【摘要】：現(xiàn)有的網(wǎng)絡(luò)管理軟件需要真實(shí)的網(wǎng)絡(luò)環(huán)境作為支撐,實(shí)現(xiàn)網(wǎng)絡(luò)監(jiān)視和管理的功能。如果在真實(shí)的網(wǎng)絡(luò)環(huán)境中進(jìn)行網(wǎng)絡(luò)管理軟件的開(kāi)發(fā)和測(cè)試,不僅需要耗費(fèi)大量人力物力進(jìn)行網(wǎng)絡(luò)環(huán)境的搭建,而且網(wǎng)絡(luò)數(shù)據(jù)的采集及分析也存在一定困難。網(wǎng)絡(luò)模擬軟件的出現(xiàn),使網(wǎng)絡(luò)管理軟件的設(shè)計(jì)和開(kāi)發(fā)的工作變得高效,同時(shí)也省去了測(cè)試網(wǎng)絡(luò)環(huán)境的搭建費(fèi)用。 本文描述的網(wǎng)絡(luò)狀態(tài)模擬軟件,是在原有SNMP數(shù)據(jù)錄制回放軟件的基礎(chǔ)上,著重研究各類網(wǎng)絡(luò)環(huán)境,使各類網(wǎng)絡(luò)事件通過(guò)交換機(jī)的SNMP數(shù)據(jù)的方式進(jìn)行重現(xiàn),從而模擬各類交換機(jī)事件,重現(xiàn)相應(yīng)的網(wǎng)絡(luò)狀態(tài)。本軟件可以在服務(wù)器上搭建一個(gè)仿真網(wǎng)絡(luò)環(huán)境,研究人員利用這個(gè)虛擬網(wǎng)絡(luò),在前期對(duì)現(xiàn)有網(wǎng)絡(luò)管理軟件進(jìn)行設(shè)計(jì)研究,中期對(duì)網(wǎng)絡(luò)環(huán)境進(jìn)行針對(duì)性的開(kāi)發(fā)工作,后期對(duì)其功能、性能等方面進(jìn)行測(cè)試和評(píng)價(jià)。另外,軟件模擬的網(wǎng)絡(luò)狀態(tài)也給開(kāi)發(fā)人員提供了更快速、直觀的參照,為網(wǎng)絡(luò)管理軟件的優(yōu)化設(shè)計(jì)提供更便捷、有效的手段。 本文描述了一種面向各類網(wǎng)絡(luò)狀態(tài)模擬的軟件的設(shè)計(jì)與實(shí)現(xiàn)。首先介紹了基于SNMP仿真代理的研究現(xiàn)狀,重點(diǎn)描述了現(xiàn)有方案在網(wǎng)絡(luò)狀態(tài)模擬方面的不足,接下來(lái)針對(duì)這方面的不足,結(jié)合項(xiàng)目組現(xiàn)有網(wǎng)絡(luò)管理軟件的具體情況,提出了本網(wǎng)絡(luò)狀態(tài)模擬軟件的總體需求。之后針對(duì)總體需求,設(shè)計(jì)相應(yīng)的解決方案和軟件架構(gòu),包括背景數(shù)據(jù)流生成、交換機(jī)事件模擬、Agent數(shù)據(jù)回放和腳本自動(dòng)控制四個(gè)方面,并詳細(xì)描述了各個(gè)功能的設(shè)計(jì)與實(shí)現(xiàn)。接下來(lái),對(duì)各項(xiàng)功能進(jìn)行全面的功能和性能測(cè)試,充分驗(yàn)證了本軟件在網(wǎng)絡(luò)狀態(tài)模擬方面的測(cè)試用例全面、測(cè)試數(shù)據(jù)具有針對(duì)性、測(cè)試過(guò)程自動(dòng)化等優(yōu)勢(shì)。最后對(duì)本文設(shè)計(jì)實(shí)現(xiàn)的網(wǎng)絡(luò)狀態(tài)模擬方法提出待改進(jìn)的方面和下一步研究方向。
[Abstract]:The existing network management software needs the real network environment as the support, realizes the network monitoring and the management function. If the network management software is developed and tested in the real network environment, it not only needs a lot of manpower and material resources to build the network environment, but also has some difficulties in the collection and analysis of network data. The appearance of network simulation software makes the design and development of network management software more efficient and saves the cost of testing network environment. The network state simulation software described in this paper is based on the original SNMP data recording and playback software, focusing on the study of various network environments, so that all kinds of network events can be reproduced through the SNMP data of the switch. Thus all kinds of switch events are simulated and the corresponding network states are reproduced. This software can set up a simulation network environment on the server. Researchers can use the virtual network to design and study the existing network management software in the early stage, and develop the network environment in the middle period. The function, performance and other aspects of the test and evaluation. In addition, the network state of software simulation also provides developers with a faster and more intuitive reference, and provides a more convenient and effective means for the optimization design of network management software. This paper describes the design and implementation of a software for network state simulation. Firstly, this paper introduces the research status of simulation agent based on SNMP, and describes the shortcomings of the existing scheme in network state simulation. Then, according to the shortcomings of this aspect, combined with the specific situation of the project team's existing network management software, The overall requirement of network state simulation software is presented. Then, according to the overall requirements, the corresponding solution and software architecture are designed, including background data stream generation, switch event simulation agent data playback and script automatic control. The design and implementation of each function are described in detail. Then, the comprehensive functional and performance tests are carried out, which fully verify the advantages of the software in network state simulation, such as comprehensive test cases, targeted test data, automation of test process, and so on. Finally, the network state simulation method designed and implemented in this paper is proposed for improvement and the next research direction.
