python - 如何在Mininet自定义拓扑上设置带宽？

我想在Mininet自定义拓扑上设置带宽。

python代码是:

#!/usr/bin/python
from mininet.topo import Topo
from mininet.net import Mininet
from mininet.node import CPULimitedHost
from mininet.link import TCLink
from mininet.util import dumpNodeConnections
from mininet.log import setLogLevel

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

    def __init__( self, **opts):
        "Create custom topo."

        # Initialize topology
        Topo.__init__( self, **opts )

        # Add hosts and switches
        h1 = self.addHost('h1')
        h2 = self.addHost( 'h2' )

        s3 = self.addSwitch( 's3' )
        s1 = self.addSwitch( 's1' )
        s2 = self.addSwitch( 's2' )

        # Add links
        self.addLink(h1,s1,bw=10)
        self.addLink(h2,s3,bw=20)
        self.addLink(s3,s2,bw=10)
        self.addLink(s1,s3,bw=10)

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

但是有错误

------------------------------------------------------------------
Caught exception. Cleaning up...
TypeError: __init__() got an unexpected keyword argument 'bw'
------------------------------------------------------------------

我能做什么？

最佳答案

您应该使用--link参数。例如:sudo mn --topo tree,depth=2,fanout=5 --controller=remote,ip=10.0.0.1,port=6633 --switch ovsk,protocols=OpenFlow13, --link tc,bw=1,delay=10ms
我将尽快举例说明。
