Project structure Spring 2013

www.cs.helsinki.fi

• Step 1: Learn to use wireshark

• use sample captures

• use exiting filters and create at least one own filter

•Step 2: Capture and analyse traffic

•Use a virtual machine in our NODES cloud (OpenStack-based) to capture some network traffic you created, capturing with tcpdump

• Use Wireshark to analyse the traffic

Initial phase: Introductory task

www.cs.helsinki.fi

• Group size 11 students• preset maximum 10, but accepted all 11 applicants, 9 finished the project

• First-year to N-year bachelor students• heterogeneous group

• strong own interest to communication aspects

• Only formal prerequisite: the intro to data comm. course

• additional requirements (grade level, study progress) not used

Attending students & prerequisites

www.cs.helsinki.fi

• Followed the model given in initial phase

• Capture traffic

• Few minutes to several hours

• Filter during capture (or not)

• Use wireshark to analyse the captured traffic

• Number of messages

• Traffic volume

• Traffic distribution

• Create graphs with wireshark to show results

Student projects

www.cs.helsinki.fi

• Excellent posters

• Poster examples shown in advance

• Feedback on drafts

• Most students did their first poster

• Some posters in English, mainly in Finnish (students were allowed to select the language)

• Poster session: 3 min presentation + 5 min discussion (then next poster)
