【摘要】 随着网络规模的日益复杂,出现了大型复杂网络的概念,大型复杂网络具有被管对象极其复杂且种类繁多,业务多样化,对安全性和私密性要求较高等特点,这将导致直接使用传统的网络管理模型会出现管理力度不够,效率低下,甚至系统失效、网络崩溃等问题。为了弥补传统网络管理的缺点与不足,提高网络管理的性能,大型复杂网络的网络管理的研究被提上日程。更多还原

【Abstract】 With the development of the scale of network, current network management model cannot manage the network efficiently now. To complement the weaknesses, the complex network management is being put on the research agenda. The occurrence of XML technology brings a new chance for the development of network management, and has been a new tendency for the development of network management. Using XML in network management presents many advantages: (1) The XML Schema defines the structure of management information in a flexible manner. (2) Widely deployed protocols such as HTTP reliably transfer management data. (3) Using DOM APIs can easily access and manipulate management data from applications. In a word, XML technology can make up the limitation of traditional network management protocol. Policy based networking has emerged as a popular approach to automating network management, Policy-based network management is an intelligent network management. It can make the works of network manager more and more convenient. It divide manage behavior into two parts: contol and execute. Policies are high-level rules and procedures that abstract and simplify the management of complex network devices and technologies, they can be seen as plans of an organization to achieve its objectives. A policy is a specification of a objective to be achieved or a set of actions to be performed in the future. In this model, The network management is independent of the core stations, the management informantion is independent between every region and the network flow will reduce. It can make the network management more and more flexible, effective and reliable. According to the advantages of the XML and policy technology, we give an network management for complex networks based on XML and policy, analyze the structure and the components of this model, and finally, an prototype that designed and implemented on above methods and technologies, named XPBNM, is introduced. XPBNM can completely perform fault management, browsering of management information base, configration management and so on, and in the management system, management information is described with XML format.更多还原
