Refined QoS assessment based on application differentiation
Jian Wei Gong · Journal of PLA University of Science and Technology · 2011
To meet the diversified demands for QoS of new network applications,a refined QoS assessment based on application differentiation(RQoSAAD) was proposed.The QoS achievement ratio and the degree of traffic satisfaction of different applications and internetworking in a measurement period was computed respectively by analyzing the performance metrics,and the QoS achievement ratio,the degree of satisfaction of different applications,the internetworking and users' holistic traffic and the QoS level in a large time scale were further deduced using Simpson's rule so as to thoroughly distinguish the QoS of different users.RQoSAAD was implemented in NBOS,a prototype system of a latemodel network management system in CERNET.The detailed QoS report provided by RQoSAAD in NBOS enables users and operators to understand network QoS from different aspects and facilitates the processes of network status evaluation,configuration update,feedback control and adjustment.
