Virtual Extensible LAN

<p>Virtual eXtensible LAN (VXLAN) is a <a href="/facts/Network_virtualization/aWUs94EW">network virtualization</a> technology that uses a <a href="/facts/VLAN/QhdJNaWX">VLAN</a>-like encapsulation technique to encapsulate <a href="/facts/OSI_model/oxN9Xhjz">OSI</a> <a href="/facts/Layer_2/K9yPufbt">layer 2</a> <a href="/facts/Ethernet_frame/LC4BXFhI">Ethernet frames</a> within <a href="/facts/Layer_4/UmIGUCeK">layer 4</a> <a href="/facts/User_Datagram_Protocol/dxLU0D6q">UDP</a> datagrams, using 4789 as the default <a href="/facts/IANA/b6MlP6zQ">IANA</a>-assigned destination UDP port number, although many implementations that predate the IANA assignment use port 8472. VXLAN attempts to address the <a href="/facts/Scalability/jh7JomPa">scalability</a> problems associated with large <a href="/facts/Cloud_computing/guhg0FGV">cloud computing</a> deployments.  VXLAN endpoints, which terminate VXLAN tunnels and may be either virtual or physical <a href="/facts/Switch_port/CnvmhNYT">switch ports</a>, are known as VXLAN tunnel endpoints (VTEPs).
