In this paper, we design a framework that is composed of feedback signals and the corresponding source adaptation scheme to provide both differentiated bandwidth service and differentiated delay service for elastic and inelastic applications. The feedback signals consist of controlling signals and charging signals. Since the number of congested links is not limited to 1, continuous auxiliary control...
While the demand for mobile broadband wireless services continues to increase, radio resources remain scarce. Even with the substantial increase in the supported bandwidth in next generation Broadband Wireless Access Systems (BWASs), it is expected that these systems will severely suffer from congestion due to the rapid increase in demand of bandwidth intensive applications. Without efficient bandwidth...
We have previously proposed the use of dynamically priced network services to provide QoS guarantees within a network. End-to-end QoS can be achieved by concatenating several of these services from different ISPs. In this paper we consider the problem of a single ISP determining the optimal paths on which to route each service within its network, as well as the optimal bandwidth to allocate to each...
In this paper we propose a packet scheduling scheme for ensuring bandwidth as a quality of service (QoS) requirement and optimizing revenue of the network service provider. A closed form formula for updating the weights of a packet scheduler is derived from a revenue-based optimization problem. The weight updating procedure is fast and independent on the assumption of the connections' statistical...
