19. Конфигурация Line-rate
• Пропускная способность может падать до 75% скорости на портах,
когда размер пакетов <200 Байт
• Конфигурация Line-rate с помощью CLI может быть использована
для гарантирования пропускной способности при всех размерах
пакетов (для избежания sawtooth drop пакетов, когда размер пакетов
<200 Байт)
• 12 портов (из 16-ти) в каждом Pipeline могут быть назначены с Linerate и будут иметь приоритет над oversubscribe портами.
• На стек портах можно сконфигурировать Line-rate, чтобы иметь
гарантированный контрольный трафик стекирования.
19

20. Latency
• Задержка изменена до значения ниже 600 наносекунд для port-toport latency с использованием Cut-through конфигурации
Cut-through
• ASIC Trident2 имеет возможность Cut-through, которая отличается от
предыдущих чипов и может использоваться для улучшения
задержки. Режим Cut-through обходит управление доступом, очереди
и планирование. В отличии от предыдущих реализаций
использующих Alternative Store и Forward, Trident2 Cut-through не
требует буферизации любой части пакета. Поддержка Cut-through
возможна для 40G портов в режимах oversubscribe или line-rate.
Поддержка Cut-through для 10G портов возможна только в режиме
Line-rate.
