The queuing discipline algorithm used in for implementing QOS in Bytton LTE is
classful
, meaning that it
includes several different classes of traffic, and can apply filters, in order to shape the traffic for each
class. The terminal classes in a particular queuing discipline are known as a leaf class by analogy to the
tree structure of the classes.
You can see below “leaf11”, “leaf12” and so on:
CLASS
class prio 1:1 parent 1: leaf 11:
class prio 1:2 parent 1: leaf 12:
class htb 12:11 parent 12:1 leaf 1211: prio 1 rate 600000bit ceil 1200Kbit burst 2Kb cburst 2Kb
class htb 12:1 root rate 1200Kbit ceil 1200Kbit burst 2Kb cburst 2Kb
class htb 12:13 parent 12:1 leaf 1213: prio 3 rate 240000bit ceil 1200Kbit burst 2Kb cburst 2Kb
class htb 12:12 parent 12:1 leaf 1212: prio 2 rate 360000bit ceil 1200Kbit burst 2Kb cburst 2Kb
Next, the filters associated to each class are shown:
