+# AF using CBQ for a single interface eth0
+# 4 AF classes using GRED and one BE using RED
+# Things you might want to change:
+# - the device bandwidth (set at 10Mbits)
+# - the bandwidth allocated for each AF class and the BE class
+# - the drop probability associated with each AF virtual queue
+#
+# AF DSCP values used (based on AF draft 04)
+# -----------------------------------------
+# AF DSCP values
+# AF1 1. 0x0a 2. 0x0c 3. 0x0e
+# AF2 1. 0x12 2. 0x14 3. 0x16
+# AF3 1. 0x1a 2. 0x1c 3. 0x1e
+# AF4 1. 0x22 2. 0x24 3. 0x26
+
+#
+#
+# A simple DSCP-class relationship formula used to generate
+# values in the for loop of this script; $drop stands for the
+# DP
+# $dscp = ($class*8+$drop*2)
