mntopod

mininet topology daemon : get a live graphical representation of your mininet topologies and flows in your browser in ~30 secondes

Usage

mntopod includes three components : backend, middleware and client.

The client is a webpage that you can host somewhere or just open in your browser (Ctrl-O).

The middleware is a single nodejs file that you need to run somewhere reachable from the mininet VM and your client.

cd middleware && npm install && npm start

The backend is a single python file that you include in your mininet topology.

Instanciating MininetTopologyDaemon is the only step needed. The IP is the IP of the middleware, and the port number is optional.

Example :

#!/usr/bin/python
from mininet.net import Mininet
from mininet.cli import CLI
from mininet.log import setLogLevel, info

from mntopobackend import MininetTopologyDaemon

def myNetwork():

    net = Mininet(topo=None, build=False, controller=None)
    s1 = net.addSwitch('s1')
    h1 = net.addHost('h1')
    net.addLink(h1, s1)
    net.start()
   
    mntopod = MininetTopologyDaemon(net, '10.0.2.1', 3141)
    CLI(net)
    mntopod.stop()
    net.stop()

if __name__ == '__main__':
    setLogLevel( 'info' )
    myNetwork()

A typical setup, using the Mininet VM, would be deploying the middleware and client on your host while running your custom topologies in the VM.
