.. _shaper:
[shaper]
========
Accel-ppp support many ways customisation rate-limit. Also limiting clients bandwidths sometimes called as QoS (Quality of Service), but QoS has more possibilities. For enable rate-liniter, we can sets ``shaper`` in section ``[modules]``.
Config overview
---------------
**attr=name**
By default: ``attr=Filter-Id``.
Specifies which radius attribute contains rate information. RADIUS server can transmit ``Filter-Id=1000``, means 1000Kbit both up-stream and down-stream rate or ``Filter-Id=2000/3000``, means 2000Kbit down-stream rate and 3000Kbit up-stream rate.
**attr-up=name**
By default is not defined.
Specifies which radius attribute contains rate information for **upstream**. Often used if needs separate *upstream* and *downstream* attributes.
**attr-down=name**
By default is not defined.
Specifies which radius attribute contains rate information for **downstream**. Often used if needs separate *upstream* and *downstream* attributes.
**vendor=name**
By default is not defined.
Specifies vendor name for support attributes of other vendors like *Cisco-AVPair* or *Mikrotik*.
Example for Cisco:
.. code-block:: sh
vendor=Cisco
attr=Cisco-AVPair
Example for Mikrotik:
.. code-block:: sh
vendor=Mikrotik
attr=Mikrotik-Rate-Limit
**burst-factor=n**
By default is not defined.
Burst will be calculated as rate multiply burst-factor. Common ``burst-factor`` for upstream calculated as ``burst-factor*10``.
**up-burst-factor=n**
By default is ``up-burst-factor=1``
Specifies burst factor for **upstream**.
**down-burst-factor=n**
By default is ``down-burst-factor=0.1``
Specifies burst factor for **downstream**.
**cburst=n**
By default is ``cburst=1534``
Specifies amount of bytes that can be burst at 'infinite' speed. Recommendation: cburst should be equal to at most one average packet
**latency=n**
By default is ``latency=0.05``
Specifies latency (in milliseconds) parameter of tbf qdisc which set maximum amount of time a packet can sit in the TBF.
**mpu=n**
By default is ``mpu=0``
Specifies mpu parameter in bytes of tbf qdisc and policer. Determines the minimal token usage for a packet.
**r2q=n**
By default is ``r2q=10``
Specifies r2q parameter of root htb qdisc.
**quantum=n**
By default is ``quantum=1500``
Specifies quantum parameter of htb classes. Amount of bytes a flow is allowed to dequeue before the scheduler moves to the next class.
**moderate-quantum=1|0**
By default is disabled ``moderate-quantum=0``
If fixed quantum is not specified and this option is specified then shaper module will check for quantum value is valid (in range 1000-200000).
**fwmark=n**
By default is disabled: ``fwmark=0``
Specifies the fwmark for traffic that won't be passed through shaper.
**up-limiter=police|htb**
By default is: ``up-limiter=police``
Specifes upstream rate limiting method.
**down-limiter=tbf|htb**
By default is: ``down-limiter=tbf``
Specifies downstream rate limiting method.
**ifb=ifb_ifname**
By default ``ifb=ifb0``
Specifies name of ifb interface, used only for ``up-limiter=htb``
**leaf-qdisc=qdisc parameters**
By default is not defined.
In case if htb is used as up-limiter or down-limiter specified leaf qdisc can be attached automaticaly. At present *sfq* and *fq_codel qdiscs* are implemented. *CoDel* (the name comes from "controlled delay") is Active Queue Manager. Parameters are same as for tc:
``sfq [limit NUMBER] [perturb SECS] [quantum BYTES]``
``fq_codel [limit PACKETS] [flows NUMBER] [target TIME] [interval TIME] [quantum BYTES] [[no]ecn]``
**rate-multiplier=n**
By default is ``rate-multiplier=1``
Due to accel-ppp operates with rates in kilobit basis if you send rates in different basis then you can use this option to bring your values to kilobits. For ``vendor=Mikrotik`` often sets ``rate-multiplier=0.001``
**rate-limit=downstream/upstream**
By default is not defined.
Specifies default speed if there are no radius attributes.
**time-range=range_id,time_start-time_end**
By default is not defined.
Specifies time ranges for automatic rate reconfiguration. You can specify multiple such options.
Configuration example:
.. code-block:: none
[shaper]
time-range=1,1:00-3:00
time-range=2,3:00-5:00
time-range=3,5:00-7:00
The first number is time range identifier. To define a specific rates uses following format of radius attributes: range-id,rate, range-id,down-rate/up-rate or cisco-like.
As an example:
.. code-block:: none
Filter-Id=1000
Filter-Id=1,2000
Filter-Id=2,3000
Filter-Id=3,4000
That means: set 1000Kbit by default, set 2000Kbit in time range 1, set 3000Kbit in time range 2 and set 4000Kbit in time range 3.
You have to pass multiple Filter-Id attributes to utilize this functionality.
