HTB terms:
• 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
Each class has a parent and may have one or more children. Classes that do not have children, are
put at level 0, where queues are maintained, and are called 'leaf classes'
Each class in the hierarchy can prioritize and shape traffic. There are 2 main parameters in
RouterOS which refer to shaping and one - to prioritizing:
