【摘要】：數(shù)據(jù)中心已經(jīng)成為承載大規(guī)模數(shù)據(jù)計(jì)算和存儲(chǔ)的重要基礎(chǔ)設(shè)施，而快速、高效的數(shù)據(jù)中心網(wǎng)拓?fù)浒l(fā)現(xiàn)對(duì)于數(shù)據(jù)中心的正常管理和運(yùn)行有著至關(guān)重要的意義。當(dāng)前數(shù)據(jù)中心網(wǎng)絡(luò)主要由大量二層交換機(jī)和三層交換機(jī)組成，而由于二層交換機(jī)的透明性，一般的網(wǎng)絡(luò)拓?fù)浒l(fā)現(xiàn)算法難以發(fā)現(xiàn)。論文結(jié)合數(shù)據(jù)中心網(wǎng)絡(luò)不同層次交換機(jī)并存的特點(diǎn)，從網(wǎng)絡(luò)層和數(shù)據(jù)鏈路層兩個(gè)層次對(duì)網(wǎng)絡(luò)拓?fù)浒l(fā)現(xiàn)技術(shù)進(jìn)行了研究，論文的主要工作和創(chuàng)新點(diǎn)如下： （1）論文介紹了數(shù)據(jù)中心網(wǎng)絡(luò)結(jié)構(gòu)，闡述了網(wǎng)絡(luò)管理與拓?fù)浒l(fā)現(xiàn)的意義，對(duì)拓?fù)浒l(fā)現(xiàn)需要用到的SNMP協(xié)議，生成樹協(xié)議進(jìn)行了研究，分析了交換機(jī)的工作有原理。 （2）設(shè)計(jì)了網(wǎng)絡(luò)層拓?fù)浒l(fā)現(xiàn)算法。針對(duì)網(wǎng)絡(luò)層拓?fù)浒l(fā)現(xiàn)設(shè)計(jì)了一種基于SNMP協(xié)議的拓?fù)浒l(fā)現(xiàn)算法，主要是基于SNMP協(xié)議獲得MIB庫(kù)中的拓?fù)湫畔�，再通過(guò)對(duì)獲取信息的分析處理，知道整個(gè)網(wǎng)絡(luò)的拓?fù)浣Y(jié)構(gòu)。 （3）設(shè)計(jì)了一種基于生成樹協(xié)議的鏈路層拓?fù)浒l(fā)現(xiàn)算法。由于交換機(jī)硬件內(nèi)在的透明性，交換設(shè)備只會(huì)在執(zhí)行STP協(xié)議時(shí)與其相鄰的設(shè)備進(jìn)行信息交換，普通用戶在使用網(wǎng)絡(luò)的過(guò)程中一般察覺(jué)不到交換機(jī)的存在。論文通過(guò)獲取生成樹協(xié)議的相關(guān)信息并結(jié)合Bridge MIB變量來(lái)判斷交換機(jī)的連接關(guān)系，，進(jìn)而得到鏈路層的拓?fù)浣Y(jié)構(gòu)。 （4）通過(guò)對(duì)Shortest Path Bridging（SPB）技術(shù)進(jìn)行的分析和研究，論證了SPB技術(shù)在數(shù)據(jù)中心網(wǎng)絡(luò)中應(yīng)用的可行性。 （5）基于上面的兩種算法設(shè)計(jì)了一個(gè)原型系統(tǒng)，對(duì)原型系統(tǒng)結(jié)構(gòu)進(jìn)行了說(shuō)明，對(duì)如何實(shí)現(xiàn)模塊功能進(jìn)行了詳細(xì)分析，并構(gòu)建網(wǎng)絡(luò)環(huán)境對(duì)原型系統(tǒng)進(jìn)行了驗(yàn)證，對(duì)測(cè)試結(jié)果進(jìn)行了分析，驗(yàn)證了算法的可行性。 綜上所述，本文基于SNMP協(xié)議和生成樹協(xié)議設(shè)計(jì)了數(shù)據(jù)中心網(wǎng)絡(luò)網(wǎng)絡(luò)層和鏈路層的拓?fù)浒l(fā)現(xiàn)算法，并在算法基礎(chǔ)上設(shè)計(jì)實(shí)現(xiàn)了一個(gè)原型系統(tǒng)，經(jīng)過(guò)實(shí)驗(yàn)測(cè)試驗(yàn)證了算法的正確性。
[Abstract]:Data center has become an important infrastructure for carrying large data computing and storage, and rapid and efficient data center network topology discovery is of vital importance to the normal management and operation of data centers. The current data center network is composed mainly of a large number of two layer switching machines and three layer switches, and because of the two layer switching. The general network topology discovery algorithm is difficult to find. This paper studies the network topology discovery technology from two levels of network layer and data link layer. The main work and innovation of this paper are as follows:
(1) the paper introduces the network structure of data center, expounds the significance of network management and topology discovery, studies the SNMP protocol which needs to be used in the topology discovery, and studies the spanning tree protocol, and analyzes the principle of the work of the switch.
(2) the network layer topology discovery algorithm is designed. A topology discovery algorithm based on SNMP protocol is designed for the network layer topology discovery, which is mainly based on the SNMP protocol to obtain the topology information in the MIB library, and then through the analysis and processing of the acquired information, the topology of the whole network is known.
(3) a link layer topology discovery algorithm based on the spanning tree protocol is designed. Because of the internal transparency of the switch hardware, the exchange device will only exchange information with its adjacent equipment when the STP protocol is executed. The common user can not detect the existence of the switch in the process of using the network. The Bridge MIB variable is used to judge the connection relationship of the switch and get the topology of the link layer.
(4) through the analysis and research of Shortest Path Bridging (SPB) technology, the feasibility of SPB technology in data center network is demonstrated.
(5) a prototype system is designed based on the above two algorithms, the structure of the prototype system is explained, the function of how to realize the module is analyzed in detail, and the network environment is constructed to verify the prototype system, and the test results are analyzed, and the feasibility of the calculation method is verified.
To sum up, based on the SNMP protocol and the spanning tree protocol, the topology discovery algorithm of the network layer and link layer of the data center is designed, and a prototype system is designed and implemented on the basis of the algorithm, and the correctness of the algorithm is verified by the experimental test.
