【摘要】：随着互联网的快速发展,网络应用不断丰富,其中也出现了很多对服务质量有极高要求的应用,它们对带宽、时延和抖动等网络性能参数极其敏感。为了使这些应用可以达到要求的服务质量,我们必须要保证它们执行时可以获得足够的网络资源。因此,在保证安全性和保密性的情况下,研究并开发域间协作网络管理系统不仅能打破网络管理系统的自组织性、封闭性和协作方式人工化的现状,而且可以使多个管理域间合作提供多样化的、用户体验更好的服务。 从20世纪90年代,信息系统从面向数据向面向流程转变,相对于面向数据的,面向流程的信息系统面对不断变化的业务环境和不断变化的用户需求,可以快速地适应变化。业务流程管理是能够根据业务环境的变化,推进人与人之间、人与系统之间以及系统与系统之间的整合及调整的IT工具。业务流程管理可以更好地支持信息交互、信息共享和协商合作。因此,业务流程管理可以提高信息系统的性能。 本课题在现有的域间协作网络管理系统的基础上,实现了业务流程流程管理,提高了系统响应用户需求和业务环境变化的速度,完善了系统功能,提高了系统性能。本课题增加了在线人为决策,与已有的系统自动决策相互补充使用,为资源预留请求提供更加灵活的决策支持。业务流程管理可以更好地支持人工活动。 本文首先介绍域间协作网络管理系统的整体框架和各模块的功能,在此基础上,对资源预留服务的业务处理逻辑进行了深入分析并完成了业务流程建模；其次,提出了一种基于Petri网关联矩阵的模型验证方法,并使用已完成的业务流程模型作为例子,说明了此模型验证方法的使用过程,证明了此方法在实际情况下的有效性；再次,根据正确无误的业务流程模型进行了业务流程实现和业务流程部署,从而完善了域间协作网络管理系统的功能,提高了系统性能。
[Abstract]:With the rapid development of the Internet, network applications are becoming more and more abundant. Among them, there are many applications with high QoS requirements, which are extremely sensitive to network performance parameters such as bandwidth, delay and jitter. In order for these applications to achieve the required QoS, we must ensure that sufficient network resources can be obtained when they are executed. Therefore, under the condition of ensuring security and confidentiality, the research and development of inter-domain cooperative network management system can not only break the status quo of self-organization, closure and artificial cooperation mode of network management system. It also enables multiple administrative domains to collaborate to provide a diverse, user experience with better services. From the 1990s, information systems changed from data-oriented to process-oriented. Compared with data-oriented, process-oriented information systems can adapt to the changes rapidly in the face of changing business environment and changing user needs. Business process management (BPM) is a IT tool that can promote the integration and adjustment between people, systems and systems according to the change of business environment. Business process management can better support information interaction, information sharing and negotiation. Therefore, business process management can improve the performance of information systems. Based on the existing inter-domain cooperative network management system, this paper realizes business process management, improves the speed of the system responding to user needs and changes of business environment, improves the system function and improves the system performance. This paper adds online artificial decision making, complements with existing system automatic decision making, and provides more flexible decision support for resource reservation request. Business process management can better support human activities. Firstly, this paper introduces the whole framework of inter-domain cooperative network management system and the functions of each module. On this basis, the business process logic of resource reservation service is deeply analyzed and the business process modeling is completed. Secondly, a model verification method based on Petri net correlation matrix is proposed, and using the completed business process model as an example, the application process of the model verification method is illustrated, and the validity of the method in practice is proved. Thirdly, according to the correct business process model, the business process implementation and business process deployment are carried out, thus improving the function of the inter-domain cooperative network management system and improving the system performance.
