mininet和ryu简单实现自定义topo

设备名称 软件
ubuntu16.04 host1 mininet
ubuntu16.04 host1 ryu controller 
远成连接xshell 开两个窗口 一个窗口开ryu 一个窗口使用 mininet

步骤1. 窗口1下 在/mininet/custom/ 下编写一个简单的topo python文件example.py

	example.py 代码

#!/usr/bin/python

from mininet.topo import Topo
from mininet.net import Mininet
from mininet.node import RemoteController
from mininet.link import TCLink
from mininet.util import dumpNodeConnections

class MyTopo( Topo ):
    "Simple topology example."

    def __init__( self ):
        "Create custom topo."

        # Initialize Topology
        Topo.__init__( self )

        # Add hosts and switches
        Host1 = self.addHost( 'h1' )
        Host2 = self.addHost( 'h2' )
        Host3 = self.addHost( 'h3' )
        Switch1 = self.addSwitch( 's1' )
        Switch2 = self.addSwitch( 's2' )

        # Add links
        self.addLink( Host1, Switch1 )
        self.addLink( Host2, Switch1 )
        self.addLink( Host3, Switch2 )
        self.addLink( Switch1, Switch2 )

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

步骤2. 窗口2下 启动ryu

步骤3. 窗口1下 执行你的t自定义的网络topo结构
