Performances assessment of the scheduling mechanism for the management of the quality service (QoS) in the IP network

To make the networks services flexible with the guarantee of parameters performance (time, gigue, flow and rate of loss of packages), it necessarily must, on the one hand, integrate a concept of priority using the mechanisms of scheduling, management and control in the network, and on the other hand to ensure a total quality of service. The quality of service (QoS) can be based on the architecture DiffServ (Differentiated Services) which offers a differentiation by priority based on a classification of packages at the entry of the network and a differentiated treatment inside. The management of the quality of service from beginning to end implies the presence of specific mechanisms of quality management.
