A CONCEPTUAL MODEL OF QUALITY OF SERVICE MECHANISMS IN PACKET-SWITCHED NETWORKS
Abstract
The paper presents analysis and generalization of the quality of service mechanisms in packetswitched networks. Decomposition of the quality of service mechanisms is presented. Each QoS control mechanism can be split into four components. Each component is responsible for the defined subtask. A method of formalization is offered in which each QoS mechanism component is presented by function of defined arguments. Presented method is used for simulation of QoS mechanisms in the next generation networks.
