The fourth best-selling switch brand in 2013, according to NPD, is D-Link, which accounted for 6.9 percent of the total units shipped. Fountain Valley, Calif.-based D-Link, which sells networking gear into the enterprise, consumer and service provider markets, bolstered its switch portfolio last month with the launch of its latest-generation SmartPro switches for small- to midsize businesses. Called the DGS-1510 Series, the line-up includes 16-, 24, or 48-port models. D-Link said all three models have 10 Gigabit port connectivity and are ideal for SMB core deployments. The switches are stackable, and any model in the DGS-1510 series can be mixed in a single stack to allow for simultaneous configuration and management, according to D-Link. The switches also come with D-Link's Green 3.0 technology, meaning they automatically decrease power intake when traffic levels are low.
