Telecommunications, computing, and internetworking technologies often have an enormous amount of jargon associated with them. This jargon makes it possible to speak precisely and quickly to others who are in-the-know, but can also drastically increase the learning curve for newcomers. We offer this page as a quick reference guide for common terms, acronyms, and other abbreviations that NYC Mesh technical teams use on a regular basis.
Antenna : Antenna, router and radio are often confused- see our FAQ
AP : a wifi Access Point
ARIN : American Registry for Internet Numbers- where you get your ASN
Backhaul : very high bandwidth connections, usually point to point.
BGP : This is the routing protocol of the Internet. We use it extensively to mesh our network and to connect at an IXP
BMX6 : An ad-hoc mesh protocol we use. (BatMan eXperimental 6)
BuB : “Bottom up Broadband” The beneficiaries of the networks actively participate in the planning, deployment and maintenance tasks.
Captive portal : a web page that is shown before connecting to the Internet normally
Cjdns : Caleb James DeLisle's Network Suite. Encrypted IPv6 mesh protocol.
Clearnet : the regular internet as opposed to the hidden web (Tor, I2P, Freenet)
Commons : The commons include public libraries, the Internet, parks and roads and some mesh networks. Guifi has a “Wireless Commons License”.
CPE : Customer premises equipment (e.g. a LiteBeam, NanoStation, home router). ISP jargon
