【摘要】：随着计算机技术和网络技术的发展,企业的信息化程度越来越高,企业园区中的网络资源也越来越多,网络设备被广泛的应用在企业的生产、业务、办公和管理中,发挥了重要的作用。因此,高效的监控和管理企业园区内的网络资源,保证企业网络有效运行,是维持企业正常运转的重要基础。本文为此基于SNMP协议(Simple Net Management Protocol,简单网络管理协议)设计和实现了一套企业园区网资源监控系统,实现了对园区网络资源的有效监控和管理,提高了企业网络资源的利用效率,加强了对网络设备的管理和维护,规范了用户在园区网中的活动,增强了园区网络的稳定性与可靠性。同时,该系统增加了物联网模块,能大幅提升企业的信息化程度,有助于企业借助物联网实施"智慧园区"和"智慧企业"。[1]本文首先简要的分析了企业园区网络资源监控和管理系统的研发背景,总结了该系统目前的国内外发展现状,并在此基础上分析了系统的需求,归纳出MIB查询、SNMP设置、设备异常告警和物联网管理四个业务性功能模块以及权限管理、系统设置和日志管理等支持性功能模块。其次,本文简述了系统的设计原则和目标,针对系统的总体需求,基于SNMP协议设计了系统的技术架构,包括系统的逻辑架构和物理结构,根据用户、SNMP管理器、SNMP代理和网络设备四个层次,设计了系统的功能结构,描述了系统的总体实现方案,并分析了系统的安全性设计。第三,本文对系统进行了详细设计,描述了系统的建模工作,根据系统需求分析中的功能用例,将系统整体分解为多个业务模块,设计了系统的业务模型以及动态架构和静态架构,介绍了系统各个模块的工作方式和模块之间的通信机制,并详细介绍了系统中主要功能模块的设计方案,以及系统的数据库设计,描述了主要的数据库表。第四,本文对系统的实现工作进行了详细的介绍,描述了系统的总体实现方案、工具及环境,根据系统的功能模块设计,分别介绍了系统中各个功能模块及数据库、界面和输入输出等支持模块的具体实现方法,展示了系统的部分界面效果,并通过白盒测试、黑盒测试(功能测试)和性能测试三种测试方法分别对系统的程序和逻辑、功能和性能进行了测试,介绍了测试过程和结果。最后,本文总结了在需求分析、设计、实现和测试过程中的经验,归纳了系统开发的结论,分析了系统在实际应用中的不足之处,并基于物联网和"智慧园区"对系统的未来进行了展望。综上所述,本文在企业园区网络资源监控工作的需求分析基础上,设计和实现了基于SNMP协议的企业园区网资源监控系统,并进行了测试和运行。
[Abstract]:With the development of computer technology and network technology, the degree of enterprise informatization is becoming higher and higher, and the network resources in the enterprise park are more and more. The network equipment is widely used in the production, business, office and management of the enterprise. Played an important role. Therefore, the efficient monitoring and management of the network resources in the enterprise park to ensure the effective operation of the enterprise network is an important foundation to maintain the normal operation of the enterprise. This paper designs and implements a set of enterprise park network resource monitoring system based on SNMP protocol (Simple Net Management Protocol,), realizes the effective monitoring and management of the park network resource, and improves the efficiency of enterprise network resource utilization. The management and maintenance of network equipment are strengthened, the activities of users in campus network are standardized, and the stability and reliability of campus network are enhanced. At the same time, the system has added the Internet of things module, which can greatly improve the level of enterprise information. It is helpful for enterprises to implement "wisdom park" and "intelligent enterprise" with the help of the Internet of things. [1] this paper first briefly analyzes the research and development background of the enterprise park network resource monitoring and management system, and summarizes the current development situation of the system at home and abroad. On this basis, the requirements of the system are analyzed, and four business function modules, such as MIB query setting, device abnormal alarm and Internet of things management, as well as the supporting function modules such as privilege management, system setup and log management, are summed up. Secondly, this paper briefly describes the design principles and objectives of the system. According to the overall requirements of the system, this paper designs the technical framework of the system based on SNMP protocol, including the logical structure and physical structure of the system. According to the four layers of SNMP agent and network equipment, the function structure of the system is designed, the overall implementation scheme of the system is described, and the security design of the system is analyzed. Thirdly, this paper designs the system in detail, describes the modeling work of the system, decomposes the whole system into several business modules according to the function cases in the system requirement analysis. The business model, dynamic architecture and static structure of the system are designed. The working mode of each module and the communication mechanism between the modules are introduced, and the design scheme of the main functional modules in the system is introduced in detail. And the database design of the system, described the main database tables. Fourth, this paper introduces the implementation of the system in detail, describes the overall implementation of the system, tools and environment, according to the system functional module design, respectively, introduced the system each functional module and database. The specific implementation methods of interface and input / output modules are presented, and some of the interface effects of the system are shown. The program and logic of the system are tested by three test methods: White box test, black box test (function test) and performance test, respectively. The function and performance are tested, and the test process and results are introduced. Finally, this paper summarizes the experience in the process of requirement analysis, design, implementation and testing, summarizes the conclusions of system development, and analyzes the shortcomings of the system in practical application. The future of the system is prospected based on the Internet of things and Intelligence Park. To sum up, based on the requirement analysis of enterprise park network resource monitoring, this paper designs and implements the enterprise park network resource monitoring system based on SNMP protocol, and carries on the test and the operation.
