With the national digital economy strategy to accelerate the implementation of construction, computing infrastructure has become an important engine for the development of the digital economy. The new generation network technology has changed from information data communication to intelligent processing of information data, and the integration of ubiquitous computing, storage and transmission resources has gradually formed the computing networking. As a new type of network architecture first proposed by my country, computing networking is an important basis for promoting the development of my country's information industry and supporting the development strategy of“network strengthening and digital China”in our country's“14th Five-Year Plan”development plan. In this context, computing networking is proposed to build the deep integration of network system and computing system. On the one hand, it improves network service quality, resource scheduling, and service function orchestration capabilities through computing, and realizes intelligent and efficient network computing services; on the other hand, convergence realizes cloud-centric computing resource operation, and uses the network to promote efficient scheduling of computing. However, the research on computing networking is still in its infancy, and no consensus has been reached on architecture, standards, and technologies. The design of relevant architecture and standards relies on traditional network technology, and there is a lack of building a unified computing networking standard system. The research faces many new needs and new challenges, such as“where to compute”,“what to compute” and“how to compute”. In this paper, based on the previous works of identifier networking and smart identifier networking, we propose a novel network architecture with its associated key mechanisms, namely computing integration networking (CIN) in view of the two inevitable trends of deep integration of heterogeneous networks and intelligent network innovation. By multi-network fusion networking and high-efficiency compatibility, multi-dimensional unified identification and intelligent analysis and mapping, on-demand networking and computing-network collaborative transmission, collaborative computing and optimization of computing-network integration, CIN constructs a new network system theory with deep integration of computing networking. It aims to provide diversified computing services for different industries and users on demand. CIN breaks through the development perspective of network private network, combines the development trend of network integration and intelligence, researches and builds a new theoretical system and construction, breaks through key core technologies, and realizes core technologies that are independently controllable and compatible to replace existing networks and functions. The original construction goal of leading international performance meets the major strategic needs of the country and the industry, promotes the development of the national digital economy, and lays a theoretical foundation for the overall layout of the national integrated computing. © 2022 Chinese Institute of Electronics.
