摘要:
The Internet has transformed itself into a critical global information infrastructure, and fundamentally altered the ways we access information, communicate and interact with each other, purchase goods and services, and entertain ourselves. Despite its enormous success, the Internet suffers certain well-known shortcomings, and is increasingly strained to meet the high availability, reliability, mobility, manageability and security demands of Internet applications, users, and service providers alike. Much of my research is centered on addressing the challenges posed by these new demands. This talk consists of two parts. In the first part, I will provide a brief overview of the on-going network research in my group, including the echnical trends driving our research, and some specific projects we're currently pursuing. In the second part, I will focus on one important sub-area of our research, namely, mining network data for network management and security. As Internet communications and applications become more complex, operating, managing and securing networks have become increasingly challenging tasks. There are urgent demands for more sophisticated techniques for understanding and analyzing the behavioral characteristics of network traffic. As an example of such a technique we have developed, we studied the network traffic behaviors using traffic activity graphs (TAGs), which capture the interactions among hosts engaging in certain types of communications and their collective behavior.

简历:
Zhi-Li Zhang received the B.S. degree in computer science from Nanjing University, China, in 1986 and his M.S. and Ph.D. degrees in computer science from the University of Massachusetts, in 1996. In 1997 he joined the Computer Science and Engineering faculty at the University of Minnesota, where he is currently the Qwest Chair Professor in Telecommunications. Prof. Zhang's research interests lie broadly in computer communication and networks, Internet technology, multimedia and emerging applications. Prof. Zhang has served on the Editorial board of IEEE/ACM TransactionTransactions on Networking, Elsevier's Computer Network, an International Journal, and Chinese Academy of Science's Journal of Computer Science and Technology. He was Technical Program Co-chair of IEEE INFOCOM 2006 and ACM/USENIX IMC 2008. He received the National Science Foundation CAREER Award in 1997. He has also been awarded the prestigious McKnight Land-Grant Professorship and George Taylor Distinguished Research Award at the University of Minnesota, and the Miller Visiting Professorship at Miller Institute for Basic Sciences, University of California, Berkeley. Prof. Zhang is co-recipient of an ACM SIGMETRICS best paper award, an IEEE ICNP best paper award, and an IEEE INFOCOM best paper award.
