2019 SDN上机第4次作业

1.解压配置Java环境

sudo gedit ~/.bashrc
在bashrc文件底部添加java路径

2.安装插件

安装feature
feature:install odl-restconf odl-l2switch-switch-ui odl-openflowplugin-all odl-mdsal-apidocs odl-dlux-core odl-dlux-node odl-dlux-yangui

3.用Python编写代码

from mininet.topo import Topo
class Mytopo(Topo):
    def __init__(self):
        Topo.__init__(self)
        sw=self.addSwitch('s1')
        count=1
        for i in range(3):
                host = self.addHost('h{}'.format(count))
                self.addLink(host,sw,1,count)
                count = count + 1
topos = {'mytopo': (lambda:Mytopo())}

执行以下命令
sudo mn --custom /home/mowei/1.py --topo mytopo --controller=remote,ip=127.0.0.1,port=6633 --switch ovsk,protocols=OpenFlow13
