3 About Myself Graduated from Tsinghua University in 1992
Joined Dept. of CS since graduated Research Area Networking: design/analysis Network management, network measurement In charge of the NOC of CERNET from Teaching 计算机网络原理 for Undergraduates, 1995, 1997 网络测量与分析技术 for Graduates, 2008,2009, 2010,2011,2012,2013 Contact web: office: FIT 3-210, 83492

4 Goals 全面了解网络测量与分析以及网络行为学研究领域的热点问题 在掌握计算机网络原理的基础上深入学习网络测量技术
基本掌握该领域最新研究成果 初步了解和掌握网络测量与分析领域中的基本研究方法 能够独立开展网络测量领域的相关研究工作

5 Topics Background Infrastructure measurement Traffic measurement
Networking review and measurement motivation Analytical background Infrastructure measurement ISP relationships, topology modeling, network tomography Traffic measurement Self-similarity & heavy tails, traffic matrix, sampling and flow measurement Application measurement Web , P2P, OSN Measurement application Anomaly detection Multipath routing

6 Schedule 1、网络测量引论 (9.25) 2、网络测量基础设施与体系结构 (10.9) 3、统计分析工具简介(略)
网络性能测量综述 (10.11(周六)) 4、网络流量测量综述(10.16) 5、网络性能测量(一):End-to-End Path Characterization(指标体系, Loss, Delay) (10.23) 6、网络性能测量(二):Bandwidth Measurement(10.30) 7、网络性能测量(三):Network Tomography (11.6)

7 Schedule 8、网络流量测量(一):Traffic Modeling: Self-similarity and long-range dependence (LRD) (11.13) 9、网络流量测量(二):Sampling & Flow Measurement (11.20) 10、网络流量测量(三):Traffic Matrix (11.27) 11、路由测量与路由动态性分析 (12.4) 12、网络拓扑测量与建模 (12.11) 13、面向应用的测量:社交网络测量分析(12.18) 14、测量应用:异常检测(12.25) 13、测量应用:多路径路由与自适应路由 (12.18) –取消了。

8 Approach Lecture/Paper discussions Reading Cover the fundamentals
Interactive discussions from you 分组讨论:每周一次,每次一个组(2~3人),每人均需就一篇文章(或一个主题)做Presentation 从第4次课开始 Reading Not all papers will be discussed in class. Background material (may be required for assignments/projects) 每人任选非主讲主题的文章5篇(要分布在不同的主题),阅读并写出读书报告(>=500字)

9 Approach(Cont.) Project (以下三个任选) 就分组讨论所选的主题,做比较全面的调研综述,最后写出综述报告
实现一个简单的网络性能测量系统,给出设计和实现报告(可以基于现有的工具:NDT、OWAMP、BWCTL) 对所提供的部分网络流量进行分析,给出设计和实现报告 第10或11周左右要先通过简单的Presentation介绍一下思路 以小组为单位
