QoS Implementation
Implementing QoS covers these categories: classification and marking of traffic, choosing a queuing method, conditioning traffic (shaping and policing), and efficiently using bandwidth. The following section deals with these categories, and examines how these components are implemented in a network.
Classification and Marking of QoS
Classification is the process of grouping traffic based on its QoS needs. Two methods are used to break up traffic into classes: access control lists (ACLs) and network-based application recognition (NBAR).
