| 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. | ||
