With LAN emulation, whatever type of traffic running in existing networks -- such as Ethernet, FDDI (
Fiber Distributed Data Interface) or Token Ring -- is translated into ATM cells.
Not since the late 1980s has there been a networking standard as stable and robust as the
fiber distributed data interface (FDDI).
"In health care, in part, you're seeing
fiber distributed data interface (FDDI) networks migrating to ATM because health care has plans for not only bandwidth intensive applications but voice, video and data," she says.
Across distances up to 50 kilometers, enterprises can simultaneously utilize ATM, coupling link, enterprise system connectivity (ESCON), Ethernet, Fast Ethernet,
fiber distributed data interface (FDDI), Fibre Channel, FICON, Gigabit Ethernet, SONET, EMC symmetrix remote data facility (EMC SRDF), sysplex timer, and other high-speed, proprietary applications without impact on network performance.
When fiber optics first emerged as a data communications medium a few years back as the basis for FDDI (
Fiber Distributed Data Interface), it represented a quantum leap in bandwidth capacity over copper wiring (from 10-16 Mbps to 100 Mbps).
Xylan, of Calabasas, Calif., used Networld+ Interop to unveil a family of high-speed switches that can pass data from both Ethernet and token ring LANs over FDDI (
fiber distributed data interface) as well as ATM backbones.
Local area network (LAN) services are provided with InteLAN, which provides Ethernet and
fiber distributed data interface (FDDI) connectivity.
FDDI, or
fiber distributed data interface, technology has been around for several years, but only recently has it received much attention from users.
