This paper addresses the types of QoS dissatisfaction caused by imbalance of the initial I/O workload pattern and storage performance across multiple storage servers in a storage cluster. It next proposes a systematic scheme to resolve the QoS problem that periodically monitors the QoS satisfaction level, analyzes the causes of the QoS problem, and performs data migration based on the analysis ...
In this paper, the authors develop a comprehensive framework for QoS management based on soft probabilistic contracts. The authors approach also encompasses general QoS parameters, with “response time” as a particular case. In addition, the authors support composite QoS parameters, for example, combining timing aspects with “quality of data” or security level. They also study contract compositi...
Standards-based quality of service (QoS)-enabled component middleware is increasingly used as a platform for networkcentric, distributed, real-time and embedded (DRE) systems where applications require ensured network QoS even when network resources are scarce or congestion is present. Traditional approaches to building network-based, QoS-sensitive applications, such as Internet telephony and s...
Currently, the interface description languages in component and web service infrastructures provide support for the description of functional properties, and structures such as deployment descriptors configure some specific non-functional aspects (e.g. persistence, security, transactions). But the infrastructures do not provide support for the description and management of general QoS (e.g. lat...
