用python文件创建mininet拓扑

topo.py

1. import os
   
2. def mininet():
   
3.     print "start"
   
4.     MN_CLI = "sudo mn --custom /home/ubuntu/sdn/mininet/mininet/custom/mytopo.py --topo mytopo --mac --controller=remote,ip=115.159.213.122,port=6633"
   
5.     body = os.popen(MN_CLI).readlines()
   
6.     print body
   
7.     return body
   
8. mininet()

命令行运行 sudo python topo.py
