【摘要】：流量工程,也可称为业务量规划,是网络运营商对网络资源的分配和优化利用的问题,一般包括网络规划,流量测量和分析,网络控制和优化。网络流量工程解决的主要问题是从资源和流量两个角度实现网络整体性能的优化。从资源的角度,主要目标是有效管理网络资源,合理分配网络负载和利用网络资源。从流量的角度,分析解决的问题包括：减少延时,降低丢包概率,提高网络吞吐量。流量工程最重要的思想就是通过各种技术实现全网流量的优化配置,提升网络的服务质量。因此,本文在依照SDN/OF的思想和所提供条件的基础上,利用复杂网络相关的技术,通过实现一个流量分析系统以解决流量分析中的相关问题。其中包括：读取数据,建立模型,分析网络中的特征指标,实现典型的流量分析算法,.提供丰富的数据和结果的可视化功能等。本文提供了完整的系统设计说明和实现方法并对系统的运行情况作了充分的展示。同时,本文还分析了实际移动网络中的流量特征,从数据整体性、用户行为特征、应用特征和地理特征多个维度对流量进行了全面的分析,并对数据中的流量特征进行了说明和总结。
[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.
