Computer Networking Hands-on material

Applets

These applets are originally from Kurose and Ross Computer Networks reproduced locally with thanks. Chapter references are to the Kurose and Ross book.

• Transmission vs Propagation Delays
• Interactive Queues and Loss
• Go-Back-N Protocol
• Selecive Repeat
• Flow Control

While this subject has no formal practicals there is considerable merit in learning by doing. This page will contain material of a practical (hands-on) nature.

Mininet

As in past years, I would encourage students to try Mininet. Developed by colleagues at Stanford, some interesting material is available at http://teaching.mininet.org/

The tutorial VM Images are mirrored here:

• 32 bit: http://www.scs.stanford.edu/~jvimal/mininet-sigcomm14/mininet-tutorial-vm-32bit.zip CUCL Mirror
• 64 bit: http://www.scs.stanford.edu/~jvimal/mininet-sigcomm14/mininet-tutorial-vm-64bit.zip CUCL Mirror

A good starting point is the Sigcomm 2014 Mininet tutorial and specifically the examples

• BGP Attack Demo (or "How to own the Internet, at least until the authorities arrive")
• Bufferbloat (or "what does my interactive shooter get fragg'd when someone else does windows update")

More advanced students (or those with more free time) are directed toward

• Simple Router
• Implementing a NAT
• Implementing a small routing protocol (PWOSPF)

Recent experience suggestions ContainerNet (Mininet in a container) is an more robust place to work but a little less well documented.

Standard stuff

• Wireshark Labs-sheets - not bad for ideas but the pitch point is an American Liberal Arts College, interpret that as you wish.
