31 * $Id$ 32 * 33 * Description: The class to implement bandwidth and latency throttle. An 34 * instance of consumer class that can be woke up. It is only used 35 * to control bandwidth at output port of a switch. And the 36 * throttle is added *after* the output port, means the message is 37 * put in the output port of the PerfectSwitch (a 38 * intermediateBuffers) first, then go through the Throttle. 39 * | 30 * The class to implement bandwidth and latency throttle.
