Network Measurements, Modeling and Simulations

Spring 2014, Room 4260, 14:10~17:00 Thursday

Instructor: Kun-chan Lan
(this course is offered in English)

Objectives

  • Targeting audience: graduate students who are interested in pursuing research in networking.
  • Aim: introduce the whole process of an experimental research cycle from problem identification, proposing solution, experiment design, to finally evaluate the proposed solutions in the simulations or emulation.
  • We will cover basic techniques in experimental design, measurements, modeling and simulations. A number of tools frequently used in network research will be introduced.

Scope

  • Measurement strategies and techniques
  • Principles of network modeling
  • Fundamental of experimental design and performance evaluation
  • A collection of network research tools
  • Measurement tool: ping, traceroute, iperf
  • Collection tool: tcpdump, ethereal
  • Simulation: NS-2
  • Emulation: Nisnet, dummynet
  • Testbed: TinyOS/mote, Netfilter

Recommended reading

  • If you don't have sufficient background, try to review the following books
  • Computer Networks: A Systems Approach (Morgan Kaufmann Series in Networking), 3rd Edition, Larry L. Peterson and Bruce S. Davie , ISBN 1-55860-833-8
  • Computer Networking: A Top-Down Approach Featuring the Internet, 3rd Edition, James F. Kurose, Keith W. Ross, and Addison Wesley, ISBN 0-201-97699-4
