我想在 Mininet 自定义拓扑上设置带宽。
蟒蛇代码是:
#!/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() ) }
但它有错误
------------------------------------------------------------------
Caught exception. Cleaning up...
TypeError: __init__() got an unexpected keyword argument 'bw'

我能做些什么?如何在 Mininet 自定义拓扑上设置带宽?
