这个图是htb限速方式的处理方式的讲解图
queuing discipline (qdisc) - an algorithm that holds and maintains a queue of packets. It specifies the order of the outgoing packets (it means that queuing discipline can reorder packets). Qdisc also decides which packets to drop if there is no space for them
filter - a procedure that classifies packets. The filter is responsible for classifying packets so that they are put in the corresponding qdiscs
level - position of a class in the hierarchy
inner class - a class that has one or more child-classes attached to it. Inner classes do not store any packets, but they do traffic shaping. The class also does not have its own priority
leaf class - a class that has a parent but does not have any child-classes. Leaf classes are always located at level 0 of the hierarchy. Each leaf class has a qdisc, attached to it
self feed - an object that represents the exit for the packets from all the classes active at its level of the hierarchy. It consists of 8 self slots
self slot - an element of a self feed that corresponds to each particular priority. All classes, active at the same level, of one priority are attached to one self slot that they are using to send packets out through
active class (at a particular level) - a class that is attached to a self slot at the given level
inner feed - similar to self feed object, which consists of inner self slots, present on each inner class
inner feed slot - similar to self slot. Each inner feed consists of inner slots which represent a priority
是具体的说明，，，
