Greetings Claudiu!

> I'm Claudiu, a second year PhD student in CS at Sapienza University (Rome, Italy) and I would like to work on your GSOC idea to build a VB-based simulator for OONI. My main research topics are network neutrality and broadband measurement and I'm currently working on a project on traffic shaping detection. I also partecipated to last year GSOC when I developed in Python a server selection mechanism for M-Lab (https://code.google.com/p/m-lab/source/browse/?repo=ns).

This is very relevant to the OONI areas of research.

Netkit is an open source project,based on user-mode linux[1], a linux kernel that can be executed as a user  process on a standard linux box. In particular, each virtual machine in Netkit can be configured to play the role of a regular host, of a router, or even of a switch.  For this project, each test could be set up as a ‘netkit lab’, which is a set of preconfigured virtual machines that can be started and halted together. For example, one virtual machine running ooniprobe could be connected to the external world through a second virtual machine that implements various censorship policies, specific to each test.

Netkit does seem like a good choice for doing this. Making this work on the basis of Netkit would probably be a matter of writing a set of NetML descriptions for the various censorships we are interested in simulating.

BTW I am currently in Rome and would be up for meeting up someday to perhaps discuss this in person further or hack on it together.
