Gigabit to desktop? Not so fast

Vendors might be moving full-bore to drive Gigabit Ethernet to the desktop, but users have other plans - at least for now.
Hewlett-Packard this week will debut two fixed-port Gigabit Ethernet switches aimed at desktop users. Foundry Networks also this week will unveil a Gigabit workgroup box. Cisco recently announced new copper-based Gigabit switch products, and Dell has promised to ship its business PCs with integrated 10/100/1000Base-T ports.
The decision to upgrade to Gigabit seems simple, right?
Not so, according to industry observers, who say there are few applications to utilize the high-speed network gear, and technical hurdles such as PC throughput preclude widespread implementation. "The biggest obstacle I see to Gigabit on the desktop is that there's no killer app for it," says Lawrence Orans, a senior analyst with Gartner. "There's no need for a mainstream end user of a business PC to have Gigabit Ethernet on his desktop. For the daily computing tasks most enterprise end users take on - e-mail, Web browsing and some client/server applications - 10/100M bit/sec Ethernet is just fine."
While applications such as voice and video have been touted as killer applications for desktop Gigabit, this is a misconception, Orans says. An uncompressed voice call over IP takes up only 64K bit/sec of bandwidth. A quality video stream is not much higher, averaging from 200K to 400K bit/sec. "That's a drop in the bucket when you're talking about a 100-megabit connection," he says.
