28.1 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
ZyWALL. This maximizes SIP traffic throughput for improved VoIP call sound quality.
