2019 SDN上机第4次作业

1. 解压安装OpenDayLight控制器

Java配置

解压安装OpenDayLight控制器（本次实验统一使用Beryllium版本）

2. 启动并安装插件

3. 用Python脚本搭建如下拓扑，连接OpenDayLight控制器

python代码

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

class MyTopo(Topo):

    def __init__(self):

        # initilaize topology
        Topo.__init__(self)
	
	s=[]
	for i in range(1):
            sw = self.addSwitch('s{}'.format(i+1))
            s.append(sw)
	count=1 
        for i in range(3):
            host = self.addHost('h{}'.format(count))
            self.addLink(s[0],host)
            count += 1
      
        
topos = {'mytopo': (lambda: MyTopo())}
