【摘要】：流量工程,也可稱為業(yè)務(wù)量規(guī)劃,是網(wǎng)絡(luò)運營商對網(wǎng)絡(luò)資源的分配和優(yōu)化利用的問題,一般包括網(wǎng)絡(luò)規(guī)劃,流量測量和分析,網(wǎng)絡(luò)控制和優(yōu)化。網(wǎng)絡(luò)流量工程解決的主要問題是從資源和流量兩個角度實現(xiàn)網(wǎng)絡(luò)整體性能的優(yōu)化。從資源的角度,主要目標是有效管理網(wǎng)絡(luò)資源,合理分配網(wǎng)絡(luò)負載和利用網(wǎng)絡(luò)資源。從流量的角度,分析解決的問題包括：減少延時,降低丟包概率,提高網(wǎng)絡(luò)吞吐量。流量工程最重要的思想就是通過各種技術(shù)實現(xiàn)全網(wǎng)流量的優(yōu)化配置,提升網(wǎng)絡(luò)的服務(wù)質(zhì)量。 因此,本文在依照SDN/OF的思想和所提供條件的基礎(chǔ)上,利用復(fù)雜網(wǎng)絡(luò)相關(guān)的技術(shù),通過實現(xiàn)一個流量分析系統(tǒng)以解決流量分析中的相關(guān)問題。其中包括：讀取數(shù)據(jù),建立模型,分析網(wǎng)絡(luò)中的特征指標,實現(xiàn)典型的流量分析算法,.提供豐富的數(shù)據(jù)和結(jié)果的可視化功能等。 本文提供了完整的系統(tǒng)設(shè)計說明和實現(xiàn)方法并對系統(tǒng)的運行情況作了充分的展示。 同時,本文還分析了實際移動網(wǎng)絡(luò)中的流量特征,從數(shù)據(jù)整體性、用戶行為特征、應(yīng)用特征和地理特征多個維度對流量進行了全面的分析,并對數(shù)據(jù)中的流量特征進行了說明和總結(jié)。
[Abstract]:Traffic engineering, also called traffic planning, is the problem of network operators' allocation and optimal utilization of network resources, including network planning, traffic measurement and analysis. Network control and optimization. The main problem solved by network traffic engineering is to optimize the overall performance of the network from the perspective of resources and traffic. From the perspective of resources, the main goal is to effectively manage network resources. Reasonable distribution of network load and utilization of network resources. From the point of view of traffic, the problems to be solved include reducing the delay, reducing the probability of packet loss, The most important idea of traffic engineering is to optimize the allocation of network traffic and improve the quality of service. Therefore, based on the idea of SDN/OF and the conditions provided, by using the related technology of complex network, this paper implements a traffic analysis system to solve the related problems in traffic analysis, including: reading data, establishing model, The characteristic indexes in the network are analyzed and the typical traffic analysis algorithm is implemented. This paper provides a complete system design description and implementation method, and the operation of the system is fully demonstrated. At the same time, this paper also analyzes the traffic characteristics of the actual mobile network, from the data integrity, user behavior characteristics, application characteristics and geographical features of multiple dimensions of the overall analysis of traffic. The characteristics of traffic in the data are explained and summarized.
