With the development of the mobile Internet, many new Internet traffic features such as variety and randomness are emerging. Thus, the analysis of traffic matrix (TM) plays a significant role in the area of Internet engineering and applications. This project will study the theory of traffic matrix modeling, TM estimation methods, various information extraction techniques and its applications for mobile Internet. Specifically, it includes the following: the new models for mobile Internet traffic matrix, the new TM estimation and restoration methods under the environment with insufficient or missed information, the new methods of analyzing the intrinsic structure of TM, the new information extraction.technologies and the application methods of the TM, the relationship of TM high-variability in time or geography with serious social events and the forecast mechanism of such events, the software system for the implementation of the above theories and methods. Based on this research, the project is aimed at discovering the distribution and evolution patterns of our country's Internet TM, and explore the trend of Internet TM of the future. The accomplishment of the project will help us understand accurately and timely the evolution trends of Internet TM and thereby give adequate information to the policy agency for its decision making process. Furthermore, it will provide important guidance to various network researches, such as the network planning and optimal design, anomaly detection of the network flows, network reliability and capacity requirement analysis, and so on.
