Deep packet inspection systems let network managers control network traffic flows. Controlling network traffic requires limiting bandwidth to convinced applications, guaranteeing minimum bandwidth to others, and marking traffic with high or low priorities. While that process is typically called traffic management, these activities may plus be described as WAN optimization, application performance management, traffic shaping, bandwidth management, bandwidth optimization and quality of service (QoS).

There are some subtle differences among these terms. For example, traffic management uses QoS

mechanisms, such as traffic classification, prioritization, queuing and rate limiting. When used informally, however, these terms all loosely describe setting rules or policies for how specific application traffic should behave and next ensuring the network automatically enforces those rules.

Advanced traffic-management systems, which usually rely on deep packet inspection (DPI) technologies, let network managers control network traffic flows based on application types, source and destination addresses, and other variables. To supply that […]
