Virtual Local Area Network (VLAN)
What happens if users need a virtual connection between two stations belonging to two different physical LANs? A Virtual Local Area Network (VLAN) is defined as a local area network configured by software, not by physical wiring. Virtual LANs (VLANs) have recently developed into an integral feature of switched LAN solutions from every major LAN equipment vendor. One of the reasons for the attention placed on VLAN functionality now is the rapid deployment of LAN switching that began in 1994/1995. The shift toward LAN switching as a replacement for local/departmental routers - and now even shared media devices (hubs)-will only accelerate in the future.
