The Virtualization Model Research Of Network Services Management

In recent years.computer network has been rapidly developing and penetrating to every field of the whole social. People are increasingly dependent on the network and demanding more network applications. A variety of network services continue to gush and user has high demand for these services. Network service providers must meet the needs of users, by providing high-quality, managed network services to improve competitiveness. In recent years, network services management has become a hot topic within the field of network management at home and abroad.Because virtualization middleware and other new technologies are emerging, network services are diversity、hierarchical. Cloud computing as a new computing model combining with grid computing、virtualization technology, distributed technology. Web services and SOA thinking features, supports for "everything is service". Moreover, network service management needs, the quality assessment parameters as well as meet the user’s quality of service requirements are not the same in the management of network services. Therefore, with this new network environment and management needs, the development of the traditional network service management system is facing enormous challenges. The traditional network service management system development accomplish hardware management, performance management, desktop management, and other various management functions upper management software system through agents or direct calls to the underlying service management interface. In this development the way, this coupling of network service management system and network equipment management system is focused on low flexibility and poor, it is difficult to meet the diverse management needs of service. In order to ensure that the network has a good performance and reliability, to provide users with high-quality service, we must change the existing network management system development way.Therefore, the development of a tiered network service management system is a neccessary. A virtualization model of network services management is proposed in this paper, which supports development of network services management system. This model uses a virtual management thinking and modeling techniques, mainly includes two parts:the establishment of the relational model of network services and network service index model. Network service relationship model describes the hierarchical relationship between the network services, network service index model analyzes management indicators which are including the static index and the dynamic index such as service availability, performance, utilization and throughput metrics. In this article using object database MongoDB storage virtualization model. The Vaadin visualization techniques achieve the visualization of the model. By virtualization show, you can locate the position of the service, clear and accurate understand of the operational status of various network services, network services fault detection and location in order to achieve the visual management of network services.
