Дисциплины обслуживания вызовов
Поступающие потоки сообщений могут обслуживаться без потерь и с
потерями. В первом случае для передачи каждого сообщения немедленно
представляется требуемое соединение, а вот втором – часть сообщений
получает отказ в обслуживании, или обслуживание их задерживается на
некоторое время.
Обслуживание с явными потерями предполагает, что сообщение и
соответствующий ему вызов при получении отказа в немедленном соединении
полностью теряются и на обслуживание больше не поступают.
Обслуживание с условными потерями предполагает, что большинство вызовов
получает немедленное обслуживание, а другие обслуживаются с задержкой
сверх допустимого срока.
Обслуживание с условными потерями может быть организовано по системе с
ожиданием соединения и с повторными вызовами.
На практике целесообразно использовать обслуживание с потерями для
систем с коммутацией каналов (рис. 1).

Рассмотрим систему с N ресурсами (соединительных линий, каналов).
Измерим время, в течение которого все ресурсы заняты, и отнесем к
рассматриваемому периоду. Это может быть числом минут (или секунд) в
данном часе, когда заняты все линии. Эта доля дает оценку вероятности
того, что все N ресурсов заняты, которая и является вероятностью потерь
по времени или вероятностью блокировки системы –

В качестве другой возможной меры перегрузки подсчитаем общее число
вызовов, поступающих в течение достаточно длительного промежутка
времени, и отметим те из них, которые оказались потерянными из-за
нехватки ресурсов. Вызовы теряются, если в момент его поступления все N
исходящих каналов оказались занятыми. Отношение числа потерянных вызовов
к их общему числу, поступивших в течение времени наблюдения, дает оценку
вероятности потерь

Пропускная способность системы
Под пропускной способностью коммутационной системы понимается
интенсивность обслуженной коммутационной системой нагрузки при заданном
качестве обслуживания в рассматриваемый промежуток времени, т.е.
вероятности потерь вызовов в системе с явными потерями.
Пропускная способность системы зависит от:
· свойств поступающего потока вызовов;
· закона распределения времени обслуживания;
· структуры, емкости коммутационной системы;
· дисциплины обслуживания;
· нормы качества обслуживания.
Простейшая модель обслуживания
Рассмотрим модель обслуживания, показанную на рис. 3.
