问题 I am new to SDN, Environment- I have 2 VMs(VM Ware) running on my Windows 10(laptop). One is Mininet and another is Opendaylight(in Ubuntu). I made a simple topology through mininet and connected it to the controller and I can see the topology in Opendaylight Controller. Topology: 3 switches, 4 hosts and 1 controller.Please click here to see topology Question- I know that through controller we can manage the switches, change the configuration, etc. so exactly we can do that through GUI of the

1.安装Karaf,MVN（新版MVN不是必须了） http://archive.apache.org/dist/karaf/3.0.8/apache-karaf-3.0.8.tar.gz http://archive.apache.org/dist/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz mkdir ~/Applications tar -zxvf apache-karaf-3.0.8.tar.gz -C ~/Applications/ tar -zxvf apache-maven-3.3.9-bin.tar.gz -C ~/Applications/ 2.安装install Oracle Java 8 及MVN 1. Download and Extract JDK package, such as jdk-8u131-linux-x64.tar.gz, and you can see new directory /home/yourname/jdk1.8.0_131 2. Add two environment variables into ~/.bashrc or /etc/profile: export JAVA_HOME=/home/yourname/jdk1.8.0_131 export

建一个简单的模型，使用一个单交换机，然后链接n个主机形成拓扑，然后对每个链路设置带宽，延迟时间，和丢包率。 这里就选择建一个单交换机和六个主机的作为例子。 创建py脚本生成拓扑：写一个类生成一个单交换机和六个主机的拓扑，并且给每个主机和交换机之间的连接赋予100m的带宽，5ms的延迟和1%的丢包率。然后通过pingall函数测试连接，iperf函数测试主机间的带宽， 1 from mininet.topo import Topo 2 from mininet.net import Mininet 3 from mininet.node import CPULimitedHost 4 from mininet.link import TCLink 5 from mininet.util import dumpNodeConnections 6 from mininet.log import setLogLevel 7 8 9 class SingleSwitchTopo(Topo): 10 def __init__ (self, n=2, ** opts): 11 Topo. __init__ (self, ** opts) 12 switch = self.addSwitch( ' s1 ' ) 13 for h in range(n): 14 # Each host gets
