net.floodlightcontroller.counter.SimpleCounter
This is a simple counter implementation that doesn't support data series. The idea is that floodlight only keeps the realtime value for each counter, statd, a statistics collection daemon, samples counters at a user-defined interval and pushes the values to a database, which keeps time-based data series. @author Kanzhe
