unicast packet A single data message (packet) sent to a specific IP address.
W
WDS Wireless Domain Services. An access point providing WDS on your wireless
LAN maintains a cache of credentials for CCKM-capable client devices on your
wireless LAN. When a CCKM-capable client roams from one access point to
another, the WDS access point forwards the client's credentials to the new access
point with the multicast key. Only two packets pass between the client and the
new access point, greatly shortening the reassociation time.
WEP Wired Equivalent Privacy. An optional security mechanism defined within the
802.11 standard designed to make the link integrity of wireless devices equal to
that of a cable.
WLSE Wireless LAN Solutions Engine. The WLSE is a specialized appliance for
managing Cisco Aironet wireless LAN infrastructures. It centrally identifies and
configures access points in customer-defined groups and reports on throughput
and client associations. WLSE's centralized management capabilities are further
enhanced with an integrated template-based configuration tool for added
configuration ease and improved productivity.
WNM Wireless Network Manager.
workstation A computing device with an installed client adapter.
WPA Wi-Fi Protected Access is a standards-based, interoperable security enhancement
that strongly increases the level of data protection and access control for existing
and future wireless LAN systems. It is derived from and will be
forward-compatible with the upcoming IEEE 802.11i standard. WPA leverages
TKIP (Temporal Key Integrity Protocol) for data protection and 802.1X for
authenticated key management.
