SDN新型网络架构业务流量监控研究

A Research of Traffic Flow Monitoring Based on SDA New Network Architecture

通过对SDN新型网络架构进行分析,对传统业务流量监控和基于SDN架构的业务流量监控进行比较。基于Mininet服务搭建了SDN新型网络架构流量监控环境,通过使用Mininet服务中的s Flow功能,将流量监控功能集中于控制器,实现了Agent对基础层交换机端口信息的报文提交和Collector对业务流量的全局监控和管理,并在此基础上进行了DDoS攻击模拟和防御验证。为深入研究SDN网络架构设计原理和进行SDN网络流量监控提供了理论和实践依据。

Based on the research of new network architecture of SDN,this paper compares traditional business traffic monitoring with the business traffic monitoring of SDN.Based on Mininet,a new SDN network architecture flow monitoring environment is built.By using the s Flow function in Mininet,the traffic monitoring function is concentrated in the controller. It implements message submission to base layer switch port with Agent and global monitoring and management of traffic flow with Collector. And DDoS attacks and defense verification are carried out. The research contents in this paper provide a theoretical and practical basis for further research on the design principles of SDN network architecture andcomplex network traffic monitoring.
