Future Internet architecture: research status, hot topics, and development practice

With continuous increase in the number of its users and applications, the Internet has been gradually encountering the issues of security, mobility, scalability. Therefore, many organizations around the world are engaged in research that aims to overcome these drawbacks. We first describe the main problems faced by the Internet, review some related research, and analyze some promising technologies, such as SDN, NFV, NS, and ICN. Then, we highlight the research work on SINET, which allows to integrate a variety of advanced network technologies and adapt to different application environments dynamically. This design conforms to the development trend of the future Internet.
