Abstract：At present, domestic terminals are gradually becoming the mainstream of China's terminal market, and terminal products based on the PKS (Phytium+Kylin+Security) system, as the main force in China, undertake a more important mission and urgently need to speed up the optimization to meet the needs of various domestic industries. To meet the growing needs of the user group, this paper predicts user function usage scenarios from the user's point of view on the basis of the single-point verification method of functions, and innovatively proposes a terminal function scenario verification method based on the PKS system. By comparing and analyzing the two methods, the verification data of three domestic terminals proves that the efficiency and value of the functional scenario verification method are better than the traditional single-point verification method, which can promote the continuous optimization of domestic terminals and provide new ideas for the domestic terminal verification system.

Abstract：As a key component for offloading and accelerating key services in cloud data centers, smart NIC is significant for improving the processing efficiency of network and storage services in data centers. The service needs of data centers are complicated, lacking the support of mature commercial chips, and the design of smart NIC is difficult to meet the multiple requirements of service offloading flexibility, high performance, cost economy and so on in a limited space. Designing a separate architecture scheme to physically decouple the smart NIC interface function from the service offload processing function, break through the physical space limit of the network card, reuse the service offload processing hardware resources, and improve the cost economy is an effective way to achieve the engineering and large-scale deployment of smart NIC.

Abstract：With the development of communication technology and the increasing demand for smart campuses, traditional campus networks are also faced with major challenges such as insufficient bandwidth, inflexible networking, and difficulty in accessing the Internet of Things. In recent years, the industry has introduced network technologies such as PON and WDM in the campus network, or improved and optimized the existing Ethernet technology to deal with the problems and challenges. This paper summarizes the representative networking solutions in the industry, analyzes the technical principles, characteristics, and networking technology advantages and disadvantages, and uses the campus network scene as standard to judge and summarize the adaptability respectively, so as to achieve the comparison and judgment of technological advancement. Through the comparison, the shortcomings of the existing technology and the advantages and disadvantages of the new technology can be more deeply understood, in order to be used as a reference for solution selection in the future network construction.

Abstract：In recent years, the localization of computer hardware and software systems has developed rapidly, and the general technical architecture and ecosystem Phytium Kylin Security (PKS) led by China Electronics has become more and more mature. At present, most of the research on the terminal performance scenario verification method is based on non-domestic system equipment, lack of pertinence, and it is difficult to fully explore the problems of domestic computer hardware and software system.

Abstract：As the core basic equipment of the industrial control system, PLC is widely used in important national infrastructure and various industrial control fields. It is the top priority to realize the transformation from made in China to intelligent manufacturing in China to control the industrial site independently, safely, stably and reliably. In this context, domestic PLC has a strong and rapid development momentum, especially in high-end application fields such as aerospace, national defense and military industry. There is an urgent demand for domestic high-performance PLC products. Due to the late development and less application of domestic large-scale PLC, how to evaluate the performance of domestic PLC and whether it can meet the industrial field application is lack of unified standards and evaluation methods. In view of this problem, a set of comprehensive test platform for domestic high-performance PLC is designed. Two mainstream domestic PLCs are selected for quantitative comparison of horizontal parameters with a foreign mainstream product. The key performance indicators and evaluation methods of high-end PLC are proposed. By building a hardware in the loop virtual industrial scene, the ability of PLC to meet the application is tested and compared. The effectiveness of the test platform is verified through a test example, which provides a basis for the evaluation of domestic high-performance PLC Choose to provide reference, promote the normalization, standardization and scale of domestic PLC, and help the high-quality development of Industry 4.0.

Abstract：Applied on machine learning, malicious web page detection technology is studied in this paper. At present, popular methods of “feature code” or “whitelist” can only detect known malicious web pages. The method of machine learning can detect unknown malicious web pages, but it has to face the problem of that the data is large, complex and tedious when processing web page features. In this paper, a Hash compression method is proposed. The method can map 1.5 million features into 20,000 feature space, and train multiple traditional machine learning models and integrated learning models using k-fold cross-validation method for extracted feature data. The best classification detection model will be selected by evaluating the detection effect of the model.

The establishment of the hardware and software ecosystem includes the infrastructure composed of the underlying hardware and operating system, abundant general tool software, a large number of middleware, applications, and a large number of developers. In order to solve the healthy development of independent hardware and software ecology, it is necessary to understand the development of ecology and study its construction mode.

By combining the adaptive product data and developer behavior data, the characteristics and differences of the three construction modes are expounded, providing experience reference and decision support for the successful construction of the independent software and hardware ecosystem in China′s IT industry.

Abstract：Based on the development of China′s Internet and the policy orientation of the country′s new infrastructure, data centers are booming, and data center networks are also transitioning from 10G and 40G networks to 25G and 100G networks. Even some leading companies are already experimenting with 100G and 400G networks. At the same time, with the escalating trade friction between China and the United States, the phenomenon of neck stuck is becoming more and more serious. Whether it is possible to build a cloud data center network based on fully autonomous chips and technology is an important issue. Cloud data center networks usually include SDN controllers, switches, security devices, network offloading devices, virtual switches vSwitch, smart network cards and other related components. The hardware and software of these components need to be domestically independent to get rid of the dependence on foreign technology. This article focuses on the technical characteristics of the autonomous data center, the feasibility of the autonomous layout of related components, and the choice of autonomous methods and solutions.
