150 Viewing Status on the Wireless Array
Application Control Windows
The Application Control feature provides real-time visibility of application usage
by users across the wireless network. Network usage has changed enormously in
the last few years, with the increase in smartphone and tablet usage stressing
networks. Increasing traffic from legitimate business needs such as cloud- and
web-based applications, streaming media and VoIP must be handled with an
adequate quality of experience.
Application Control is discussed in the following topics:
 About Application Control — an overview of this feature.
 Application Control — displays information about applications running
on the wireless network.
 Stations (Application Control) — displays a list of stations. Click one to
analyze application control information for only that station.
About Application Control
The Array uses Deep Packet Inspection (DPI) to determine what applications are
being used and by whom, and how much bandwidth they are consuming. These
applications are rated by their degree of risk and productiveness. Filters may then
be put in place to implement per-application policies that keep network usage
focused on productive uses:
 Usage of non-productive and risky applications like BitTorrent can be
restricted using Filters.
 Traffic for mission-critical applications like VoIP and WebEx may be given
higher priority (QoS).
 Non- critical traffic from applications like YouTube may be given lower
priority (QoS).
