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.
