Control policies

Политики управляют всей логикой

1

Что хочется получить

  • Для всех пользователей проверять скорость из радиуса и выставлять соответвующую скорость
    • Скорость пользователя в биллинге произвольна и нет заранее предопределенных тарифов
  • Если радиус не ответил (тайм-аут) то для пользователей из разрешенного диапазона адресов разрешать доступ в интернет (без ограничения скорости)
  • Если радиус ответил Reject то для разрешенного диапазона разрешать работу а для запрещенного диапазона - делать редирект

Определить диапазона адресов

"Нормальные" платящие абоненты

Три диапазона (в примере только два)

  • "Старый" пул адресов 192.168.128.0/20
  • Новый пул адресов, на который только планируется миграция 100.64.128.0/20
  • Реальные адреса заменены на сеть 100.127.252.0/22

Диапазон "неплатильщиков"

Абонентам у которых образовалась задолженность, выдаются адреса из диапазона 10.3.0.0/16
