ey. 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 (Wikipedia)

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.
