WINS Windows Internet Naming Service. A system that determines the IP
address associated with a particular network computer, called name
resolution. WINS supports network client and server computers
running Windows and can provide name resolution for other
computers with special arrangements. WINS supports dynamic
addressing (DHCP) by maintaining a distributed database that is
automatically updated with the names of computers currently
available and the IP address assigned to each one.
DNS is an alternative system for name resolution suitable for network
computers with fixed IP addresses.
WLAN Wireless Local Area Network.
WM-AD WM Access Domain Services (WM-AD). Extreme Networks’ means of
mapping wireless networks to the topology of an existing wired
network. When you set up WM-AD on the Summit WM series switch,
you are defining subnets for groups of wireless users. This WM-AD
definition creates a virtual IP subnet where the Summit WM series
switch acts as a default gateway for wireless devices. This technique
enables policies and authentication to be applied to the groups of
wireless users on a WM-AD, as well as the collecting of accounting
information. When a WM-AD is set up on the Summit WM series
switch, one or more Altitude APs (by radio) are associated with it. A
range of IP addresses is set aside for the Summit WM series switch's
DHCP server to assign to wireless devices.
WMM Wi-Fi Multimedia (WMM), a Wi-Fi Alliance certified standard that
provides multimedia enhancements for Wi-Fi networks that improve
the user experience for audio, video, and voice applications. This
standard is compliant with the IEEE 802.11e Quality of Service (QoS)
extensions for 802.11 networks. WMM provides prioritized media
access by shortening the time between transmitting packets for higher
priority traffic. WMM is based on the Enhanced Distributed Channel
Access (EDCA) method.
WPA Wireless Protected Access, or Wi-Fi Protected Access is a security
solution adopted by the Wi-Fi Alliance that adds authentication to
WEPs’ basic encryption. For authentication, WPA specifies IEEE 802.1x
authentication with Extensible Authentication Protocol (EAP). For
encryption, WPA uses the Temporal Key Integrity Protocol (TKIP)
mechanism, which shares a starting key between devices, and then
changes their encryption key for every packet. Certificate
Authentication (CA) can also be used. Also part of the encryption
mechanism are 802.1X for dynamic key distribution and Message
Integrity Check (MIC) a.k.a. Michael.
WPA requires that all computers and devices have WPA software.
