Multimedia applications often fail to perform as designed, when resources must be timeshared between multiple applications at run-time. To address this problem, a software architecture is investigated in which a centralized Dynamic Quality of Service Manager (DQM) mediates resource usage between the operating system and the applications. Applications are written to be able to execute at a range...

Disk quota systems exist to protect a limited resource and ensure that users can share it. However, existing quota management systems concentrate on controlling user privileges, rather than protecting resources. This paper suggests a new management model based upon a holistic view of resources and their controls. By acting upon a resource globally rather than upon individual users, the new appr...

Traditional static resource analyses estimate the total resource usage of a program, without executing it. In this paper we present a novel resource analysis whose aim is instead the static profiling of accumulated cost, i.e., to discover, for selected parts of the program, an estimate or bound of the resource usage accumulated in each of those parts. Traditional resource analyses are parametri...

Cloud service providers (CSPs) often overbook their resources with user applications despite maintaining service-level agreements with their customers. Overbooking is attractive to CSPs because it helps to reduce power consumption in the data center by packing more user jobs in less number of resources while improving their profits. Overbooking becomes feasible because user applications tend to...

This paper is motivated by the concern of a multi-service network provider who plans to offer quality of service guarantees to users. A bandwidth broker acts as the resource manager for each network provider. Neighboring bandwidth brokers communicate with each other to establish inter-domain resource reservation agreements. Conventional approaches for resource allocation rely on pre-determined ...

The recent growth in demand for modern applications combined with the shift to the Cloud computing paradigm have led to the establishment of large-scale cloud data centers. The increasing size of these infrastructures represents a major challenge in terms of monitoring and management of the system resources. Available solutions typically consider every Virtual Machine (VM) as a black box each w...

Energy usage of large-scale data centers has become a major concern for cloud providers. There has been an active effort in techniques for the minimization of the energy consumed in the data centers. However, most approaches lack the analysis and application of real cloud backend traces. In existing approaches, the variation of cloud workloads and its effect on the performance of the solutions ...

Usage Control policies have been introduced to overcome issues related to the usage of resources. Indeed, a Usage Control policy takes into account attributes of subjects and resources which change over time. Hence, the policy is continuously enforced while an action is performed on a resource, and it is re-evaluated at every context change. This permits to revoke the access to a resource as so...
