一种网络服务自动部署方法

An automatic approach to Web services allocation

为满足网络服务使用者对网络服务部署的功能性和非功能性需求,运用Petri网的方法进行了互联网动态多变环境下的网络服务自动部署的研究,建立了一种基于Petri网的网络服务部署网模型,从形式化的角度描述了网络服务功能的部署情况,提出了一种按照服务质量来选择最优网络服务部署的算法。仿真的结果表明,与目前常用的固定部署算法和随机部署算法相比,按照该方法得到的网络服务部署能最好地满足服务使用者对服务的非功能性方面的需求。

To meet the functional and non-functional requirements of Web service users for Web services allocation, the on automatic allocation for Web services under a dynamic and heterogeneous Intemet environment was performed study by a Petri net-based approach. A Web service configuration net based on Petri nets was built in order to exhibit web service functional configuration in a formal way. The simulation results prove that the method can best satisfy Web service users＇ non-functional requirements compared with commonly used fixed and random allocation algorithms.
