Introduction
ProCurve Wireless Edge Services xl Module
Voice Prioritization. Voice prioritization improves QoS for traffic destined
to VoWLAN devices. When you enable this feature in a WLAN, RPs monitor
frames received from stations in that WLAN. When a voice frame is detected,
the Wireless Edge Services xl Module marks all traffic destined to the source
of that frame for priority handling.
Both Ethernet devices between the module and the RP and the RP itself place
return traffic to the voice device in a high-priority queue. Thus voice prioriti-
zation can improve QoS for voice traffic in both the Ethernet and the wireless
networks.
WFQ. The Wireless Edge Services xl Module queues traffic outbound to RPs
according to the RP and the WLAN to which it is destined. Each different
WLAN on each different RP has its own queue.
The module implements WFQ to determine when to transmit traffic in these
queues. The higher the weight of the WLAN associated with the queue, the
more often the module forwards traffic in that queue.
To ensure that the most important and most latency-sensitive traffic receives
a high QoS, you weigh the associated WLAN more heavily. For example, you
could assign the default weight to a WLAN that provides users with courtesy
Internet access, a higher weight to a WLAN reserved for sales representatives,
and the highest weight of all to a WLAN with VoWLAN devices.
Licensing
ProCurve Networking grants each Wireless Edge Services xl Module (J9001A)
a license to adopt and manage a specific number of RPs. When you purchase
a module, it always includes a nonremovable license that authorizes it to adopt
up to 12 RPs.
Note Because an RP can include two built-in radios, the Wireless Edge Services xl
Module can manage up to twice as many radios as it can adopt RPs.
If you connect a thirteenth RP to the wireless services-enabled switch, the
module does not adopt it. It can, however, adopt the RP if you disconnect one
of the others: the module does not bind a license to a particular set of RPs.
For the same reason, you can move the module to a different switch, and it
continues functioning as before. Now it simply adopts the RPs that connect
to that switch. (Modules also retain licenses if you move them to a different
slot in the same switch.)
