【摘要】 自从八十年代末期SNMP(Simple Network Management Protocol)简单网络管理协议面世以来,网络管理技术在短短的十几年里得到了突飞猛进的发展,随着管理功能的增强和管理对象的扩大,网络管理技术正逐步成为网络构建和维护中必不可少的重要因素。 由于网络技术的发展,网络的规模和复杂度越来越大,传统的网络管理协议已经越来越不能满足网络管理的要求。当前Web技术的成熟和XML的蓬勃发展给网络管理注入了新的活力,也给网络管理技术和模式带来了一次革命。因此,把XML技术和Web技术应用于网络管理之中,是网络管理技术的一种有潜力的解决方案。 本文分析了网络管理的协议、功能以及它基本的理论和管理模型,尤其分析了被广泛支持的网络管理模型和协议——SNMP协议,比较了常见的网络管理体系结构及其适用的场合,并在基于Web的网络管理的基础上,结合XML技术,提出了一种具体的方案模型——基于Web和XML的网络管理。 本文所采用的方案扩展了基于Web的网络管理的概念模型,采用绑定于HTFP协议的SOAP协议进行传输,定义了在网络管理协议中常用的一些系统操作,并考虑到与现存的网络管理协议兼容的问题,引入了一个XML/SNMP的网关,能够实现XML与SNMP协议之间在处理操作、消息和协议等三个层面进行相互转换,同时给出了一种实现SNMP协议的具体解决方案。 本课题采用了目前解决异构平台、异构和远程网络不具有统一规则和互操作性的多种技术,尤其是XML技术、Web技术和SOAP技术,它们对今后建立大型网络环境下的综合网管系统具有一定的启示作用。更多还原

【Abstract】 Network management technology has being developing rapidly since SNMP (Simple Network Management Protocol) was published at the end of 1980s.It becomes an essential element in constructing and maintaining networks along with the enhancement of management functions and expanding of managed objects.With the rapid development of the network technology, the scale and complexity of networks has increased greatly. Under this background, the traditional management protocols can not meet the requirement of network management. The maturity of Web technology and the flourishing development of XML have brought a new revolution to network management technology and mode. It seems that, XML-based and Web-based technologies have been emerging as a promising approach to network management.This paper first analyzes the protocols and functions of network management, along with its basic theory and models. The widely supported SNMP is especially discussed. Then common network management architectures are compared from several aspects, including their suitable applications. A concrete solution—network management based on both Web and XML is finally brought forward on the foundation of web-based network management, combining with XML-related technologies.The proposed approach in this paper is the extension of the network management conceptual model based on Web. The Simple Object Access Protocol (SOAP) is chosen to bind over HTTP for transporting. The system operations, which are used most frequently in network management protocols, are also defined. In order to deal with the problems of compatibility with legacy system supporting the SNMP, an XML/SNMP gateway is then introduced .The gateway achieves the goal of interaction translation between XML and SNMP at three levels—the process level, the message level and the protocol level. A possible scenario to implement the SNMP is presented.Utilizing several new techniques, which are currently used to solve the problems existing in the heterogeneous system platforms for the purpose of interoperability, especially XML-based technologies, Web-based technologies and SOAP, the result of this study provides theoretical and practical supports for synthetical network management system under large-scale network environment.更多还原
