There i s an increasing demand for Internet core nodes to have (I) quality-of-service (QoS) guarantees and (2) higher switching capacity. The combined input and output queued (CiOQ) switching has been shown to be a promising solution to meet such demand. However, many of the proposed scheduling algorithms fo r a CIOQ switch cannot be practically implemented due to problems from scalability and ...

This paper introduces a scheme for online dynamic bandwidth allocation for variable bit rate (VBR) traffic over ATM networks. The presented method determines the optimum bandwidth renegotiation time and bandwidth amount to allocate to VBR traffic source by minimizing predefined cost functions. Traffic rate predictor designed by wavelets is provided as feedback to the system. The results show th...

Multicast routing uses a structure, either a tree or a mesh, to connect the receivers to the source, thus saving the bandwidth. How to share the cost among the receivers in a certain fair way has been studied widely in literature. When the agents, either the links or the nodes, in the network are selfish, it is desirable to pay the agents in a proper way such that each agent still reveals its t...

We consider the problem of traffic allocation in multipath IP networks. We postulate that the desired equilibrium distribution of network bandwidth is one where every flow acquires a TCP-fair share along each of the routes connecting its ingress and egress. This characterization calls for connection striping at the ingress to balance the load among the available routes. Still, the desired equil...

It is expected that the proportional fair (PF) scheduler will be used widely in cdma2000 1xEV-DO systems because it maximizes the sum of each user’s utility, which is given by the logarithm of its average throughput. In this paper, we address an influence of the PF scheduler on the packet transmission delay in base station (BS) and propose an analytic model.

We consider a queue fed by a mixture of light-tailed and heavytailed traffic. The two traffic classes are served in accordance with the Generalized Processor Sharing (GPS) discipline. GPS-based scheduling algorithms, such as Weighted Fair Queueing (WFQ), have emerged as an important mechanism for achieving service differentiation in integrated networks. We derive the asymptotic workload behavio...

Assured Service has been proposed within the Differentiated Services (DiffServ) model to provide relative service differentiation by attempting to allocate bandwidth to different users in a controlled way during periods of network congestion. In this paper, we analyze the Assured Service scheme by means of a priority queueing system with statedependent service scheduling based on thresholds. We...

In the current politico-economic context made unstable by the coming up of several different conflicts, it is interesting to deal with the use and the development of models. Indeed, it is necessary to pay special attention to projections obtained with current models because parameters are often estimated with data which no longer reflect the economic context they have to describe. Moreover, a m...
