Fast Packet Classification for V2X Services in 5G Networks
박우길 한국통신학회 2017 Journal of communications and networks Vol.19 No.3
Vehicle-to-everything (V2X) is one of the key applications of upcoming 5G systems. The 5G systems are highly anticipated to adopt software defined network/network function virtualization technology in their core networks as it provides high flexibility and maintainability. However, if the flow tables in switches, called OpenFlow switches, overflow due to excessive policy rules, the networks suffer from large packet delay and frequent packet drops, and fail to support V2X services. To resolve this issue, we propose a new packet classification algorithm that runs fast even with the huge number of policy rules. There is the minimal concern for the overflow in our scheme since it is a pure software-based approach. Furthermore, simulation results show that our algorithm enjoys both the fast packet classification speed and the short policy update time. Thus, our scheme is very suitable for highly dynamic environments like 5G networks.

The purpose of this study is to explore the roles of diasporas in the development of Asia’s capitalism through the lens of compatriotic Asianization. To do this, it explains how China and South Korea economically mobilized their overseas compatriots in a period of globalization. The study identifies three key roles that the respective diasporas have played in China and Korea’s economic development. First, the diaspora served as investors. This trait was prominent in the Chinese setting. Second, the diaspora served as a source of labor. This role has been particularly salient in South Korea. Third, the diaspora served as overseas customer and middleman. This was evident in both China and South Korea. The diasporas were integrated into the capitalist systems of both their ethnic homeland and their country of residence. Compatriotic Asianization thus appears to be a greater part of economic integration in Asian countries than previously recognized.
