Introduction
ProCurve Wireless Edge Services zl Module
Figure 1-16 illustrates which traffic is affected by each QoS mechanism.

This chapter will discuss these features at a high level; to learn how to configure
them, see Chapter 4: “Wireless Local Area Networks (WLANs).”
SVP
SVP maintains a high QoS in the wireless network, specifically for VoWLAN devices
that are SVP-capable. SVP is implemented in wireless phone handsets, wireless APs,
and SpectraLink servers. This IEEE 802.11-compliant mechanism minimizes latency
for voice traffic by providing priority queues reserved for voice packets and by
increasing the probability that all voice packets are transmitted in a predictable and
timely manner.
If your network includes a SpectraLink server and SVP-capable phones, you should
enable SVP in the WLAN that includes these phones. RPs then recognize
SVP-encapsulated frames and handle them accordingly.
