1 | Traffic Shaper For Linux | ||
2 | |||
3 | This is the current BETA release of the traffic shaper for Linux. It works | ||
4 | within the following limits: | ||
5 | |||
6 | o Minimum shaping speed is currently about 9600 baud (it can only | ||
7 | shape down to 1 byte per clock tick) | ||
8 | |||
9 | o Maximum is about 256K, it will go above this but get a bit blocky. | ||
10 | |||
11 | o If you ifconfig the master device that a shaper is attached to down | ||
12 | then your machine will follow. | ||
13 | |||
14 | o The shaper must be a module. | ||
15 | |||
16 | |||
17 | Setup: | ||
18 | |||
19 | A shaper device is configured using the shapeconfig program. | ||
20 | Typically you will do something like this | ||
21 | |||
22 | shapecfg attach shaper0 eth1 | ||
23 | shapecfg speed shaper0 64000 | ||
24 | ifconfig shaper0 myhost netmask 255.255.255.240 broadcast 1.2.3.4.255 up | ||
25 | route add -net some.network netmask a.b.c.d dev shaper0 | ||
26 | |||
27 | The shaper should have the same IP address as the device it is attached to | ||
28 | for normal use. | ||
29 | |||
30 | Gotchas: | ||
31 | |||
32 | The shaper shapes transmitted traffic. It's rather impossible to | ||
33 | shape received traffic except at the end (or a router) transmitting it. | ||
34 | |||
35 | Gated/routed/rwhod/mrouted all see the shaper as an additional device | ||
36 | and will treat it as such unless patched. Note that for mrouted you can run | ||
37 | mrouted tunnels via a traffic shaper to control bandwidth usage. | ||
38 | |||
39 | The shaper is device/route based. This makes it very easy to use | ||
40 | with any setup BUT less flexible. You may need to use iproute2 to set up | ||
41 | multiple route tables to get the flexibility. | ||
42 | |||
43 | There is no "borrowing" or "sharing" scheme. This is a simple | ||
44 | traffic limiter. We implement Van Jacobson and Sally Floyd's CBQ | ||
45 | architecture into Linux 2.2. This is the preferred solution. Shaper is | ||
46 | for simple or back compatible setups. | ||

3022 | The traffic shaper is a virtual network device that allows you to | ||
3023 | limit the rate of outgoing data flow over some other network device. | ||
3024 | The traffic that you want to slow down can then be routed through | ||
3025 | these virtual devices. See | ||
3026 | <file:Documentation/networking/shaper.txt> for more information. | ||

13 | * warranty for any of this software. This material is provided | ||
14 | * "AS-IS" and at no charge. | ||
15 | * | ||
16 | * | ||
17 | * Algorithm: | ||
18 | * | ||
19 | * Queue Frame: | ||
20 | * Compute time length of frame at regulated speed | ||
21 | * Add frame to queue at appropriate point | ||
22 | * Adjust time length computation for followup frames | ||
23 | * Any frame that falls outside of its boundaries is freed | ||
24 | * | ||
25 | * We work to the following constants | ||
26 | * | ||
27 | * SHAPER_QLEN Maximum queued frames | ||
28 | * SHAPER_LATENCY Bounding latency on a frame. Leaving this latency | ||
29 | * window drops the frame. This stops us queueing | ||
30 | * frames for a long time and confusing a remote | ||
31 | * host. | ||
32 | * SHAPER_MAXSLIP Maximum time a priority frame may jump forward. | ||
33 | * That bounds the penalty we will inflict on low | ||
34 | * priority traffic. | ||
35 | * SHAPER_BURST Time range we call "now" in order to reduce | ||
36 | * system load. The more we make this the burstier | ||
37 | * the behaviour, the better local performance you | ||
38 | * get through packet clustering on routers and the | ||
39 | * worse the remote end gets to judge rtts. | ||
40 | * | ||
41 | * This is designed to handle lower speed links ( < 200K/second or so). We | ||
42 | * run off a 100-150Hz base clock typically. This gives us a resolution at | ||
43 | * 200Kbit/second of about 2Kbit or 256 bytes. Above that our timer | ||
44 | * resolution may start to cause much more burstiness in the traffic. We | ||
45 | * could avoid a lot of that by calling kick_shaper() at the end of the | ||
46 | * tied device transmissions. If you run above about 100K second you | ||
47 | * may need to tune the supposed speed rate for the right values. | ||
48 | * | ||
49 | * BUGS: | ||
50 | * Downing the interface under the shaper before the shaper | ||
51 | * will render your machine defunct. Don't for now shape over | ||
52 | * PPP or SLIP therefore! | ||
53 | * This will be fixed in BETA4 | ||
54 | * | ||
55 | * Update History : | ||
56 | * | ||
57 | * bh_atomic() SMP races fixes and rewritten the locking code to | ||
58 | * be SMP safe and irq-mask friendly. | ||
59 | * NOTE: we can't use start_bh_atomic() in kick_shaper() | ||
60 | * because it's going to be recalled from an irq handler, | ||
61 | * and synchronize_bh() is a nono if called from irq context. | ||
