1. Абонента А – Opensips – Media2 – Абонент B (600)
Тестирование проводится командой sipp. Необходимо поправит скрипт, для того, чтобы sipp работал c opensips. Заставить работать ту версию, что поставке – никак не смог.
/sipp -default_behaviors abortunexp -s 600 -sf uac_pcap.xml sip.fiberpipe.in -r 10 -trace_err
Первая Проблема была традиционной: ограничение на кол-во открытых файлов в системе.
Вторая проблема касалась того, что Mysql для таких систем должен стоять либо в памяти либо на SSD.
Третья проблема касалась ограничения кол-ва поключений к Mysql.
Вытекающие проблемы: надо делать для Mysql репликацию из памяти на HDD.
После решения первых трех проблем кол-во вызовов в системе возразло , критическую нагрузку нет возможность поверить не позволили возможности абонента А. Дошли до 300.
