1.安装OpenDayLight控制器,启动并安装插件
2.用Python脚本搭建如下拓扑
代码如下:
from mininet.topo import Topo
class MyTopo(Topo):
def __init__(self):
# initilaize topology
Topo.__init__(self)
# add hosts and switches
h1 = self.addHost('h1')
h2 = self.addHost('h2')
h3 = self.addHost('h3')
s1 = self.addSwitch('s1')
# add links
self.addLink(h1, s1, 1, 1)
self.addLink(h2, s1, 1, 2)
self.addLink(h3, s1, 1, 3)
topos = {'mytopo': (lambda: MyTopo())}
