| 摘要: |
| 随着SOA 技术在大规模分布式系统中的广泛应用,基于服务的软件系统(service-based software system,简称SBS)已成为软件工程领域关注的热点.为了处理服务动态性给SBS 带来的影响,基于服务的自适应软件系统(adaptive service-based software system,简称ASBS)通过对系统的监测以及动态调整,为SBS 扩展了自适应能力,从而保证系统QoS 等方面的需求得到满足.从ASBS 的性能角度出发,定义了ASBS 的结构描述,并提出了基于反射Petri 网的ASBS 性能分析模型,介绍了性能模型的构建方法以及模型的分析方法,对ASBS 性能分析进行了探索. |

| Abstract: |
| With the widespread adoption of SOA in large-scaled distributed systems, Service-Based Software system has brought much attention in the field of software engineering. Capable of monitoring system status and dynamically adjusting accordingly, Adaptive Service-Based Software system enhances SBS with self-adaptive ability to satisfy the system requirements in aspects of QoS, etc. This paper defines the structural description of ASBS, proposes a performance evaluation model based on reflective Petri net, and introduces the constructing and analyzing approaches for the performance model, which also incorporates explorations in ASBS performance analysis. |
