Introduction
ProCurve Wireless Edge Services zl Module
The Wireless Edge Services zl Module manages wireless traffic with several
QoS mechanisms, ensuring that each type of traffic receives the necessary
level of service. The module supports the following QoS protocols, which you
can enable on a WLAN-to-WLAN basis:
■ SpectraLink Voice Priority (SVP)
■ priority queuing based on WMM or on a WLAN classification
These protocols improve QoS in the wireless network. You can also configure
the module to mark traffic outbound to voice stations for high priority. Called
Voice prioritization, this feature improves the QoS for traffic destined to
wireless stations, as the traffic travels through both the Ethernet network and
the wireless network.
Finally, the Wireless Edge Services zl Module can implement weighted fair
queueing (WFQ) on traffic destined from the module to RPs.
Figure 1-16 illustrates which traffic is affected by each QoS mechanism.
