Virtual Extensible LAN Virtual Extensible LAN Virtual Extensible LAN (VXLAN) is a network virtualization technology that attempts to address the scalability problems associated with large cloud computing deployments. It uses a VLAN-like encapsulation technique to encapsulate OSI layer 2 Ethernet frames within layer 4 UDP datagrams, using 4789 as the default IANA-assigned destination UDP port number. VXLAN endpoints, which terminate VXLAN tunnels and may be either virtual or physical switch ports, are known as VXLAN tunnel endpoints (VTEPs). 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
Recursive acronym Recursive acronym A recursive acronym is an acronym that refers to itself. The term was first used in print in 1979 in Douglas Hofstadter's book "Gödel, Escher, Bach: An Eternal Golden Braid", in which Hofstadter invents the acronym GOD, meaning "GOD Over Djinn", to help explain infinite series, and describes it as a recursive acronym. Other references followed, however the concept was used as early as 1968 in John Brunner's science fiction novel "Stand on Zanzibar". In the story, the acronym EPT (Education for Particular Task) later morphed into "Eptification for Particular Task". Recursive acronyms typically form backwardly: either an
