All Implemented Interfaces:
BandwidthEstimator
```
class SimpleBandwidthEstimator
extends Object
implements BandwidthEstimator
```
A Westwood+ bandwidth estimator with a first stage anti-aliasing low pass filter based on RTT, and the time-varying Westwood filter based on inter-arrival time.

- Method Detail
  - addSample
```
public void addSample(int acked)
```
    Records an arriving ack.
    Specified by:
    addSample in interface BandwidthEstimator
    Parameters:
    acked - how many packets were acked with this ack
  - getBandwidthEstimate
```
public float getBandwidthEstimate()
```
    Description copied from interface: BandwidthEstimator
    Get the current bandwidth estimate.
    Specified by:
    getBandwidthEstimate in interface BandwidthEstimator
    Returns:
    the current bandwidth estimate in packets/ms.
  - getDecayFactor
```
public static int getDecayFactor()
```
    Returns the current EWMA decay factor.
    Returns:
    the current decay factor
  - setDecayFactor
```
public static void setDecayFactor(int factor)
```
    Sets the EWMA decay factor for new estimators. Higher = more smoothing, lower = faster adaptation.
    Parameters:
    factor - the new decay factor (clamped to 2..16)
  - toString
```
public String toString()
```
    toString.
    Overrides:
    toString in class Object
