communicate with each other.
Simple Network Management Protocol (SNMP)
SNMP is an Internet‐standard protocol for managing devices on IP networks.
Snooping
Passively watching a network for data that can be used to benefit a hacker, such as passwords.
Temporal Key Integrity Protocol (TKIP)
An encryption protocol that uses 128‐bit keys that are dynamically generated and distributed by the authentication server. TKIP regularly changes and rotates the encryption keys so that the same encryption key is never used twice.
Transmission Control Protocol/Internet Protocol (TCP/IP)
A protocol permitting communications over and between networks. The TCP/IP protocol is the basis for Internet communications.
Weighted Fair Queuing (WFQ)
WFQ services queues based on their priority and queue weight. Queues with larger weights get more service than queues with smaller weights. This queuing mechanism is highly efficient in that it divides any available bandwidth across the different traffic queues. See also Queuing Algorithms.
Wired Equivalent Privacy (WEP)
A security protocol that provides a WLAN with a level of security and privacy comparable to what is usually expected of a wired LAN. WEP encrypts data transmitted between wired and WLANs to keep the transmission private.
Wireless Local‐Area Network (WLAN)
WLANs use RF technology to transmit and receive data wirelessly in a certain area. This allows users in a small zone to transmit data and share resources, such as printers, without physically connecting each computer with cables.
Wi‐Fi Protected Access (WPA )
A subset of the IEEE 802.11i standard. WPA applies IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless clients using an external RADIUS database. WPA encrypts data by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. See also WPA‐PSK (WPA ‐Pre‐Shared Key).
Wi‐Fi MultiMedia (WMM)
Part of the IEEE 802.11e QoS enhancement to the Wi‐Fi standard that ensures quality of service for multimedia applications in WLANs.
Wireless Client Supplicants
A wireless client supplicant is the software that runs on an operating system instructing the wireless client how to use WPA.
WPA ‐Pre‐Shared Key (WPA‐PSK)
WPA‐PSK requires a single (identical) password entered into each access point, wireless gateway and wireless client. As long as the passwords match, a client will be granted access to a WLAN. See also WPA.
