Mininet中文使用教程

上面的输出中包含交换机的虚拟网卡 s1，以及主机的 eth0。

为了区别显示host 主机的网络是隔离的，我们可以通过arp与route命令来做演示，分别在 s1与h1上面演示如下：

这样可以做到将每一个主机，交换机，以及控制器都放到他自己的标准的 network

namespace 中，但是这种做法并没有什么特别的优势，除非你想复制一个非常复杂的网络。Mininet 不支持这种做法，你可以通过--innamespace参数来查看更多的信息。

译者注：感觉有点像 LXC 或者说想最近比较火的 Docker

注意:只有网络是虚拟出来的，每一个主机里面的进程使用的都是同一套目录，可以看到相同的进程集合，我们打印不同主机下面的进程列表看看：
