Тестирование производительности L2/L3 инфраструктуры.
IxNetwork обеспечивает тестирование производительности сети с широким диапазоном условий. Способен генерировать несколько терабайт данных и одновременно анализировать до 4 миллионов ip потоков одновременно, IxNetwork способен масштабироваться для тестирования самых мощных устройств и крупнейших сетей. Благодаря расширенному анализу и статистике в реальном времени это решение эмулирует все: от маршрутизации и коммутации, ЦОД на Ethernet и SDN до широкополосного доступа и промышленного Ethernet для всестороннего тестирования. Графический интерфейс (GUI) лёгкий и удобный, делает возможным производительное выполнение широкого круга задач.
Основные преимущества решения:
- Сохранение капитальных затрат в тестировании — эмуляция очень большого количества маршрутизаторов и коммутаторов без использования реальных устройств
- Сокращение времени тестирования — используется визуальный, основанный на топологии способ конфигурации
- Проблемы определяются уже в лабах, до развёртывания их на местах — реалистичная иммитация реальных условий с гранулированной настройкой трафика
- Понимание производительности и узких мест — даёт возможность развивать сеть основываясь на реальной производительности оборудования
