IEEE
Institute of Electrical and Electronics Engineers. This American organization was founded in 1963 and sets
standards for computers and communications.
IETF
Internet Engineering Task Force. An organization responsible for providing engineering solutions for TCP/
IP networks. In the network management area, this group is responsible for the development of the SNMP
protocol.
IKE
Internet Key Exchange. An automated method for exchanging and managing encryption keys between two

Infrastructure Mode
An 802.11 networking framework in which devices communicate with each other by first going through an
Access Point (AP). In infrastructure mode, wireless devices can communicate with each other or can
communicate with a wired network. When one AP is connected to wired network and a set of wireless
stations it is referred to as a Basic Service Set (BSS). An Extended Service Set (ESS) is a set of two or more
BSSs that form a single subnetwork. Most corporate wireless LANs operate in infrastructure mode because
they require access to the wired LAN in order to use services such as file servers or printers.
Internet Control Message Protocol
ICMP is an extension to the Internet Protocol (IP) that supports packets containing error, control, and
informational messages. The PING command, for example, uses ICMP to test an Internet connection.
