基于拓扑发现技术的资源管理系统的设计与实现
摘要
随着大规模网络的激增,网络的复杂性和异构性的特点日益突出,加强电信网络资源管理成为当前各级电信企业迫切需要解决的重要任务。然而,传统电信网络资源管理大部分只停留在静态管理的状态,无法实现资源信息的实时性更新,保证资源数据的准确性和一致性。如何快速准确的实现网络资源搜索和定位,实时更新资源信息,捕捉网络中资源的变化,是当前资源管理系统研究的重点。
本课题针对资源管理系统建设的要求,应用拓扑自动发现技,利用SNMP以及生成树协议等原理,通过对“环境及动力设备监控系统”中的网络资源的深入研究,结合网络中各种资源的特点和逻辑关系,设计和开发了基于拓扑发现技术的资源管理系统。通过这套系统的设计和开发,对资源管理的理论和拓扑自动发现技术有了深入的掌握和思考。
论文首先研究和阐述了网络资源管理的理论和拓扑发现技术。接下来通过分析“环境及动力设备监控系统”的网络资源特点,设计了一套资源管理方案。依据以上设计的资源管理方案,实现了拓扑发现模块和资源管理模块两个核心模块,从而实现了具有实时网络拓扑发现功能的资源管理系统。通过测试表明,这套资源管理系统能够准确跟踪网络中资源的变化,提高了网络管理人员对网络资源的掌握准确性和实时性。
With the proliferation of large-scale network, the complexity and structure difference are more outstanding, the enhancement of telecom network resource management has been an urgent task to be resolved. But most of traditional telecom network resource management is still static management state, the resource information can't be updated on time, and the veracity and the coherence can't be guaranteed. How to search and locate the network resource fast and exactly, catch the change of resource on time are the research emphases of resource management system.
The task aims to meet the requirement of resource management system, topology discovery technology, SNMP and STP are applied. I researched deeply into the network resource of "Environment and Power Devices Monitor System", combined the characteristic and logic relationship of resources in the network, designed and developed the Resource Management System based on Topology Discovery. Through the system, I got a deep mastery and thinking for the theory of resource management and the technology of topology discovery.
The article firstly gives the knowledge of network resource management and topology discovery. Then by analyzing the network resource characteristics of "Environment and Power Devices Monitor System", I designed the project of resource management. According to the solution, I implemented the topology discovery module and resource management module, which are core modules of the system, so the Real-Time Network Topology Discovery Resource Management System is implemented. The test of the system indicated that this resource management system can track the resource change of the network. The veracity and real time level of network resource control for network administrators are improved.
