基于SDN的网络流量管理系统

The system of network traffic management based on SDN

随着传统网络架构在日益增长的互联网用户和流量需求面前变得臃肿和难以满足需求,更先进的新型网络创新架构被提出并加以研究。提出基于SDN的网络流量管理系统,包括流量测量应用和路由优化应用。通过流量测量算法测量可用带宽、丢包率、链路抖动的服务质量(Quality of Service,QoS)参数,使用路由优化应用在多QoS约束条件下进行路径优化计算。在Mininet虚拟仿真网络测试下,该系统可以均衡地实现流量路由。

As the traditional network architecture becomes bloated and difficult to meet the demands of increasing Internet users and traffic,more advanced new network innovation architectures are proposed and studied.The system of network traffic management based on SDN networks is proposed,including traffic measurement applications and route optimization applications.The traffic measurement application measures the available bandwidth,packet loss rate,and Quality of Service(QoS)parameters for link jitter,and uses the routing optimization application to perform path optimization calculations under multiple QoS constraints.Under the Mininet virtual simulation network test,the system can achieve traffic routing in a balanced manner.
