基于 Hadoop 平台的网络流量分析系统的设计与实现 Design and Implementation of Network Traffic Analysis System Based on Hadoop Platform摘 要为了解决网络使用过程中产生恶意流量而影响用户体验及网络安全的问题，设计了网络流量分析系统。应用了离线数据分析的方法，采用Hadoop 生态系统、WireShark 捕获报文工具和数据可视化图表完成了对TCP/IP 协议网络流量进行储存和分析的设计。在 Windows 系统和Hadoop 平台相结合的环境下进行了开发实现，结果表明：该系统能够解决恶意流量对网站或企业内网造成安全影响及网络资源占用的问题，具有可直接观测流量走势和存储大小可扩展的优势。关键词：Hadoop；网络安全；恶意流量；网络流量分析AbstractIn order to solve the problem that the user experience and network security are affected by the malicious traffic in the process of network use, a network traffic analysis system is designed. The design of TCP/IP network traffic storage and analysis is completed by using the method of offline data analysis, Hadoop ecosystem, WireShark capturing message tool and data visualization chart. The results show that the system can solve the problems of malicious traffic causing security impact on websites or intranets and occupying network resources. It has the advantages of direct observation of traffic trends and scalability of storage size.Key words： Hadoop；Network security；Malicious traffic；Network traffic analysis目 录第一章 课题绪论............................................................................................11.1 研究背景和意义介绍..........................................................................11.2 网络流量及网络攻击..........................................................................11.3 研究现状..............................................................................................31.4 论文结构安排......................................................................................3第二章 相关背景技术....
