使用Python Mininet 建立網路模擬環境

該模擬環境為20台Host,1台Controller,1台Switch


#!/usr/bin/python

from mininet.net import Mininet
from mininet.node import RemoteController
from mininet.node import OVSKernelSwitch
from mininet.cli import CLI
from mininet.util import dumpNodeConnections


if __name__ == '__main__':
    net = Mininet()
    c1 = net.addController('c1', controller=RemoteController)
    s1 = net.addSwitch('s1', cls=OVSKernelSwitch)

    for n in xrange(1, 21):
        host = net.addHost('h%s' % n)
        net.addLink(host, s1)

    net.build()

    c1.start()
    net.get('s1').start([c1])
    dumpNodeConnections(net.hosts)
    CLI(net)

    net.stop()


執行結果:
