【摘要】：隨著云計算等網(wǎng)絡應用的快速發(fā)展,現(xiàn)有網(wǎng)絡性能是否足以承載上層應用變得越來越難以預見。準確、高效的網(wǎng)絡測量工具所獲得的數(shù)據(jù)可以被用來更合理地進行網(wǎng)絡規(guī)劃或準確地定位關鍵網(wǎng)絡設備與節(jié)點,降低網(wǎng)絡建設與維護成本。華為南京分公司希望能夠通過網(wǎng)絡測量等手段發(fā)現(xiàn)洲際互聯(lián)網(wǎng)通信網(wǎng)絡中的一些關鍵網(wǎng)絡設備(如對網(wǎng)絡傳輸能力產生瓶頸制約作用的路由、線路等),但常見的的網(wǎng)絡測量工具都不能很好地滿足目前的需求,尤其在網(wǎng)絡拓撲信息的測量上。為此開發(fā)多協(xié)議網(wǎng)絡測量系統(tǒng)設計用于互聯(lián)網(wǎng)流量相關性能指標以及網(wǎng)絡拓撲相關信息的測量,旨在通過對獲取到的網(wǎng)絡性能測量數(shù)據(jù)與網(wǎng)絡拓撲測量數(shù)據(jù)的交叉對比來深入分析網(wǎng)絡通信狀況。作者項目期間對目前主流的網(wǎng)絡測量工具進行了調研,對比了不同工具的優(yōu)勢及適用場景,并參與討論項目需求,在Mentor指導下承擔了整個網(wǎng)絡測量系統(tǒng)的軟件開發(fā)工作。本多協(xié)議網(wǎng)絡測量系統(tǒng)采用主動測量工作方式,架構為混合式P2P結構,工作時通過索引服務器對參與測量的終端服務器進行任務配置和管理。在設計上采用多種測量協(xié)議,在網(wǎng)絡防火墻對某些協(xié)議進行限制時提供更多的選擇；在實現(xiàn)網(wǎng)絡拓撲測量功能時融入了Paris-traceroute技術,排除了假鏈路對測量結果的干擾。目前多協(xié)議網(wǎng)絡測量系統(tǒng)已完成項目一期要求的十次測量任務,測量數(shù)據(jù)已經(jīng)用于對網(wǎng)絡傳輸性能參數(shù)以及傳輸路徑信息的分析與發(fā)掘。
[Abstract]:With the rapid development of cloud computing and other network applications, it is more and more difficult to predict whether the existing network performance can support the upper applications. The data obtained by the accurate and efficient network measurement tools can be used to plan the network more reasonably or locate the key network devices and nodes accurately and reduce the cost of network construction and maintenance. Huawei's Nanjing branch hopes to be able to discover some of the key network devices in the intercontinental Internet communication network, such as routing, which has a bottleneck effect on network transmission capacity, through network measurements and other means. Lines and so on, but common network measurement tools can not meet the current needs, especially in the measurement of network topology information. For this purpose, a multi-protocol network measurement system is designed for the measurement of Internet traffic related performance indicators and network topology related information. The purpose of this paper is to analyze the network communication by comparing the obtained network performance measurement data with the network topology measurement data. During the project, the author investigated the current mainstream network measurement tools, compared the advantages and applicable scenarios of different tools, and participated in the discussion of project requirements. Under the guidance of Mentor, the author undertook the software development work of the whole network measurement system. The multi-protocol network measurement system adopts the active measurement mode and the architecture is a hybrid P2P structure. The task configuration and management of the terminal server involved in the measurement are carried out through the index server. A variety of measurement protocols are used in the design to provide more choices when some protocols are restricted by the network firewall, and the Paris-traceroute technology is incorporated into the network topology measurement function to eliminate the interference of the false link to the measurement results. At present, the multi-protocol network measurement system has completed ten measurement tasks required in the first phase of the project. The measured data have been used to analyze and excavate the network transmission performance parameters and transmission path information.
