The explosive increase in the range of Internet usage gradually makes the speed and capacity of network high-speed, rapidly evolving it into mass storage. Accordingly, network equipment such as switch and router are coping with it through hardware-based rapid technological evolution, but as the technological development of the most basic and essential network security system in the hyper-connected society requires frequent alterations and updates about the security issues and signatures of tens of thousands, so it is not easy to overcome the technical limitations based on the software. In this paper, to improve problems in installing and operating such anti-DDoS devices, we propose a Hi-DPI algorithm best reflecting the hardware characteristics and parallel processing characteristics of FPGA (Field Programmable Gate Array), and would verify the practicality.

In devising technological innovation strategies and implementing successful technological innovation, some of the most important factors may be to determine whether to protect technological innovation and to choose how to protect it. Traditionally, technological innovation has been emphasized to obtain compensation as much as possible for innovation in terms of economics and strategy. However, it can be regarded as a very complicated problem to determine such a protection and its level. Generally speaking, enterprises have some common mechanisms to secure compensation for technological innovation, which are known to be patents, secrecy and lead time advantage. From the standpoint of enterprises, it is very important what strategies should be devised to secure profits for technological innovation. According to some domestic and oversea research results revealed that specific patents are not the best way to Appropriability for technological innovation, while also implying that there exist several different kinds of mechanisms to Appropriability for technological innovation in each industry. Nevertheless, since it shouldn't be ignored that most of the researches have overlooked the characteristics of Korean enterprises and industrial differences, this study intends to clarify the effectiveness of technological innovation Appropriability mechanisms reflecting actual circumstances and industrial characteristics in Korea while classifying them. Also The questionnaires and delphi method used in this study.
