Virtual Extensible LAN
Virtual Extensible LAN (VXLAN) is a network virtualization technology that attempts to ameliorate the scalability problems associated with large cloud computing deployments. It uses a VLAN-like encapsulation technique to encapsulate MAC-based OSI layer 2 Ethernet frames within layer 4 UDP packets.
VXLAN is an evolution of efforts to standardize on an overlay encapsulation protocol. It increases scalability up to 16 million logical networks and allows for layer 2 adjacency across IP networks. Multicast is used to contain broadcast, multicast and unknown unicast traffic.
The VXLAN specification was originally created by VMware, Arista Networks and Cisco. Other backers of the VXLAN technology include Broadcom, Citrix, Pica8, Cumulus Networks, Dell, Mellanox, OpenBSD and Red Hat.
Open vSwitch supports VXLAN overlay networks.
