ITU-T Y.3120 (01/2023)

Функциональная архитектура для обеспечения гарантированного времени задержки в крупномасштабных сетях, включая сети IMT-2020 и дальнейших поколений

В Рекомендации МСЭ-T Y.3120 определены функциональная архитектура, функциональные объекты, контрольные точки и рабочие процедуры, относящиеся к требованиям и структуре, которые определены в Рекомендации МСЭ-T Y.3113, на основе архитектуры, которая определена в Рекомендации МСЭ-T Y.2111. Наряду с этим в Рекомендации МСЭ-T Y.3113 определено использование планирования на основе агрегации потоков (FA) и контроллеров на границах домена агрегации (AD). В Рекомендации МСЭ-T Y.2111 определены функции управления ресурсами и допуском (RACF) для обеспечения сквозного качества обслуживания (QoS) и необходимые транспортные функции в сетях последующих поколений (СПП).
