Acterna DA-380

The Acterna DA-380, also known as the Domino GB Internetwork Analyzer, is a portable Gigabit Ethernet protocol analyzer engineered for real-time troubleshooting and performance validation of high-speed backbone networks. It combines full line-rate packet capture with intelligent traffic generation and multi-segment analysis capabilities to isolate and resolve internetwork problems across complex routing and switching infrastructures.
