Abstract:

Differentiated queuing service ( DQS) is a QoS ( Quality of Service) model that can efficiently provide QoS for wired and wireless integrated networks. In this paper,based on the service discipline of DQS,the arriving flows with the same delay requirement are taken as an FBM ( Fractional Brownian Motion) traffic,and then the DQS models with multi-class FBM traffic and with the corresponding delay requirements are established. Moreover,the formula of the packet loss is deduced according to the proposed models. It is shown that the simulated results of the proposed models are consistent with those obtained based on the packet size. Besides,the analytical results of the model performances also demonstrate that the burstiness of real-time traffic greatly affects the QoS guarantee of DQS.

Key words: integrated network, quality of service, differentiated queuing service, fractional Brownian motion
