Wireless domain services (WDS) is introduced with the Cisco Structured
Wireless-Aware Network. WDS is a collection of Cisco IOS Software features that
enhance WLAN client mobility and simplify WLAN deployment and management. WDS
includes aggregation of Air/RF measurements
.
All
access points in a subnet detect and securely register, through IEEE 802.1x,
with the WDS. The WDS aggregates client and access points RF measurements for
RF managed services such as rogue AP detection, interference detection
(demonstrated by the 2.4 GHz phone in Figure
), and assisted
site surveys. The currently supported WDS feature set includes fast secure
roaming and IEEE 802.1x local authentication. Additional WDS feature sets are
planned for future software releases.
Fast secure roaming allows
authenticated client devices to roam securely from one AP to another without
any perceptible delay during reassociation
. Fast
secure roaming supports latency-sensitive applications such as wireless voice
over IP (VoIP), enterprise resource planning (ERP), or Citrix-based solutions,
without dropping connections during roaming. WDS provides fast, secure handoff
services to access points for <150ms roaming within a subnet. Cisco fast
secure roaming requires Cisco or Cisco Compatible client devices that support
the Cisco Centralized Key Management (CCKM) protocol.
