这歌代码没有报错，可是，控制器只能连接到ovs,在mininet中用hosts去pingall的时候就会一下连接，一下断开，无法ping通。

于是就简化了一下代码，去掉觉得有bug的代码，抛出的异常是没有实例化；

代码如下：

returnTrafficAnalyser.class.getSimpleName（）;

publicCollection<

publicvoidstartUp（FloodlightModuleContextcontext）{

if（CounterValue.CounterType.LONG==v.getType（））{

model.put（counterName,v.getLong（））;

model.put（counterName,v.getDouble（））;

（ICounterStoreService）getContext（）.getAttributes（）.

用

sudomn--toposingle,3--mac--switchovsk--controller=remote,ip=10.0.2.15,port=6633

建立hosts去pingall
