setup
enviornment
We tested the code on Ubuntu 16.04 machines running mininet version 2.2.1
- The entire design is centered around asynchronous tasks using the asyncio module, so the code requires Python 3.6.
To install the required Python 3 packages, run:
pip3 install --user aioconsole==0.1.3 ecdsa==0.13
- mininet is not available with Python 3, so part of the code also requires Python 2.
To install the required Python 2 packages, run:
pip2 install --user mininet==2.2.1
- Apart from this, ensure that mininet is properly setup.
running the code
In a terminal window, run:
sudo python2 start_network.py 10
This will spawn 10 nodes (each with a separate xterm.)
The start_network terminal provides a REPL that can be used to modify the network - add, remove nodes etc.
The first spawned xterm has another REPL that allows us to execute RPCs on a host. This can be used to demo money transfer etc.
Both REPL interfaces have a help command that lists all available commands and their usage.
