-A custom solution for fixing external Bufferbloat by dynamically adjusting QoS Pipes.

+A custom solution for fixing external Bufferbloat by dynamically adjusting QoS Pipes.  
+
+This script makes several assumptions:  
+- Maximum Download Bandwidth: 80Mbit/s 
+- Maximum Upload Bandwidth: 20Mbit/s 
+- Minimum Download Bandwidth: 5Mbit/s 
+- Minimum Upload Bandwidth: 2Mbit/s 
+- Optimal Ping: <= 50ms
+- Critical Ping: >= 200ms  
+- downloadPipe=10000 & uploadPipe=10001 (see output of: ipfw pipe show)
+  
+You may change the corresponding variables, but be aware of unit convertion loss!  
+  
+## How this script works
+The initial trivial idea:  
+- If average ping is >200ms, reduce current download bandwidth by 10%  
+- repeat until ping is OK or lower limit reached  
+- If average Ping <50ms -> Increase Bandwidth by 10% until upper limit reached
