-.SH DESCRIPTION
-Class Based Queueing is a classful qdisc that implements a rich
-linksharing hierarchy of classes. It contains shaping elements as
-well as prioritizing capabilities. Shaping is performed using link
-idle time calculations based on the timing of dequeue events and
-underlying link bandwidth.
-
-.SH SHAPING ALGORITHM
-Shaping is done using link idle time calculations, and actions taken if
-these calculations deviate from set limits.
-
-When shaping a 10mbit/s connection to 1mbit/s, the link will
-be idle 90% of the time. If it isn't, it needs to be throttled so that it
-IS idle 90% of the time.
-
-From the kernel's perspective, this is hard to measure, so CBQ instead
-derives the idle time from the number of microseconds (in fact, jiffies)
-that elapse between requests from the device driver for more data. Combined
-with the knowledge of packet sizes, this is used to approximate how full or
-empty the link is.
-
-This is rather circumspect and doesn't always arrive at proper
-results. For example, what is the actual link speed of an interface
-that is not really able to transmit the full 100mbit/s of data,
-perhaps because of a badly implemented driver? A PCMCIA network card
-will also never achieve 100mbit/s because of the way the bus is
-designed - again, how do we calculate the idle time?
-
-The physical link bandwidth may be ill defined in case of not-quite-real
-network devices like PPP over Ethernet or PPTP over TCP/IP. The effective
-bandwidth in that case is probably determined by the efficiency of pipes
-to userspace - which not defined.
-
-During operations, the effective idletime is measured using an
-exponential weighted moving average (EWMA), which considers recent
-packets to be exponentially more important than past ones. The Unix
-loadaverage is calculated in the same way.
-
-The calculated idle time is subtracted from the EWMA measured one,
-the resulting number is called 'avgidle'. A perfectly loaded link has
-an avgidle of zero: packets arrive exactly at the calculated
-interval.
-
-An overloaded link has a negative avgidle and if it gets too negative,
-CBQ throttles and is then 'overlimit'.
-
-Conversely, an idle link might amass a huge avgidle, which would then
-allow infinite bandwidths after a few hours of silence. To prevent
-this, avgidle is capped at
-.B maxidle.
-
-If overlimit, in theory, the CBQ could throttle itself for exactly the
-amount of time that was calculated to pass between packets, and then
-pass one packet, and throttle again. Due to timer resolution constraints,
-this may not be feasible, see the
-.B minburst
-parameter below.
-
-.SH CLASSIFICATION
-Within the one CBQ instance many classes may exist. Each of these classes
-contains another qdisc, by default
-.BR tc-pfifo (8).
-
-When enqueueing a packet, CBQ starts at the root and uses various methods to
-determine which class should receive the data. If a verdict is reached, this
-process is repeated for the recipient class which might have further
-means of classifying traffic to its children, if any.
-
-CBQ has the following methods available to classify a packet to any child
-classes.
-.TP
-(i)
-.B skb->priority class encoding.
-Can be set from userspace by an application with the
-.B SO_PRIORITY
-setsockopt.
-The
-.B skb->priority class encoding
-only applies if the skb->priority holds a major:minor handle of an existing
-class within this qdisc.
-.TP
-(ii)
-tc filters attached to the class.
-.TP
-(iii)
-The defmap of a class, as set with the
-.B split & defmap
-parameters. The defmap may contain instructions for each possible Linux packet
-priority.
-
-.P
-Each class also has a
-.B level.
-Leaf nodes, attached to the bottom of the class hierarchy, have a level of 0.
-.SH CLASSIFICATION ALGORITHM
-
-Classification is a loop, which terminates when a leaf class is found. At any
-point the loop may jump to the fallback algorithm.
-
-The loop consists of the following steps:
-.TP
-(i)
-If the packet is generated locally and has a valid classid encoded within its
-.B skb->priority,
-choose it and terminate.
-
-.TP
-(ii)
-Consult the tc filters, if any, attached to this child. If these return
-a class which is not a leaf class, restart loop from the class returned.
-If it is a leaf, choose it and terminate.
-.TP
-(iii)
-If the tc filters did not return a class, but did return a classid,
-try to find a class with that id within this qdisc.
-Check if the found class is of a lower
-.B level
-than the current class. If so, and the returned class is not a leaf node,
-restart the loop at the found class. If it is a leaf node, terminate.
-If we found an upward reference to a higher level, enter the fallback
-algorithm.
-.TP
-(iv)
-If the tc filters did not return a class, nor a valid reference to one,
-consider the minor number of the reference to be the priority. Retrieve
-a class from the defmap of this class for the priority. If this did not
-contain a class, consult the defmap of this class for the
-.B BEST_EFFORT
-class. If this is an upward reference, or no
-.B BEST_EFFORT
-class was defined,
-enter the fallback algorithm. If a valid class was found, and it is not a
-leaf node, restart the loop at this class. If it is a leaf, choose it and
-terminate. If
-neither the priority distilled from the classid, nor the
-.B BEST_EFFORT
-priority yielded a class, enter the fallback algorithm.
-.P
-The fallback algorithm resides outside of the loop and is as follows.
-.TP
-(i)
-Consult the defmap of the class at which the jump to fallback occurred. If
-the defmap contains a class for the
-.B
-priority
-of the class (which is related to the TOS field), choose this class and
-terminate.
-.TP
-(ii)
-Consult the map for a class for the
-.B BEST_EFFORT
-priority. If found, choose it, and terminate.
-.TP
-(iii)
-Choose the class at which break out to the fallback algorithm occurred. Terminate.
-.P
-The packet is enqueued to the class which was chosen when either algorithm
-terminated. It is therefore possible for a packet to be enqueued *not* at a
-leaf node, but in the middle of the hierarchy.
-
-.SH LINK SHARING ALGORITHM
-When dequeuing for sending to the network device, CBQ decides which of its
-classes will be allowed to send. It does so with a Weighted Round Robin process
-in which each class with packets gets a chance to send in turn. The WRR process
-starts by asking the highest priority classes (lowest numerically -
-highest semantically) for packets, and will continue to do so until they
-have no more data to offer, in which case the process repeats for lower
-priorities.
-
-.B CERTAINTY ENDS HERE, ANK PLEASE HELP
-
-Each class is not allowed to send at length though - they can only dequeue a
-configurable amount of data during each round.
-
-If a class is about to go overlimit, and it is not
-.B bounded
-it will try to borrow avgidle from siblings that are not
-.B isolated.
-This process is repeated from the bottom upwards. If a class is unable
-to borrow enough avgidle to send a packet, it is throttled and not asked
-for a packet for enough time for the avgidle to increase above zero.
-
-.B I REALLY NEED HELP FIGURING THIS OUT. REST OF DOCUMENT IS PRETTY CERTAIN
-.B AGAIN.
-
-.SH QDISC
-The root qdisc of a CBQ class tree has the following parameters:
-
-.TP
-parent major:minor | root
-This mandatory parameter determines the place of the CBQ instance, either at the
-.B root
-of an interface or within an existing class.
-.TP
-handle major:
-Like all other qdiscs, the CBQ can be assigned a handle. Should consist only
-of a major number, followed by a colon. Optional.
-.TP
-avpkt bytes
-For calculations, the average packet size must be known. It is silently capped
-at a minimum of 2/3 of the interface MTU. Mandatory.
-.TP
-bandwidth rate
-To determine the idle time, CBQ must know the bandwidth of your underlying
-physical interface, or parent qdisc. This is a vital parameter, more about it
-later. Mandatory.
-.TP
-cell
-The cell size determines he granularity of packet transmission time calculations. Has a sensible default.
-.TP
-mpu
-A zero sized packet may still take time to transmit. This value is the lower
-cap for packet transmission time calculations - packets smaller than this value
-are still deemed to have this size. Defaults to zero.
-.TP
-ewma log
-When CBQ needs to measure the average idle time, it does so using an
-Exponentially Weighted Moving Average which smooths out measurements into
-a moving average. The EWMA LOG determines how much smoothing occurs. Defaults
-to 5. Lower values imply greater sensitivity. Must be between 0 and 31.
-.P
-A CBQ qdisc does not shape out of its own accord. It only needs to know certain
-parameters about the underlying link. Actual shaping is done in classes.
-
-.SH CLASSES
-Classes have a host of parameters to configure their operation.
-
-.TP
-parent major:minor
-Place of this class within the hierarchy. If attached directly to a qdisc
-and not to another class, minor can be omitted. Mandatory.
-.TP
-classid major:minor
-Like qdiscs, classes can be named. The major number must be equal to the
-major number of the qdisc to which it belongs. Optional, but needed if this
-class is going to have children.
-.TP
-weight weight
-When dequeuing to the interface, classes are tried for traffic in a
-round-robin fashion. Classes with a higher configured qdisc will generally
-have more traffic to offer during each round, so it makes sense to allow
-it to dequeue more traffic. All weights under a class are normalized, so
-only the ratios matter. Defaults to the configured rate, unless the priority
-of this class is maximal, in which case it is set to 1.
-.TP
-allot bytes
-Allot specifies how many bytes a qdisc can dequeue
-during each round of the process. This parameter is weighted using the
-renormalized class weight described above.
-
-.TP
-priority priority
-In the round-robin process, classes with the lowest priority field are tried
-for packets first. Mandatory.
-
-.TP
-rate rate
-Maximum rate this class and all its children combined can send at. Mandatory.
-
-.TP
-bandwidth rate
-This is different from the bandwidth specified when creating a CBQ disc. Only
-used to determine maxidle and offtime, which are only calculated when
-specifying maxburst or minburst. Mandatory if specifying maxburst or minburst.
-
-.TP
-maxburst
-This number of packets is used to calculate maxidle so that when
-avgidle is at maxidle, this number of average packets can be burst
-before avgidle drops to 0. Set it higher to be more tolerant of
-bursts. You can't set maxidle directly, only via this parameter.
-
-.TP
-minburst
-As mentioned before, CBQ needs to throttle in case of
-overlimit. The ideal solution is to do so for exactly the calculated
-idle time, and pass 1 packet. However, Unix kernels generally have a
-hard time scheduling events shorter than 10ms, so it is better to
-throttle for a longer period, and then pass minburst packets in one
-go, and then sleep minburst times longer.
-
-The time to wait is called the offtime. Higher values of minburst lead
-to more accurate shaping in the long term, but to bigger bursts at
-millisecond timescales.
-
-.TP
-minidle
-If avgidle is below 0, we are overlimits and need to wait until
-avgidle will be big enough to send one packet. To prevent a sudden
-burst from shutting down the link for a prolonged period of time,
-avgidle is reset to minidle if it gets too low.
-
-Minidle is specified in negative microseconds, so 10 means that
-avgidle is capped at -10us.
-
-.TP
-bounded
-Signifies that this class will not borrow bandwidth from its siblings.
-.TP
-isolated
-Means that this class will not borrow bandwidth to its siblings
-
-.TP
-split major:minor & defmap bitmap[/bitmap]
-If consulting filters attached to a class did not give a verdict,
-CBQ can also classify based on the packet's priority. There are 16
-priorities available, numbered from 0 to 15.
-
-The defmap specifies which priorities this class wants to receive,
-specified as a bitmap. The Least Significant Bit corresponds to priority
-zero. The
-.B split
-parameter tells CBQ at which class the decision must be made, which should
-be a (grand)parent of the class you are adding.
-
-As an example, 'tc class add ... classid 10:1 cbq .. split 10:0 defmap c0'
-configures class 10:0 to send packets with priorities 6 and 7 to 10:1.
-
-The complimentary configuration would then
-be: 'tc class add ... classid 10:2 cbq ... split 10:0 defmap 3f'
-Which would send all packets 0, 1, 2, 3, 4 and 5 to 10:1.
-.TP
-estimator interval timeconstant
-CBQ can measure how much bandwidth each class is using, which tc filters
-can use to classify packets with. In order to determine the bandwidth
-it uses a very simple estimator that measures once every
-.B interval
-microseconds how much traffic has passed. This again is a EWMA, for which
-the time constant can be specified, also in microseconds. The
-.B time constant
-corresponds to the sluggishness of the measurement or, conversely, to the
-sensitivity of the average to short bursts. Higher values mean less
-sensitivity.

-
-When enqueueing a packet, CBQ starts at the root and uses various methods to

-
-In the absence of uncommon configuration options, the process is rather easy.
-At each node we look for an instruction, and then go to the class the
-instruction refers us to. If the class found is a barren leaf-node (without
-children), we enqueue the packet there. If it is not yet a leaf node, we do
-the whole thing over again starting from that node.
-
-The following actions are performed, in order at each node we visit, until one
-sends us to another node, or terminates the process.
-.TP
-(i)
-Consult filters attached to the class. If sent to a leafnode, we are done.
-Otherwise, restart.
-.TP
-(ii)
-Consult the defmap for the priority assigned to this packet, which depends
-on the TOS bits. Check if the referral is leafless, otherwise restart.
-.TP
-(iii)
-Ask the defmap for instructions for the 'best effort' priority. Check the
-answer for leafness, otherwise restart.
-.TP
-(iv)
-If none of the above returned with an instruction, enqueue at this node.
-.P
-This algorithm makes sure that a packet always ends up somewhere, even while
-you are busy building your configuration.

-will be generated within this qdisc.
-.TP
-allot bytes
-This allotment is the 'chunkiness' of link sharing and is used for determining packet
-transmission time tables. The qdisc allot differs slightly from the class allot discussed
-below. Optional. Defaults to a reasonable value, related to avpkt.
-.TP
-avpkt bytes
-The average size of a packet is needed for calculating maxidle, and is also used
-for making sure 'allot' has a safe value. Mandatory.

-When dequeuing to the interface, classes are tried for traffic in a
-round-robin fashion. Classes with a higher configured qdisc will generally
-have more traffic to offer during each round, so it makes sense to allow
-it to dequeue more traffic. All weights under a class are normalized, so
-only the ratios matter. Defaults to the configured rate, unless the priority
-of this class is maximal, in which case it is set to 1.
-.TP
-allot bytes
-Allot specifies how many bytes a qdisc can dequeue
-during each round of the process. This parameter is weighted using the
-renormalized class weight described above. Silently capped at a minimum of
-3/2 avpkt. Mandatory.
-
-.TP
-prio priority
-In the round-robin process, classes with the lowest priority field are tried
-for packets first. Mandatory.
-
-.TP
-avpkt
-See the QDISC section.
-
-.TP
-rate rate
-Maximum rate this class and all its children combined can send at. Mandatory.
-
-.TP
-bandwidth rate
-This is different from the bandwidth specified when creating a CBQ disc! Only
-used to determine maxidle and offtime, which are only calculated when
-specifying maxburst or minburst. Mandatory if specifying maxburst or minburst.
-
-.TP
-maxburst
-This number of packets is used to calculate maxidle so that when
-avgidle is at maxidle, this number of average packets can be burst
-before avgidle drops to 0. Set it higher to be more tolerant of
-bursts. You can't set maxidle directly, only via this parameter.
-
-.TP
-minburst
-As mentioned before, CBQ needs to throttle in case of
-overlimit. The ideal solution is to do so for exactly the calculated
-idle time, and pass 1 packet. However, Unix kernels generally have a
-hard time scheduling events shorter than 10ms, so it is better to
-throttle for a longer period, and then pass minburst packets in one
-go, and then sleep minburst times longer.
-
-The time to wait is called the offtime. Higher values of minburst lead
-to more accurate shaping in the long term, but to bigger bursts at
-millisecond timescales. Optional.
-
-.TP
-minidle
-If avgidle is below 0, we are overlimits and need to wait until
-avgidle will be big enough to send one packet. To prevent a sudden
-burst from shutting down the link for a prolonged period of time,
-avgidle is reset to minidle if it gets too low.
-
-Minidle is specified in negative microseconds, so 10 means that
-avgidle is capped at -10us. Optional.
-
-.TP
-bounded
-Signifies that this class will not borrow bandwidth from its siblings.
-.TP
-isolated
-Means that this class will not borrow bandwidth to its siblings
-
-.TP
-split major:minor & defmap bitmap[/bitmap]
-If consulting filters attached to a class did not give a verdict,
-CBQ can also classify based on the packet's priority. There are 16
-priorities available, numbered from 0 to 15.
-
-The defmap specifies which priorities this class wants to receive,
-specified as a bitmap. The Least Significant Bit corresponds to priority
-zero. The
-.B split
-parameter tells CBQ at which class the decision must be made, which should
-be a (grand)parent of the class you are adding.
-
-As an example, 'tc class add ... classid 10:1 cbq .. split 10:0 defmap c0'
-configures class 10:0 to send packets with priorities 6 and 7 to 10:1.
-
-The complimentary configuration would then
-be: 'tc class add ... classid 10:2 cbq ... split 10:0 defmap 3f'
-Which would send all packets 0, 1, 2, 3, 4 and 5 to 10:1.
-.TP
-estimator interval timeconstant
-CBQ can measure how much bandwidth each class is using, which tc filters
-can use to classify packets with. In order to determine the bandwidth
-it uses a very simple estimator that measures once every
-.B interval
-microseconds how much traffic has passed. This again is a EWMA, for which
-the time constant can be specified, also in microseconds. The
-.B time constant
-corresponds to the sluggishness of the measurement or, conversely, to the
-sensitivity of the average to short bursts. Higher values mean less
-sensitivity.
-
-.SH BUGS
-The actual bandwidth of the underlying link may not be known, for example
-in the case of PPoE or PPTP connections which in fact may send over a
-pipe, instead of over a physical device. CBQ is quite resilient to major
-errors in the configured bandwidth, probably a the cost of coarser shaping.
-
-Default kernels rely on coarse timing information for making decisions. These
-may make shaping precise in the long term, but inaccurate on second long scales.
-
-See
-.BR tc-cbq-details(8)
-for hints on how to improve this.

-.SH DESCRIPTION
-This filter allows one to match packets based on their
-.B tcindex
-field value, i.e. the combination of the DSCP and ECN fields as present in IPv4
-and IPv6 headers.
-.SH OPTIONS
-.TP
-.BI action " ACTION_SPEC"
-Apply an action from the generic actions framework on matching packets.
-.TP
-.BI classid " CLASSID"
-Push matching packets into the class identified by
-.IR CLASSID .
-.TP
-.BI hash " SIZE"
-Hash table size in entries to use. Defaults to 64.
-.TP
-.BI mask " MASK"
-An optional bitmask to binary
-.BR AND " to the packet's " tcindex
-field before use.
-.TP
-.BI shift " SHIFT"
-The number of bits to right-shift a packet's
-.B tcindex
-value before use. If a
-.B mask
-has been set, masking is done before shifting.
-.TP
-.B pass_on
-If this flag is set, failure to find a class for the resulting ID will make the
-filter fail and lead to the next filter being consulted.
-.TP
-.B fall_through
-This is the opposite of
-.B pass_on
-and the default. The filter will classify the packet even if there is no class
-present for the resulting class ID.
