我使用了git安裝node
git clone git://github.com/mininet/mininet
mininet/util/install.sh -a
sudo mn --topo linear,3
sudo.mn --topo tree,fanout=3,depth=2
from mininet.topo import Topo from mininet.net import Mininet from mininet.node import RemoteController,CPULimitedHost from mininet.link import TCLink from mininet.util import dumpNodeConnections class MyTopo( Topo ): "Simple topology example." def __init__( self ): "Create custom topo." # Initialize topology Topo.__init__( self ) L1 = 2 L2 = L1 * 2 #L3 = L2 c = [] a = [] #e = [] # add core ovs for i in range( L1 ): sw = self.addSwitch( 's{}'.format( i + 1 ) ) c.append( sw ) # add aggregation ovs for i in range( L2 ): sw = self.addSwitch( 's{}'.format( L1 + i + 1 ) ) a.append( sw ) # add links between core and aggregation ovs for i in range( L1 ): sw1 = c[i] for sw2 in a[i/2::L1/2]: # self.addLink(sw2, sw1, bw=10, delay='5ms', loss=10, max_queue_size=1000, use_htb=True) self.addLink( sw2, sw1 ) #add hosts and its links with edge ovs count = 1 for sw1 in a: for i in range(2): host = self.addHost( 'h{}'.format( count ) ) self.addLink( sw1, host ) count += 1 topos = { 'mytopo': ( lambda: MyTopo() ) }
本次實驗較爲簡單,基本上按照給定的操做循序漸進,配置好合適的環境就能夠順利完成做業。python
