VLAN's, or virutal local area networks, appear at the application level or Level 7 o the OSI model. VLAN's use tagging or pot+tagging to route traffic to and from a specific area (like a specific departement in a business). VLAN technology relies on ethernet connectivity throughout the network it functions on (a more ubiquitious medium than standard trunking and TCIP, etc).

VLAN's require an edge switch to tag the outgoing traffic and recieve the incomming traffic and allows you to prioritize traffic (tagged v/s untagged) so you can provide services like ip telephony, video sessions, SIP, etc.
