XLNT Designs announced its new Millennium 4000 Gigabit Ethernet switch that ties Ethernet-based networks to Fiber Distributed Data Interface (FDDI) connections. The five-slot Millennium chassis, which will ship in the third quarter, supports 10, 100, and 1,000 mbps Ethernet. The company will demonstrate the new switch at Spring Networld+Interop '97 in Las Vegas next month.
