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
The Centre for Computing History from programming workshops using 1980s BBC Micros to gaming tours to coding using software like Scratch for the Raspberry Pi. The centre also loans artefacts for film and TV productions and has helped with props and sets for "The IT Crowd", "Brits Who Made the Modern World" on Channel Five with Peter Snow and in April 2009 produced the "Gadget Hall of Fame" stand at "The Gadget Show Live" exhibition at the NEC in Birmingham. The centre collects and preserves historical computing related artefacts and has undertaken a project to preserve the data from the BBC Domesday Project and make
