Высокоточное тестирование для реальных сетей
Сетевой эмулятор Network Emulator II — это высокоточный тестовый инструмент для 10GE, 1GE и 100MbE Ethernet и 2/4/8/16 FibreChannel, который позволяет ИТ точно эмулировать сетевые условия, возникающие в сетях LAN / WAN в реальном времени. С помощью эмуляции сети нового поколения от Ixia организации могут проверять и тестировать производительность нового оборудования, протоколов и приложений в контролируемой лабораторной среде.
Как приложения будут выполняться при распределении между центрами обработки данных?
Каковы будут точные последствия задержки работы приложений и сети?
Как будет выполняться резервное копирование центра обработки данных в реальной среде?
Ixia Network Emulator II отвечает на все эти вопросы, чтобы определить реальную производительность сети без последствий.
Для критически важных развертываний Network Emulator II можно комбинировать с переключателями байпаса, которые позволяют быстро и легко переключаться между Network Emulator II и операционными сетями с минимальным нарушением сетевого трафика.
