【摘要】：數(shù)據(jù)中心已經(jīng)成為承載大規(guī)模數(shù)據(jù)計算和存儲的重要基礎設施，而快速、高效的數(shù)據(jù)中心網(wǎng)拓撲發(fā)現(xiàn)對于數(shù)據(jù)中心的正常管理和運行有著至關重要的意義。當前數(shù)據(jù)中心網(wǎng)絡主要由大量二層交換機和三層交換機組成，而由于二層交換機的透明性，一般的網(wǎng)絡拓撲發(fā)現(xiàn)算法難以發(fā)現(xiàn)。論文結合數(shù)據(jù)中心網(wǎng)絡不同層次交換機并存的特點，從網(wǎng)絡層和數(shù)據(jù)鏈路層兩個層次對網(wǎng)絡拓撲發(fā)現(xiàn)技術進行了研究，論文的主要工作和創(chuàng)新點如下： （1）論文介紹了數(shù)據(jù)中心網(wǎng)絡結構，闡述了網(wǎng)絡管理與拓撲發(fā)現(xiàn)的意義，對拓撲發(fā)現(xiàn)需要用到的SNMP協(xié)議，生成樹協(xié)議進行了研究，分析了交換機的工作有原理。 （2）設計了網(wǎng)絡層拓撲發(fā)現(xiàn)算法。針對網(wǎng)絡層拓撲發(fā)現(xiàn)設計了一種基于SNMP協(xié)議的拓撲發(fā)現(xiàn)算法，主要是基于SNMP協(xié)議獲得MIB庫中的拓撲信息，再通過對獲取信息的分析處理，知道整個網(wǎng)絡的拓撲結構。 （3）設計了一種基于生成樹協(xié)議的鏈路層拓撲發(fā)現(xiàn)算法。由于交換機硬件內在的透明性，交換設備只會在執(zhí)行STP協(xié)議時與其相鄰的設備進行信息交換，普通用戶在使用網(wǎng)絡的過程中一般察覺不到交換機的存在。論文通過獲取生成樹協(xié)議的相關信息并結合Bridge MIB變量來判斷交換機的連接關系，，進而得到鏈路層的拓撲結構。 （4）通過對Shortest Path Bridging（SPB）技術進行的分析和研究，論證了SPB技術在數(shù)據(jù)中心網(wǎng)絡中應用的可行性。 （5）基于上面的兩種算法設計了一個原型系統(tǒng)，對原型系統(tǒng)結構進行了說明，對如何實現(xiàn)模塊功能進行了詳細分析，并構建網(wǎng)絡環(huán)境對原型系統(tǒng)進行了驗證，對測試結果進行了分析，驗證了算法的可行性。 綜上所述，本文基于SNMP協(xié)議和生成樹協(xié)議設計了數(shù)據(jù)中心網(wǎng)絡網(wǎng)絡層和鏈路層的拓撲發(fā)現(xiàn)算法，并在算法基礎上設計實現(xiàn)了一個原型系統(tǒng)，經(jīng)過實驗測試驗證了算法的正確性。
[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.
