带宽测量算法spruce源代码，能够实现对网络带宽的测量-Bandwidth measurement algorithm spruce source code, be able to achieve the measurement of network bandwidth

有较好的参考价值，IMC-PID是利用内模控制原理来对PID参数进行计算，最小均方误差（MMSE）的算法。-There are good reference value, IMC-PID control principle is to use the internal model to calculate the PID parameters, minimum mean square error (MMSE) algorithm.
