这是我们在Mininet上试验时所用的工具箱。

topo.py是一个拓扑生成工具。可以使用

  'python topo.py -h xx -s yy'

来生成一个新的拓扑。对于'-h'和'-s'并没有顺序要求。'-h'后的xx代表
新拓扑中的主机数，'-s'后的yy则代表新拓扑中的交换机数量。新拓扑为
线性，每台主机都与编号相同的交换机相连。如果主机数量多于交换机数
量，则第n+1台主机连接到第1个交换机。

scp_dhcp是DHCPDISCOVER包生成代码。可以在代码中

	'sendp(dhcp_disc, loop=1, inter=0.2)'

调整是否循环和发送时延。其中，loop为循环控制（1=循环; 0=不循环）。
inter为间隔时间。

This is a tool-box for our experiments/stimulations on Mininet.

topo.py is a topo-gen tool. You can use 
  'python topo.py'

to generate a new topology. There is no restrict on the order of
'-h' and '-s'. The xx after '-h' is the number of hosts in that
topo, and yy after '-s' the number of switches. The new topo is 
linear topology, and each host is connect with a switch which have
the same number. If there are more hosts than switches, then the
(n+1)th host will connect to 1st switch.

scp_dhcp is a piece of DHCPDISCOVER packet generating code. You
can adjust in

	'sendp(dhcp_disc, loop=1, inter=0.2)'

where loop=1; loop=0 are enable and disable looping. And inter
controls the interval time between packets.
