Abstract: Considering specific operational and corporate service requirements, this article proposes an approach for providing quality of service (QoS) in multiservice networks based on the IP (Internet Protocol) technology. The basic elements of the proposed approach encompass DiffServ- aware QoS architecture, proposal for traffic classification, proposal for configuration of the data plane QoS implementation mechanisms, as well as the model of QoS control and management. Particularly, the proposed approach is applicable to private networks with specific operational and corporate needs (power utilities, traffic and transport, etc.), which mandatory require different levels of QoS in order to assure stable and reliable system operation.
Keywords: Internet protocol, quality of service, service differentiation, policing, scheduling, queue management, QoS control, QoS management.
