Abstract: A method and apparatus for assessing network traffic loads, separating the network traffic into the traffic classes either with or without specific client priority/business input, and managing the allocation of available network resources based on the class of the traffic. Differentiated traffic classes of communication services, such as time sensitive and non-time sensitive, may be specified via a set of parameters to permit a network to provide corresponding services that result in a guaranteed amount of available network resources, such as bandwidth. The set of parameters allows the network operator to categorize each type of network traffic into traffic classes and designate a predetermined level of network resources per class, thereby achieving the QoS—Quality of Service—and predictable traffic service performance guarantee appropriate to the needs of the end users of the network in a multi-class, multi-priority network environment.
