This article describes how Traffic shaping allows you to regulate the network traffic flow to assure a certain level of quality of service (QoS). 

Instructions

Quality of Service is applied using 4 mechanisms.

• Link Definition: Tells the traffic shaper which WAN link the packet is using. In a site with multiple links, each link has its own bandwidth limits and is managed independently.
• Application Classifiers: Identifies and determines which protocol or application class traffic belongs to.
• Service Classes: Maps applications to acceleration decisions, traffic filters, and traffic-shaping policies.
• Traffic Shaping Policies: Tells the traffic shaper weighted priority and bandwidth limits to assign to which traffic type (application classifier).
