DDS中一种面向方案的QoS管理模型

A plan-oriented QoS management model in DDS

为为了满足基于DDS(Distributed Data Service)的实时系统对非功能特征的需求,很多研究者都对QoS(Quality of Service)进行了大量的研究,但是目前对可复用、可验证、可优化、可配置的QoS管理技术研究不足。针对基于DDS的实时系统中QoS的管理问题,本文提出了面向方案的QoS管理模型,同时为了提高QoS管理模型的逻辑推理和自适应能力,本文给出了QoS管理模型的本体表示。应用结果表明,该模型能够极大的降低开发实时分布式系统的复杂性,提高QoS的可复用能力,优化对QoS的管理能力。

In order to meet DDS (Distributed Data Service)-based real-time systems’ requirements for non-function properties, many researchers have studied QoS (Quality of Service) widely and deeply, but there is still rarely QoS management technology, which is reusable, verifiable, optimizable, and configurable. Aiming at solving the QoS management problems in DDS-based real-time systems, this paper proposed a plan-oriented QoS management model. Meanwhile, to increase its logic reasoning and self-adaptation abilities, the semantic ontology of the QoS management model is introduced. After applying the management model, it shows that the management model is able to largely reduce the complexities of developing real-time distributed systems, increase the reusability of QoS, and optimize the management of QoS.
