(في الحزمة ذات الاسم نفسه) هو تقليل أزمنة الوصول بغض النظر عن حمل الشبكة. يتحقق هذا من خلال حد حركة البيانات الكلية إلى قيمة أصغر بقليل من قيمة إشباع الخط.

directives to the /etc/network/interfaces
file allowing declared commands to be run, respectively, after the interface is configured and before it is deconfigured. Or in the PPP case, creating a script that calls wondershaper

will enable traffic control as soon as the connection is up. Below is an example using this first method:
pfifo_fast
queue scheduler, which provides a few interesting features by itself. The priority of each processed IP packet is based on the DSCP field (Differentiated Services Code Point) of this packet; modifying this 6-bit field is enough to take advantage of the scheduling features.
