Re: [OpenSIPS-Users] Ratelimit usage

2023-10-27 Thread Adrien LACOMME

I tried with SBT and it is way better, gonna stay with this one for CPS.

I did my tests by trying RED and TAILDROP algorithm, wasn't probably the good 
one to try for cps and with my type of traffic.

Thanks for your response and your time

Adrien

Have you read the description of the RED algorithm? Are you sure you are 
generating appropriate traffic to cause a drop? That algorithm seems like it 
would be difficult to control/predict the drops accurately for a test. If you 
are sending a constant traffic volume to it, it never will drop.



If you are just testing, you may want to go with a simpler algorithm where you 
can more easily control when/how many are being dropped.



The standard way to use the module for CPS is to use the SBT algorithm with a 
window_size of 1. [1]

Hello,



I added this line to my code, in fact it's better to decrease the counter if I 
drop the call.

But my problem is that the rl_check function never drop calls, I do not enter 
in the IF condition.



For the algorithm, I'm actually just trying the module, I will probably not 
stay with RED.

Hello Adrien

Try :

if (!rl_check("test1", 1, "RED"))

{

   rl_dec_count("test1")

   send_reply(487, "Request Terminated: CPS limit exceeded");

   exit;

}

* If you are using ratelimit to limit only successful traffic, you need to 
explicitely decrease the counter for the declined calls using the 
rl_dec_count() function
also I’m not sure RED is the best algorithm for your usecase.

Hi,



I'm trying to implement CPS limitation on OpenSIPS and I got some difficulties 
to understand how ratelimit module works.



Here is the setup (I want to limit cps to 1) :



if (!rl_check("test1", 1, "RED")) {

  send_reply(487, "Request Terminated: CPS limit exceeded");

}



I tried to make few calls simultaneously but rl_check return is always FALSE.



Here is the log I got :



2023-10-27T16:52:19.792337 SBC /usr/sbin/opensips[137782]:

Shouldn't the module block calls when the counter goes to 2 ? Or is he checking 
the load value to block ? If yes, why the load value isn't incremented ?

Re: [OpenSIPS-Users] I need some help in attr matching while forming the Branch .

2023-10-27 Thread Ben Newlin

Just wanted to add that with the solution I recommended below, you would want 
to make sure you properly handle the case where all branches were dropped 
because none matched. The proper handling in that case for your system would be 
defined by your requirements.

Without seeing the specific exact code, I can’t say what is causing that error. 
It seems like it may be a syntax issue. For example, in your email you are 
missing the semicolon after the line setting the count. I don’t know if it is 
that way in your config script. I recommend double checking all your syntax, 
and if you still get the error please provide the exact code from your script 
for review.

For #2, I can’t really be very specific there because I don’t know all of your 
logic, nor am I very knowledgeable about the registrar module. My first thought 
is to not do any filtering/checking in the request route. Just allow the 
registrar module to load all contacts in branches, but arm a branch_route. Then 
perform the check in the branch route for each branch. If the Contact for the 
branch doesn’t match what you want, you can drop the branch [1].

Ahhh , Ok .
Now it's very  complicated . When you said a loop that's looping in my mind . 
Sorry for the bad joke .

In case , the number of elements in each Invite won't be fixed . So the number 
of loops will vary from one Invite to another .
I was thinking of counting the number of elements first , then as the index 
starts from 0 I will loop till count-1 to fetch every element properly .

Example :
$var(count) = $(hdr(Call-Info){csv.count})## if the number is 3 then loop 
will be for 3 times starting from 0 to 2

 $var(i) = 0;
while($var(i) < $var(count) )
{
xlog("counter: $var(i)\n");
$var(i) = $var(i) + 1;
}

This was my initial thought . But while finding the count it gave me an error . 
 $var(count) = $(hdr(Call-Info){csv.count})  Is this not in the correct format ?

parse error in /usr/local/etc/opensips/opensips-p2p.cfg:267:26-55: unknown 
script variable

As I have earlier mentioned my header will look like .
Call-Info: sales,en,level20,en (this can be anything but format will be like 
this . )  . How do I count the number of values ?

2. As I am doing this matching to filter out contacts, where should I do this ? 
If I am doing this while giving a call to the contacts , for the 1st 
transaction it is doing the comparison , after that for the next branch it 
processes the call without matching . Which is not right . For every contact 
this comparison should loop
