Traffic Management (QoS)
Contemporary users demand more from wireless connections—more band-
width and more multimedia applications—but they also demand less jitter and
fewer dropped calls.
The ProCurve Wireless Edge Services xl Module helps RPs to deliver a high
QoS for voice, video, and other high-priority or time-sensitive traffic.
The Wireless Edge Services xl Module and adopted RPs support protocols
designed to improve QoS over the radio medium:
SpectraLink Voice Priority (SVP)
Wireless Multimedia (WMM)
In addition, the Wireless Edge Services xl Module can use voice prioritization
to mark traffic destined to VoWLAN devices for priority handling in both the
Ethernet and wireless network.
Using WLAN prioritization and weighted fair queuing (WFQ), the Wireless
Edge Services xl Module queues traffic outbound to RPs according to the
WLAN to which it is destined. The module allocates relatively more bandwidth
to the queues for WLANs with a higher priority.
Figure 4-52 displays where these various QoS mechanisms affect traffic.
