Speaker: S. H. Gary Chan, Department of Computer Science and Engineering The Hong Kong University of Science and Technology (HKUST) Title: Proxy-P2P Live Streaming Date/time: 4:30pm on Thursday June 25th Location: B-205 in the E-Quad Abstract: Peer-to-peer (P2P) is a promising technique for live streaming to large distributed group (such as IPTV services). In this talk, we address the design of a proxy-based peer-to-peer (proxy-P2P) streaming network, where the proxies (or super-nodes) are used as "backbone" to carry streams to local users (peers). Users, after mapping to their nearby proxies, get their streams in a peer-to-peer manner. We investigate how to achieve bandwidth-efficient low-delay streaming in such a network. At the proxy level, we study the use of mesh to achieve a certain streaming rate requirement. Since the delay is the slowest path from the source, we design a distributed algorithm called FastMesh which seeks to minimize the worst-case delay of the proxies. At the peer level, we propose and study an efficient distributed algorithm called SIM (Scalable Island Multicast) which combines overlay with IP-multicast. Through simulation and PlanetLab experiments, we show that our algorithms substantially outperform traditional and state-of-the-art approaches. At HKUST, we are currently implementing such a proxy-P2P streaming network and I will share our experience on that at the end of the talk.

Wing President's Professor of Computer Science, Computer Science Department, Carnegie Mellon University Assistant Director, Computer and Information Science and Engineering Directorate, National Science Foundation Abstract: The NSF Computer and Information Science and Engineering Directorate funds 84% of all academic computer science research in the United States. I will present highlights of CISE's research and education programs, including current interests in cyber-enabled discovery and innovation, cyber physical systems, data-intensive computing, network science and engineering, socially intelligent computing, and trustworthy computing; and future interests in information technology's role in energy and the environment and the intersection of computer science and economics. I will also put NSF's investments in computing within the broader national and international context. Bio: Dr. Jeannette M. Wing is the President's Professor of Computer Science in the Computer Science Department at Carnegie Mellon University. She received her S.B. and S.M. degrees in Electrical Engineering and Computer Science in 1979 and her Ph.D. degree in Computer Science in 1983, all from the Massachusetts Institute of Technology. From 2004-2007, she was Head of the Computer Science Department at Carnegie Mellon. Currently on leave from CMU, she is the Assistant Director of the Computer and Information Science and Engineering Directorate at the National Science Foundation. Professor Wing's general research interests are in the areas of specification and verification, concurrent and distributed systems, programming languages, and software engineering. Her current focus is on the foundations of trustworthy computing. Professor Wing was or is on the editorial board of eleven journals. She has been a member of many advisory boards, including: the Networking and Information Technology (NITRD) Technical Advisory Group to the President's Council of Advisors on Science and Tecbnology (PCAST), the National Academies of Sciences's Computer Science and Telecommunications Board, ACM Council, the DARPA Information Science and Technology (ISAT) Board, NSF's CISE Advisory Committee, Microsoft's Trustworthy Computing Academic Advisory Board, and the Intel Research Pittsburgh's Advisory Board.
