WPA Wi-Fi Protected Access. It was created in response to several
serious weaknesses researchers had found in the previous
system , Wired Equivalent Privacy (WEP). WPA implements
the majority of the IEEE 802.11i standard, and was intended as
an intermediate measure to take the place of WEP while
802.11i was prepared. WPA is specifically designed to also
work with pre-WPA wireless network interface cards (through
firmware upgrades), but not necessarily with first generation
wireless access points. WPA2 implements the full standard,
but will not work with some older network cards (Wikipedia).
WPA-PSK Wi-Fi Protected Access - Pre Shared Key. WPA was designed
to enhance the security of wireless networks. There are two
types of WPA: enterprise and personal. Enterprise is meant for
use with an IEEE 802.1X authentication server, which
distributes different keys to each user. Personal WPA utilizes a
less scalable 'pre-shared key' (PSK) mode, where every
allowed computer is given the same passphrase. In PSK
mode, security depends on the strength and secrecy of the
passphrase. The design of WPA is based on a Draft 3 of the
IEEE 802.11i standard.
WPA-Radius Wi-Fi Protected Access - Radius (802.1X authentication
server). WPA was designed to enhance the security of wireless
networks. There are two flavors of WPA: enterprise and
personal. Enterprise is meant for use with an IEEE 802.1X
authentication server, which distributes different keys to each
user. Personal WPA utilizes less scalable 'pre-shared key'
(PSK) mode, where every allowed computer is given the same
passphrase. In PSK mode, security depends on the strength
and secrecy of the passphrase. The design of WPA is based
on a Draft 3 of the IEEE 802.11i standard.
WPS Wi-Fi Protected Setup. It is a standard for easy and secure
establishment of a wireless home network. The goal of the
WPS protocol is to simplify the process of connecting any
home device to the wireless network.
WRED Weighted Random Early Detection. It is an active queue
management mechanism that provides preferential treatment
of higher priority frames when traffic builds up within a queue.
A frame's DP level is used as input to WRED. A higher DP
level assigned to a frame results in a higher probability that the
frame is dropped during times of congestion.
WTR Wait To Restore. This is the time a fail on a resource has to be
'not active' before restoration back to this (previously failing)
resource.
