2.  Students will write a network monitoring tool to supervise network traffic  Open source is one of the keywords in the industry  Students will be using publicly open sources to create their programs

3.  Make an utility to monitor network traffics passing at your interesting points  Not only traffic flowing into you but flowing to other nodes in the network  Monitoring parameters  Instant bandwidth  The number of packets in protocols TCP, UDP and SCTP  The number of packets in ports numbers  Bandwidth in a flow  Bandwidth in a stream  What are the stream and the flow?

4.  L7 packet classifier  What on earth is it?  Applications in interest  P2P  Internet telephony SKYPE  Any applications you can imagine

5.  libpcap  libpcap is a system-independent interface for user-level packet capture. libpcap provides a portable framework for low-level network monitoring  Download this package at http://www.tcpdump.org/  RRDtool  RRDtool is the Open Source industry standard, high performance data logging and graphing system for time series data.  Download this package at http://oss.oetiker.ch/rrdtool/

7.  LINUX only  Must make use of MAKEFILE  I will try to make a testbed for you  In the meantime, you must seek your own testbed

8.  Upload your source code  taeku.skku.ac.kr or 203.255.252.170  classes/fa2009/computer_networks/project  Use “anonymous” as a login ID  Tar and gzip you files You may have multiple files Makefile, too  The name of the file must be your_school_id.tar.gz  Be careful when you upload your source as you may not able to upload your source again at the same file name.  Do not even think about copying other’s code.

9.  Report  Complete the report in MS Word and upload onto “iCampus”.  Name your file as your_Korean_name.doc.  Do not zip your file.  Include  Screenshot of successful FTP session  Overall description of your code  Your unique experience  Plots of monitoring parameters  Describe your effort for the extra credit if available
