Open Flow is a standard protocol for differentiating forward function and control functions to facilitate the management of big network of SDN. The research have been carried out before using the emulator SDN Mininet. However Mininet has many shortcomings, such as the performance of which is less than the maximum due to simulation. Then some researchers also use the Net-FPGA as device. This device is less suitable for small scale because the prices are quite expensive and programming is quite complicated. In this study, SDN implementation carried out using OpenvSwitch as forwarding function mounted on TP-Link that has modificated using openwrt as firmware and Raspberry Pi with Ryu SDN Controller as control functions. The result shows that routing static can be implemented on SDN Network which use Raspberry Pi with Ryu Controller as control function with average bandwith 536.0909 Mbits/sec and average uptime network is 10.45 second.

The operation control of the micro-grid system is the foundation to protect micro-grid equipment, to realize associate control and optimize economic operation. Looking on Chenjiazhen micro-grid in Shanghai as model, the paper set three hierarchical controls: protection control, micro-grid coordinated controller control which can achieve millisecond time precision and intelligent community energy management system control. Different level control function has been divided. Control functions in all levels complement each other and collaborate together to achieve the coordination and control of micro-grid running.

The Impact

In recent years, some cities have experienced significant growth in terms of command and control functions of cities, and thus have managed to relocate themselves to a much upscale position in the global economy. The main goal of this study is to examine the command-and-control function of cities and the impact of the relocation of corporate headquarters on a city’s command-and-control function. The study examines the changes in the revenues of companies located in selected cities and countries and measure the command-and-control function (“C&C”) of cities that well illustrates the strength of cities and countries in the global economy. To achieve our goals, we employ a composite indicator, the Command and Control Index that integrates such fundamental financial data of companies as revenues, profits, market value, and assets. In the analysis, we consider the companies that are listed by Forbes Global 2000. Our findings reinforce that the command-and-control function of the traditional centers of corporate headquarters has been lessening for a while, whereas cities located in developing countries and China in the first place have been occupying an increasing position in the global command and control. Now, we are experiencing the robust growth of Beijing’s command-and-control function index, and the decline of that index of the former leaders (i.e., New York, London, and Tokyo). We can also draw the conclusion that the migration of headquarters does not significantly impact the change of cities’ command-and-control function. In addition, when relocating the headquarters, most companies have remained within the same country and some of them have not even left the metropolitan area itself. In recent years, the number of those companies that have relocated the corporate headquarters has increased, and they have experienced increase in their revenues as well. To attract more corporate headquarters, cities has to offer an attractive environment for companies which strategy should be supported by such governmental initiatives as the reduction of corporate taxes for relocated companies.

Control Implementation

The paper examines current aspects of the tax control policy ensuring timely and full budget gains during the transition to the digital economy. The subject of the research is managerial and tax relations under the economy digitalization conditions. The objectives of the research are the definition of targets for improving the efficiency of the service and control functions of tax authorities and determining the specifics of choosing indicators for the digitalization of the economy. The paper analyzes the efficiency of tax authorities by two criteria: the quality of providing the state services and the quality of the tax control implementation. It is concluded that the transformation of the activities of tax authorities in the digital economy with a shift from the exclusively control function tawards the emphasis on the service function requires a change in the tax employees motivation system and a higher degree of automation of their work.
