Traffic Shaper For Linux
|
||||
|
||||
This is the current BETA release of the traffic shaper for Linux. It works
|
||||
within the following limits:
|
||||
|
||||
o Minimum shaping speed is currently about 9600 baud (it can only
|
||||
shape down to 1 byte per clock tick)
|
||||
|
||||
o Maximum is about 256K, it will go above this but get a bit blocky.
|
||||
|
||||
o If you ifconfig the master device that a shaper is attached to down
|
||||
then your machine will follow.
|
||||
|
||||
o The shaper must be a module.
|
||||
|
||||
|
||||
Setup:
|
||||
|
||||
A shaper device is configured using the shapeconfig program.
|
||||
Typically you will do something like this
|
||||
|
||||
shapecfg attach shaper0 eth1
|
||||
shapecfg speed shaper0 64000
|
||||
ifconfig shaper0 myhost netmask 255.255.255.240 broadcast 1.2.3.4.255 up
|
||||
route add -net some.network netmask a.b.c.d dev shaper0
|
||||
|
||||
The shaper should have the same IP address as the device it is attached to
|
||||
for normal use.
|
||||
|
||||
Gotchas:
|
||||
|
||||
The shaper shapes transmitted traffic. It's rather impossible to
|
||||
shape received traffic except at the end (or a router) transmitting it.
|
||||
|
||||
Gated/routed/rwhod/mrouted all see the shaper as an additional device
|
||||
and will treat it as such unless patched. Note that for mrouted you can run
|
||||
mrouted tunnels via a traffic shaper to control bandwidth usage.
|
||||
|
||||
The shaper is device/route based. This makes it very easy to use
|
||||
with any setup BUT less flexible. You may need to use iproute2 to set up
|
||||
multiple route tables to get the flexibility.
|
||||
|
||||
There is no "borrowing" or "sharing" scheme. This is a simple
|
||||
traffic limiter. We implement Van Jacobson and Sally Floyd's CBQ
|
||||
architecture into Linux 2.2. This is the preferred solution. Shaper is
|
||||
for simple or back compatible setups.

The traffic shaper is a virtual network device that allows you to
|
||||
limit the rate of outgoing data flow over some other network device.
|
||||
The traffic that you want to slow down can then be routed through
|
||||
these virtual devices. See
|
||||
<file:Documentation/networking/shaper.txt> for more information.
|

|

*
|
||||
*
|
||||
* Algorithm:
|
||||
*
|
||||
* Queue Frame:
|
||||
* Compute time length of frame at regulated speed
|
||||
* Add frame to queue at appropriate point
|
||||
* Adjust time length computation for followup frames
|
||||
* Any frame that falls outside of its boundaries is freed
|
||||
*
|
||||
* We work to the following constants
|
||||
*
|
||||
* SHAPER_QLEN Maximum queued frames
|
||||
* SHAPER_LATENCY Bounding latency on a frame. Leaving this latency
|
||||
* window drops the frame. This stops us queueing
|
||||
* frames for a long time and confusing a remote
|
||||
* host.
|
||||
* SHAPER_MAXSLIP Maximum time a priority frame may jump forward.
|
||||
* That bounds the penalty we will inflict on low
|
||||
* priority traffic.
|
||||
* SHAPER_BURST Time range we call "now" in order to reduce
|
||||
* system load. The more we make this the burstier
|
||||
* the behaviour, the better local performance you
|
||||
* get through packet clustering on routers and the
|
||||
* worse the remote end gets to judge rtts.
|
||||
*
|
||||
* This is designed to handle lower speed links ( < 200K/second or so). We
|
||||
* run off a 100-150Hz base clock typically. This gives us a resolution at
|
||||
* 200Kbit/second of about 2Kbit or 256 bytes. Above that our timer
|
||||
* resolution may start to cause much more burstiness in the traffic. We
|
||||
* could avoid a lot of that by calling kick_shaper() at the end of the
|
||||
* tied device transmissions. If you run above about 100K second you
|
||||
* may need to tune the supposed speed rate for the right values.
|
||||
*
|
||||
* BUGS:
|
||||
* Downing the interface under the shaper before the shaper
|
||||
* will render your machine defunct. Don't for now shape over
|
||||
* PPP or SLIP therefore!
|
||||
* This will be fixed in BETA4
|
||||
*
|
||||
* Update History :
|
||||
*
|
||||
* bh_atomic() SMP races fixes and rewritten the locking code to
|
||||
* be SMP safe and irq-mask friendly.
|
||||
* NOTE: we can't use start_bh_atomic() in kick_shaper()
|
||||
* because it's going to be recalled from an irq handler,
|
||||
* and synchronize_bh() is a nono if called from irq context.
