In a flat-bridged network, a broadcast domain is confined to a single LAN segment or even a specific physical location,
such as a department or building floor. In a switch-based network, such as one comprised of Alcatel-Lucent switching
systems, a broadcast domain—or VLAN— can span multiple physical switches and can include ports from a variety of
media types. For example, a single VLAN could span three different switches located in different buildings and include
10/100 Ethernet, Gigabit Ethernet, 802.1q tagged ports and/or a link aggregate of ports.
