Application Patrol
19.1 Overview
Application patrol provides a convenient way to manage the use of various
applications on the network. It manages general protocols (for example, HTTP and
FTP) and instant messenger (IM), peer-to-peer (P2P), Voice over IP (VoIP), and
streaming (RSTP) applications. You can even control the use of a particular
application’s individual features (like text messaging, voice, video conferencing,
and file transfers). Application patrol also has powerful bandwidth management
including traffic prioritization to enhance the performance of delay-sensitive
applications like voice and video.
There is also an option that gives SIP traffic priority over all other traffic going
through the NXC. This maximizes SIP traffic throughput for improved VoIP call
sound quality.
19.1.1 What You Can Do in this Chapter
• The General summary screen (
) enables and disables
application patrol.
• The Common, Instant Messenger, Peer to Peer, VoIP, and Streaming
screens (
) display the applications the NXC can
recognize, and review the settings for each one. You can also enable and disable
the rules for each application and specify the default and custom policies for
each application.
• The Application Patrol Edit screen (
) edits the
settings for an application.
• The Application Policy Edit screen (
) edits a group
of settings for an application.
• The Other screens (see
) control what the NXC does
when it does not recognize the application, and it identifies the conditions that
refine this. It also lets you open the Other Configuration Add/Edit screen to
create new conditions or edit existing ones.
