The emerging deployment of large-scale cloud applications incurs significant inter-datacenter traffic, which makes the scarce wide-area bandwidth across data centers become the performance bottleneck. To achieve the desirable network performance, bandwidth guarantee should be provided for the resulting inter-datacenter traffic. However, the existing bandwidth allocation methods mainly focus on ...

Chromatic scheduling polytopes arise as solution sets of the bandwidth allocation problem in certain radio access networks supplying wireless access to voice/data communication networks to customers with individual communication demands. This bandwidth allocation problem is a special chromatic scheduling problem; both problems are N P-complete and, furthermore, there exist no polynomial-time al...

Efficient dynamic resource provisioning algorithms are necessary to the development and automation of Quality of Service (QoS) networks. The main goal of these algorithms is to offer services that satisfy the QoS requirements of individual users while guaranteeing at the same time an efficient utilization of network resources. In this thesis we introduce a new service model that provides per-fl...

Multibeam satellite networks can extend the service coverage as deploying its spot beam. It is important to allocate the appropriate resources to downlink multibeams to prevent the unnecessary waste of resources in the satellite system. This paper presents an optimum beam allocation scheme for multi-spot beam satellite system, as beam bandwidth to be allocated is controlled dynamically. We appl...

In this paper, genetic algorithm (GA) is proposed for the design of an optimization algorithm to achieve the bandwidth allocation of ATM network. In Broadband ISDN, the ATM is a highbandwidth; fast packet switching and multiplexing technique. Using ATM it can be flexibly reconfigure the network and reassign the bandwidth to meet the requirements of all types of services. By dynamically routing ...

The paper presents a novel approach for Dynamic Bandwidth Allocation (DBA) in GEO Satellite Networks based on adaptive predictive control. In the proposed DBA scheme each Satellite Gateway (SG) uses an adaptive predictor to forecast the future input traffic flow along with a bandwidth controller to generate a bandwidth request to the Bandwidth Manager (BM) according to a receding-horizon policy...

This research is focused on enhanced best-effort service, which provides the minimum bandwidth guarantee and distributes the available bandwidth fairly to packet flows in a high speed network. These goals can be reached when the bandwidth allocation is general weighted (GW) fair among the flows. GW fairness ensures the minimum rate for every flow and, furthermore, allocates the excess bandwidth...

Next generation high-speed cellular networks are expected to support multimedia applications, which require QoS provisions. Since frequency spectrum is the most expensive resource in wireless networks, it is a challenge to support QoS using limited frequency spectrum. In the literature, two orthogonal approaches are used to address the bandwidth utilization issue and the QoS provision issue; th...

A detailed understanding of the many facets of the Internet’s topological structure is critical for evaluating the performance of networking protocols, for assessing the effectiveness of proposed techniques to protect the network from nefarious intrusions and attacks, or for developing improved designs for resource provisioning. In this way Available bandwidth estimation is a vital component of...

Due to the limited bandwidth in wireless networks, careful resource allocation schemes must be used to allocate bandwidth to applications. There are two typical types of applications in wireless networks that require resource allocation: soft realtime applications and best effort applications. While soft realtime applications require QoS support for effective bandwidth utilization, best effort ...
