чительно более эффективным его использование, в особенности использование стандарта Gigabit Ethernet в ранге магистральных сетей. Главное отличие контроля качества QoS на основе RSVP от QoS, реализованного в технологии ATM, заключается в том, что RSVP рассчитан на работу в дейтаграммных сетях и не требует наличия виртуальных каналов. Потенциально сегодня ATM предоставляет более разнообразные возможности по QoS по сравнению с другими сетевыми технологиями. Однако на практике возможности манипуляции функцией QoS, одной из блестящих черт ATM, в рамках конкретных приложений очень скудны, и не предвидится существенный прогресс в этой области. Очерчены предварительные спецификации будущего стандарта 10G Ethernet (скорость передачи 10 Гбит/с), начало поставок оборудования планируется в 2001 году [41]. Таким образом, стандарт Ethernet c масштабируемой иерархией 10/100/1000/... становится мощной сетевой технологией, жестко конкурирующей с ATM как на уровне корпоративных, так и магистральных сетей.
