Hello, you can find more details about that in the module documentation:
“Using this algorithm, you can also enable congestion control by setting the attribute 'cc=1', when 'cc' is enabled the 'weight' attribute will also be used to control congestion tolerance. When facing congestion the weight of a gateway is lowered by 1 for every ms of estimated congestion, a 'rweight' value of 50 is recommended. See the example "configuring load balancing with congestion detection" below.“ https://kamailio.org/docs/modules/5.6.x/modules/dispatcher.html#dispatcher.f.ds_select_dst Cheers, Henning -- Henning Westerholt – https://skalatan.de/blog/ Kamailio services – https://gilawa.com<https://gilawa.com/> From: satyaprakash ch <[email protected]> Sent: Monday, November 14, 2022 9:17 AM To: Henning Westerholt <[email protected]> Cc: Kamailio (SER) - Users Mailing List <[email protected]> Subject: Re: [SR-Users] Uneven-distribution of calls Hi, But we are having 2 setups in which 1st setup - we are having 3 freeswitch. 2nd setup - we are having 4 freeswitch. with the same dispatcher configuration as the above chain mail. However, we are getting an issue of uneven distribution of calls in only 2nd setup. and 1st setup is working fine. Note: can you explain to me some brief on congestion control (cc=1). Thanks and Regards, Satyaprakash. On Mon, Nov 14, 2022 at 1:07 PM Henning Westerholt <[email protected]<mailto:[email protected]>> wrote: Hello, The 5.4.x branch has reached its end of life. You could try to update to the latest version 5.4.9, or even better, do an update to a newer version of the 5.5.x or 5.6.x branch. It could be also an effect of the congestion control (cc=1). You could try to deactivate it.

We have 2 proxies and 4 freeswitches where the calls from the 2 proxies will be distributed to 4 freeswitches with the dispatcher module. The dispatcher module parameters are as follows: #--- Dispatcher params ---- modparam("dispatcher", "db_url", DBURL_LOCAL) modparam("dispatcher", "flags", 2) modparam("dispatcher", "xavp_dst", "ds_dst") modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_ping_interval", 30) modparam("dispatcher", "ds_ping_from", "sip:proxy@VAR_LOCAL_IP") The weight based distributions are given in database as follows: rweight=50;weight=50;cc=1; Let me know the details which you need from me. Thanks and regards, Satyaprakash.

The dispatcher lists are having the same weight. For example: If we are having 4 freeswitches, the calls are evenly distributing for 3 freeswitches but there is high calls for the 4th freeswitch. The dispatcher weight for the freeswitches are: rweight=50;weight=50;cc=1; Thanks and regards, Satya
