To improve the Quality of Service (QoS) ability of TNPOSS (To Next-hop Port Sequence Switch) network, this paper proposes a QoS-enhanced TNPOSS (QTNPOSS) network model by introducing Fractal Leak Bucket (FLB) shaper and Weighted Fair Queuing (WFQ) scheduler. In the proposed model, packets of multimedia traffic are shaped by the FLB shaper and scheduled by the WFQ scheduler. Moreover, the service curve and the Maximum E2E delay of QTNPOSS network are given by using the mathematical tool of the network calculus. Numerical analysis shows that both the long-range dependence (LRD) property of multimedia traffic and the WFQ weight have influences on the maximum E2E delay, and the WFQ weight influences the maximum E2E delay more greatly than the LRD property does.
