SDN2017 第二次实验作业

安装floodlight

参考链接：http://www.sdnlab.com/19189.html

从github下载源码，并编译安装

$ sudo apt-get install build-essential ant python-dev
$ wget https://codeload.github.com/floodlight/floodlight/zip/v0.91 -o floodlight.zip
$ unzip floodlight.zip
$ cd floodlight 
$ ant

成功编译后运行并访问http://localhost:8080/ui/index.html

$ java -jar target/floodlight.jar

生成拓扑并连接控制器floodlight，利用控制器floodlight查看图形拓扑

由上图的目标拓扑编写代码如下

#!/usr/bin/python
__author__ = "tr3e"

from mininet.topo import Topo

class MyTopo( Topo ):

def __init__( self ):

    Topo.__init__( self )
    
    s1 = self.addSwitch('s1')
    s2 = self.addSwitch('s2')
    s3 = self.addSwitch('s3')
    s4 = self.addSwitch('s4')

    h1 = self.addHost('h1')
    h2 = self.addHost('h2')
    h3 = self.addHost('h3')

    self.addLink(h1,s2,1,1)
    self.addLink(h2,s3,1,1)
    self.addLink(s2,s1,2,1)
    self.addLink(s3,s1,2,2)
    self.addLink(s1,s4,3,1)
    self.addLink(s4,h3,2,1)
topos = { 'mytopo': ( lambda: MyTopo() ) }

运行mininet生成上述拓扑
