    • Mechanism, problems and countermeasures to stimulate the value of data
    • HE Wei
    • Information and Communications Technology and Policy. 2020, 46(6): 4-7.
    • Abstract ( 314 )   
    • Data is of great importance to the digital economy and economic society. Increasing the value of social data resources has become an important strategic deployment of the country. To fully stimulate the value of data elements, it needs to go through three stages, resource-based improvement of data quality, asset-based release of data value, and capitalization of expanded data value. In this process, challenges such as difficulty in resourceization, low degree of capitalization, and great obstacles to capitalization still exist. Taking multiple measures to solve problems in a targeted manner and accelerating the market-oriented configuration of data elements is necessary.

    • Abstract ( 265 )   
    • Starting from the key parameters of data center power utilization efficiency (PUE), this paper analyzes all aspects of data center energy efficiency, including infrastructure server, network and reliability, and points out that these key parameters can be used for the overall comprehensive evaluation of data center, so that the design and evaluation of data center infrastructure has a quantifiable basis. Aimed at parameter optimization, this paper studies the supervised learning algorithm, unsupervised learning algorithm and reinforcement learning method, and points out that the most distinctive feature of machine learning is that there are many algorithms, different ideas and different development paths. Then, based on various learning algorithms, this paper analyzes and designs the data center parameters automatically from the aspects of operation and maintenance parameters optimization, PUE optimization and so on. Finally, the combination of machine learning and edge computing in the future is analyzed and introduced. It is believed that machine learning algorithm will have better use scenarios in the new field of data center, and can bring along greater benefits.

    • Information and Communications Technology and Policy. 2020, 46(6): 30-35.
    • Abstract ( 445 )   
    • Requirements such as virtualization, automation, flexibility and scalability are given out by cloud data center network. SDN technology meets these requirements well with its features of separation of control and forwarding,centralization control, capability of open network, etc. SDN is widely adopted in cloud data center network recently.Resources such as virtual machines, bare -metal servers and dockers are provided in cloud data center. In order to manage the whole network for all these resources, SDN can be classified into three categories including hardware scheme, software scheme and hybrid scheme. This paper gives out research and analysis on three schemes and then makes suggestions on how to use SDN in the real cloud data center network.

    • The application of a new supply chain management based on the identity resolution for small and medium-sized enterprises
    • FEI Haiping, LIN Ronglai
    • Information and Communications Technology and Policy. 2020, 46(6): 55-61.
    • Abstract ( 264 )   
    • At present, the management model of the supply chain is more and more difficult to meet requirements of small and medium-sized enterprises. Its long whip effect, low level of coordination, and multi-source heterogeneous data hinder the cooperation between enterprises. With the rapid development of identity resolution, it can reorganize and optimize the supply chain management mode and overcome the defects in the supply chain management when applied to the supply chain management system. This paper proposes a supply chain platform based on identity resolution. When applied to the new ultra-fiber material industry, the platform can ensure timely response to customer needs, improve the level of collaboration between enterprises, and improve the coordination of the whole industry chain. Meanwhile, it can achieve mutual benefit for the upstream and downstream firms in the supply chain. Finally, social resources can be maximumly utilized

    • The construction and evolution of international soft law based on the process of global cyberspace stability
    • GUO Feng, LIN Zihan, HU Zhengkun
    • Information and Communications Technology and Policy. 2020, 46(6): 62-66.
    • Abstract ( 182 )   
    • In 2016, The Hague Center for Strategic Studies (HCSS) and the East-West Institute (EWI) issued an initiative to form the Global Commission on The Stability of Cyberspace ( GCSC ), and then announced the establishment of GCSC at the Security Conference in Munich in February 2017. Since established, GCSC has put forward 4 Principles, 6 recommendations and 8 norms of cyberspace stability which lead the formulation of global cyberspace stability rules. Although GCSC emphasizes the multi-stakeholder model to promote the formulation of cyberspace stability rules, it is mainly driven by Western powers. And now, the proposed rules are less practical, but their influence will continue to rise in the future. China should continue to closely follow the development of GCSC,participating and influencing the process of GCSC.
