【摘要】：隨著計算機技術(shù)的迅猛發(fā)展，網(wǎng)絡(luò)需求不斷增大，數(shù)據(jù)中心作為數(shù)據(jù)管理的集中地和一切IT服務(wù)的基礎(chǔ)，其網(wǎng)絡(luò)性能直接關(guān)系到整個網(wǎng)絡(luò)服務(wù)功能能否實現(xiàn)及實現(xiàn)的質(zhì)量。對數(shù)據(jù)中心環(huán)境下的網(wǎng)絡(luò)進行適時和準確地性能測量，是實施有效的維護和管理、優(yōu)化調(diào)整流量策略、提升數(shù)據(jù)中心運行質(zhì)量的前提。 當前有些數(shù)據(jù)中心網(wǎng)絡(luò)環(huán)境相對復(fù)雜，主要體現(xiàn)在內(nèi)部網(wǎng)絡(luò)的多種異構(gòu)網(wǎng)絡(luò)融合部署。本文設(shè)計實現(xiàn)的系統(tǒng)運行環(huán)境是數(shù)據(jù)中心內(nèi)網(wǎng)(融合了IB網(wǎng)和以太網(wǎng))與互聯(lián)網(wǎng)互連的網(wǎng)絡(luò)結(jié)構(gòu)。相對于單一網(wǎng)絡(luò)結(jié)構(gòu)而言，這種網(wǎng)絡(luò)測量系統(tǒng)既要實現(xiàn)對數(shù)據(jù)中心內(nèi)網(wǎng)中的各個子網(wǎng)進行性能測量，又要實現(xiàn)數(shù)據(jù)中心內(nèi)部網(wǎng)絡(luò)與互聯(lián)網(wǎng)中任一節(jié)點之間的性能測量，增加了測量的困難。 論文的主要研究了以下內(nèi)容：一是分析了數(shù)據(jù)中心網(wǎng)絡(luò)性能測量的研究背景和意義；二是介紹了網(wǎng)絡(luò)性能測量相關(guān)技術(shù)，包括測量參數(shù)、測量方式、相關(guān)算法、測量工具等。重點分析了數(shù)據(jù)中心環(huán)境下同時實現(xiàn)對數(shù)據(jù)中心內(nèi)部網(wǎng)絡(luò)與互聯(lián)網(wǎng)中任一節(jié)點之間，以及數(shù)據(jù)中心內(nèi)部網(wǎng)絡(luò)的本網(wǎng)節(jié)點之間分別進行測量的難點，歸納了數(shù)據(jù)中心網(wǎng)絡(luò)性能測量的實施步驟；三是針對數(shù)據(jù)中心環(huán)境下實現(xiàn)內(nèi)部服務(wù)器與互聯(lián)網(wǎng)中任一節(jié)點之間進行性能測量過程中無法取得節(jié)點協(xié)作的實際，，以Pathneck源程序為基礎(chǔ)，改進并設(shè)計了一種采用自適應(yīng)方法測量互聯(lián)網(wǎng)性能的工具Pathteck，在盡量減小對網(wǎng)絡(luò)負載影響的前提下提高了測量精度；四是分析了數(shù)據(jù)中心內(nèi)部網(wǎng)絡(luò)中的IB網(wǎng)和以太網(wǎng)結(jié)構(gòu)及網(wǎng)絡(luò)性能特點，介紹了測量IB網(wǎng)的工具Qperf；設(shè)計了分布式的、支持圖形化界面的性能測量工具Tperf，實驗證明其測量效果；五是在綜合了對互聯(lián)網(wǎng)、IB網(wǎng)和以太網(wǎng)絡(luò)性能測量的分析研究和測量工具改進、選擇的基礎(chǔ)上，設(shè)計實現(xiàn)了一套數(shù)據(jù)中心環(huán)境下的網(wǎng)絡(luò)性能測量系統(tǒng)，系統(tǒng)采用集中管理的辦法和Client/Server分離的結(jié)構(gòu)方式，實現(xiàn)了數(shù)據(jù)中心環(huán)境對數(shù)據(jù)中心內(nèi)部服務(wù)器與互聯(lián)網(wǎng)中任一節(jié)點、數(shù)據(jù)中心內(nèi)網(wǎng)中的以太網(wǎng)和IB網(wǎng)絡(luò)進行性能測量的功能，通過實驗證明運行效果較好。
[Abstract]:With the rapid development of computer technology, the demand of network is increasing. Data center is the centralized place of data management and the basis of all IT services. Its network performance is directly related to whether or not the whole network service function can be realized and the quality of realization. It is an effective maintenance and management to measure the network performance in a timely and accurate manner under the data center environment. Optimize and adjust the flow strategy and improve the operation quality of the data center. At present, some data center network environments are relatively complex. The system running environment designed and implemented in this paper is the data center intranet (integrating IB network and Ethernet). Network structure for interconnection with the Internet. Compared to a single network structure. This network measurement system not only realizes the performance measurement of each subnet in the data center inner network, but also realizes the performance measurement between the data center internal network and any node in the Internet. It increases the difficulty of measurement. The main contents of this paper are as follows: firstly, the research background and significance of data center network performance measurement are analyzed; The second is to introduce the network performance measurement technology, including measurement parameters, measurement methods, correlation algorithm. Measurement tools and so on. Emphasis is placed on the difficulties of simultaneous measurement between the data center internal network and any node in the Internet, and between the data center internal network and the local network nodes in the data center environment. The implementation steps of data center network performance measurement are summarized. The third is to realize the performance measurement between the internal server and any node in the Internet under the data center environment, which can not achieve node cooperation, based on the Pathneck source program. This paper improves and designs a tool named Pathteck, which uses adaptive method to measure Internet performance, and improves the accuracy of measurement under the premise of minimizing the influence on network load. Fourthly, the structure and performance of IB network and Ethernet in data center are analyzed, and the tool of measuring IB network is introduced. A distributed performance measurement tool, Tperfwhich supports graphical interface, is designed, and its measurement effect is proved by experiments. Fifthly, a network performance measurement system under the data center environment is designed and implemented on the basis of synthesizing the analysis, research and improvement of the performance measurement tools of the Internet and Ethernet network, and on the basis of the selection of the measurement tools, a set of network performance measurement system under the data center environment is designed and implemented. The system adopts the method of centralized management and the structure of Client/Server separation to realize the data center environment to any node in the data center internal server and Internet. The performance of Ethernet and IB network in data center is measured.
