Service Class Commands
Introduction
Service levels provide a means of defining service flows with specific QoS parameters (such as maximum, minimum, or reserved traffic rates, priority, and service scheduling types) and binding them to a named service class. The concept of maximum assigned bandwidth, in the context of a service class, provides a means for controlling the amount of bandwidth that a particular service class can use on an interface. This allows a user to configure levels of service to support applications with specific bandwidth and priority requirements such as voice, video, and data and to further permit users to provide differentiated levels of service.
Admission control is an authorization mechanism that provides a method of controlling the admission of service flows belonging to specific service classes on individual interfaces. Admission control is determined by the bandwidth percentage (maximum assigned bandwidth) and the amount of
The creation of service classes involves assigning service flows to a service class and providing all flows belonging to that class with a defined Quality of Service. DOCSIS
