Python을 이용한 Mininet Topology 작성

1. Topology

2. Python 코딩하기 (ex1.py)

from mininet.topo import Topo

class SDNProjectTopo(Topo):
     def __init__(self):
        Topo.__init__(self)
        h1 = self.addHost('h1')

        h2 = self.addHost('h2')



        s1 = self.addSwitch('s1')

        s2 = self.addSwitch('s2')

        s3 = self.addSwitch('s3')

        s4 = self.addSwitch('s4')



        self.addLink(h1,s1)

        self.addLink(s1,s2)

        self.addLink(s1,s3)

        self.addLink(s2,s4)

        self.addLink(s3,s4)

        self.addLink(s4,h2)



topos = {'mytopo':(lambda:SDNProjectTopo())}

3. Mininet 작성한 코드로 실행하기

$sudo mn --custom=ex1.py --topos=mytopo

4. ODL 연결하고 Topology 확인하기

$sudo mn --custom=ex1.py --topos=mytopo --controller=remote,ip=127.0.0.1,port=6633
