拓扑如下:
在该环境下,假设H1 ping H4,初始的路由规则是S1-S2-S5,一秒后,路由转发规则变为S1-S3-S5,再过一秒,规则变为S1-S4-S5,然后再回到最初的转发规则S1-S2-S5。通过这个循环调度的例子动态地改变交换机的转发规则。
pox脚本lab_controller.py
不得不说这脚本问题是真的多。

如果是在不同的机器使用的pox将控制器ip修改到对应pox所在的ip,我使用的是同一台计算机上的就直接修改成了127.0.0.1。
然后运行pox脚本再运行mininet脚本,得到下图:
mininet运行没啥问题,不过提示0丢包率是非法的emmmmm。 然后pox的内容有些奇怪,咋感觉少了一句的感觉。强迫症,到脚本里填上。在第260行填上一行输出。得到下图:
鉴于有人说,h1 ping不到 h4,就先pingall一下,得到下图:
一切正常。 然后继续实验,在mininet输入h1 ping -i 0.1 h4 每秒从h1传送10个包到h4。
mininet界面到时挺正常的,但是pox界面emmm一片死寂,所以我反复了几次,结果没有变化。估计不是pox出问题了,就是pox脚本写的有问题吧,难不成是我实验环境有问题?
由于对脚本内容了解的不够,所以我先尝试了一下使用poxdesk图形界面来显示结果。先安装一下。
1 cd ./pox/ext 2 git clone https://github.com/MurphyMc/poxdesk 3 cd poxdesk 4 wget http://downloads.sourceforge.net/qooxdoo/qooxdoo-2.0.2-sdk.zip 5 unzip qooxdoo-2.0.2-sdk.zip 6 mv qooxdoo-2.0.2-sdk qx 7 cd poxdesk 8 ./generate.py
我的小水管算是把我卡死了
然后通过命令运行:
1 ./pox.py 脚本名 web messenger messenger.log_service messenger.ajax_transport openflow.of_service poxdesk
然后进入浏览器查看:http://pox-ip:8000/poxdesk。这里pox-ip是pox所在的ip,如果本地就直接使用127.0.0.1就行。
观察s1目标为h4的,发现output一直在5和6之间变化,但是理论来说应该有三种不同的路由规则。结果很尴尬。。。
