientist in cybersecurity, Academician Wu expressed his expectations of the team at the Research Center for Industrial Internet. First, the team should work hard to achieve theoretical and technological innovations in order to support China’s efforts to reach a higher position in the global information technology industry. Second, the team should grasp new opportunities brought by the high-quality development of New Infrastructure projects and the integrated innovation of different disciplines, further strengthening studies on endogenous security for related new infrastructure. Third, as Academician Wu has emphasized that the innovation in system architecture is the key to cybersecurity innovation, the team should carry out original innovative research in frontier cybersecurity areas by following the principle that architecture determines performance, security, and application.
