Firewall is a network security system used for preventing unauthorized ac-
cess to or from a private network.
Fully Qualified Domain Name. FQDN is a complete domain name that identi-
fies a computer or host on the Internet.
Fully Qualified Location Name. FQLN is a device location identifier in the
format: APname.Floor.Building.Campus.
Use of radio frequency spectrum as regulated by governments.
Free Space Path Loss. FSPL refers to the loss in signal strength of an elec-
tromagnetic wave that would result from a line-of-sight path through free
space (usually air), with no obstacles nearby to cause reflection or diffraction.
File Transfer Protocol. A standard network protocol used for transferring files
between a client and server on a computer network.
Generic Attribute Registration Protocol. GVRP is a LAN protocol that allows
the network nodes to register and de-register attributes, such as network
addresses, with each other.
Generic Advertisement Service. GAS is a request-response protocol, which
provides Layer 2 transport mechanism between a wireless client and a server
in the network prior to authentication. It helps in determining a wireless net-
work infrastructure before associating clients, and allows clients to send que-
ries to multiple 802.11 networks in parallel.
Gateway is a network node that allows traffic to flow in and out of the net-
work.
Gigabits per second.
Gigabytes per second.
GET refers HTTP request method or an SNMP operation method. The GET
HTTP request method submits data to be processed to a specified resource.
The GET SNMP operation method obtains information from the Management
Information Base (MIB).
Gigahertz.
Greenwich Mean Time. GMT refers to the mean solar time at the Royal Ob-
servatory in Greenwich, London. GMT is the same as Coordinated Universal
Time (UTC) standard, written as an offset of UTC +/- 00:00.
Goodput is the application level throughput that refers to the ratio of the total
bytes transmitted or received in the network to the total air time required for
transmitting or receiving the bytes.
Global Positioning System. A satellite-based global navigation system.
Generic Routing Encapsulation. GRE is an IP encapsulation protocol that is
used to transport packets over a network.
Generic Token Card. GTC is a protocol that can be used as an alternative to
MSCHAPv2 protocol. GTC allows authentication to various authentication
databases even in cases where MSCHAPv2 is not supported by the data-
base.
GARP VLAN Registration Protocol or Generic VLAN Registration Protocol.
GARP is an IEEE 802.1Q-compliant protocol that facilitates VLAN registra-
tion and controls VLANs within a larger network.
