Build the mini-Internet

To build the mini-Internet, first clone the mini-Internet repository to your server, and go to the platform directory.

git clone [email protected]:nsg-ethz/mini_internet_project.git
cd mini_internet_project/platform/

Don't forget to check the prerequisite page.

After editing the configuration files, run the startup script:

sudo ./startup.sh

By default, this will run a mini-Internet with 12ASes (default configuration files). When building the mini-Internet, a directory called groups is created and all the configuration files, passwords, automatically-generated scripts, etc will be stored in this directory.

⚠️ Make sure your server has enough resources to sustain the configured mini-Internet (around 16GB of memory and at least 4 CPU cores are recommended for the default setup). Otherwise, you can configure a smaller mini-Internet using the previously introduced configuration files.

ℹ️ You may need to increase the number of INotify instances that can be created per real user ID with the command

sudo sysctl fs.inotify.max_user_instances=1024

Default configuration

Using the default configuration, most of the hosts, routers and switches will come preconfigured and there will be nearly full connectivity. We explain how to change the default configuration (the topology and the various parameters) in the Configure the mini-Internet section.
