Hi,
I have a question regarding LCR module and their weight variable.
If I have 4 gateways for the same prefix, and with the same priority:
Rule_id
Gw_id
Priority
weight
36
68
1
60
36
69
1
14

70

13

71

13
The weight variable acts as a percentage of utility

The weight variable acts as a percentage of utility of that gateway?
If for example I have 100 calls, the gateway with gw_id 68 will receive 60
calls , and the other 14, 13 and 13?
check README. it used to explain how weight is interpreted.

Hello
On kamailio 1.5.2, I need to choose the gw from a group according to its
weight. After trying unsuccessfully with different values I realized that the
help guide says that the load_gw functions can return gateways according to
gateway's randomized weight within its
group. So, I
Fabian Borot writes:
1- since it is randomized, does this mean that the weight parameter
actually can not guarantee that the weight value can decide how
gateways are ordered?
it is a randomized weight, not an absolute priority.
2- once I have the gws on the avp, is it posible to re-order
Thanks Juha, I figured that the avp reordering would be something like that.
The help file for versions 3.1 and 3.2 also says randomized weight, does it
really work on those versions?
this is from 3.2

When the function load_gws() is called, matching gateways (that

yes it does.
or do you mean the priority column on the lcr_rule_target table
instead?
yes.
This may be a dumb question but since I don't get it I have to ask:
thank you Juha, I understand the purpose and that is how I intend to use it,
[more weights for gws with more capacity]
but I guess I should have rephrase my question as: what is the purpose of the
randomized weight value then? when you randomize it then the weight parameter
becomes useless.

3 gws inside same group, and assuming the higher the weight the higher
the capacity

I would like to send more calls to gw 3, then gw 2 then gw 1
but if when I do a load_gws, and I randomize the weight
just to mention that kamctl base depends on awk, so this language can
be used in case something is easier to do with it than pure shell.

ricardo,
i studied the weight problem a bit more and came to the conclusion that
implementing a fair weighting algorithm would be too complicated.
below is a script that can be used to find weight values matching
desired probabilities for lcr gateways. i don't know if it would be

As you can see there is no a 20,20,20,20,10,10 call repartition.
Could this be a bug?
ricardo,
it is a feature of the way randomized weights are currently
calculated. if you have two wgs with weights 1 and 2 and then generate
two random numbers
1 * random number

my email client does not know to display your data, but weight is
