学术报告通知报告题目：Understanding Peer-to-Peer Resource Distribution in the Internet 报告人：Jiangchuan Liu，Associate Professor，School of Computing Science，Simon Fraser University, British Columbia, Canada 主持人：邱雪松教授时间：2010年6月17日(周四)上午9:30-11:30 地点：教三楼611会议室报告简介：The fast-growing traffic of peer-to-peer applications, most notably BitTorrent, is putting unprecedented pressure to Internet Service Providers (ISPs). Understanding the peer distribution over the global Internet thus becomes critical toward building new generation of ISP-friendly peer-to-peer systems. There are unfortunately significant scalability and representability challenges in measuring and understanding realworld peer distribution. In this talk, I will demonstrate a novel hybrid measurement methodology that uses the PlanetLab as a distributed probing platform to interact with BitTorrent trackers and peers in the global Internet. Our design achieves fast realtime scanning of genuine online peers; yet we carefully avoid the potential copyright-infringement and traffic overhead to the PlanetLab. From a 3-month data of over 9 million peers, we identify issues in conventional traffic locality designs, and also shed new lights on re-engineering BitTorrent trackers. I will also overview other related research projects in our group, including the measurement and enhancement of peer-to-peer video sharing, online map sharing, and software package distribution, as well as wireless network optimization. 此报告为前沿讲座，欢迎全校师生踊跃参加。校学术委员会网络研究院 2010年6月1日报告人简介： Jiangchuan Liu received the BEng degree (cum laude) from Tsinghua University, Beijing, China, in 1999, and the PhD degree from The Hong Kong University of Science and Technology in 2003, both in computer science.
