在mininet中动态移动主机

Question

如何在mininet中动态移动主机？是否有CLI命令或脚本？我在https://github.com/mininet/mininet/blob/master/examples/mobility.py上尝试了代码，但得到了这个错误：

anusha@anusha-Lenovo-IdeaPad-Z500:~$ sudo python ~/mininet/custom/mobility.py 
* Simple mobility test
* Starting network:
s1: h1(1) s2(2) 
s2: h2(1) s1(2) s3(3) 
s3: h3(1) s2(2) 
* Testing network
*** Ping: testing ping reachability
h1 -> h2 h3 
h2 -> h1 h3 
h3 -> h1 h2 
*** Results: 0% dropped (6/6 received)
* Identifying switch interface for h1
* Moving h1 from s1 to s2 port 13
Traceback (most recent call last):
  File "/home/anusha/mininet/custom/mobility.py", line 128, in <module>
    mobilityTest()
  File "/home/anusha/mininet/custom/mobility.py", line 115, in mobilityTest
    hintf, sintf = moveHost( h1, old, new, newPort=port )
  File "/home/anusha/mininet/custom/mobility.py", line 96, in moveHost
    oldSwitch.moveIntf( sintf, newSwitch, port=newPort )
  File "/home/anusha/mininet/custom/mobility.py", line 77, in moveIntf
    switch.attach( intf )
  File "/home/anusha/mininet/custom/mobility.py", line 45, in attach
    if self.isOldOVS():
AttributeError: 'MobilitySwitch' object has no attribute 'isOldOVS'

谢谢!

在做了大量研究后，我发现在mininet中没有直接的命令、函数或脚本来促进主机在网络中的移动。

相反，您可以做的是模拟主机的移动！mininet> link h1 s1 down ---->does only logical link down mininet> py net.addLink(s2,net.get(h1))

您可以开始了:)
