16 TRAFFIC CLASSES
The IEEE 802.11e standard defines eight traffic classes. Most mission-critical access points
support this standard. Traffic classes are becoming more and more important, especially on
account of wireless VoIP.
7signal Sapphire Enterprise supports the 802.11e standard. Active tests can be configured to
have a traffic class. All Sapphire versions support assignment of traffic classes, but if the
Sapphire license does not include traffic classes, Sapphire will treat the traffic as ordinary
traffic (Non-QoS, best-effort). Traffic classes are taken into account in only those networks
whose access points support this feature. A request for a traffic class does not guarantee that
it is granted. When viewing measurement reports, you might see that several traffic classes
have been used. The class granted will never exceed that requested.
The following figure describes the traffic classes for the parameters of active tests:
