Re: [SR-Users] Create new listener on the fly

Hi Casrten, Thanks for the comment. I know you provide IMS, have you contributed to Kamailio IPsec, or do you have something in-house solution for this part? (I hope this question will not be off-topic) BRHossein On Wednesday, October 26, 2022 at 06:37:33 AM PDT, Carsten Bock <carsten(a)ng-voice.com> wrote: Hi Hossein, yes, you are right, it is in-efficient. It may be fine for a private network/PoC/Lab/ or anything else small, but it will not really work for a commercial network - for that you need something different.

Kamailio uses a static pool of preforked SIP worker processes, and this is initialised once upon startup. These child processes are spawned for every listener, and communicate and share data using SysV IPC and shared memory. The shared memory pool is likewise initialised upon startup, as is the small fixed-size area of private memory associated with each other worker process (“package memory”). While perhaps not strictly impossible to alter, this setup isn’t particularly amenable to the dynamic creation and destruction of listeners, or the additional child processes they beget. The child processes need to be forked on startup, before their heap is laden with runtime baggage. All this is relatively expensive to initialise. — Alex -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ __________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussions sr-users(a)lists.kamailio.org Important: keep the mailing list in the recipients, do not reply only to the sender!
