Software-defined network sdn traffic monitoring and visualization system

Abstract

The invention relates to a software-defined network SDN flow monitoring and visualization system, the system includes a flow collection module, a flow distribution module, a visualization module and a server; the flow collection module is used to obtain port flow data and host flow data of SDN switches in each partitioned computer room , and the traffic data of the application flow, the traffic distribution module limits the speed according to the speed limiting mechanism. When M, then limit the speed of non-VIP hosts, then there is y^=M x; the visualization module is used to obtain the data in the database and visualize the data on three levels, and the present invention can realize the switch in the SDN system Flow monitoring, and to achieve flow speed limit control, in order to achieve the maximum utilization of flow.

Description

Technical field [0001] The present invention relates to the field of network traffic monitoring, and more particularly to a software-defined network SDN traffic monitoring and visualization system. Background technique [0002] SDN originated from the Clean Slate research topic of Stanford University in 2006. In 2009, Professor McKeown officially proposed SDN concept. With the hierarchical idea, SDN separates the data from the control phase. In the control layer, including logical centering and programmable controllers, you can master global network information, facilitate operators and researchers to manage configuration networks and deploy new protocols. In the data layer, including a dumb (DUMB) switch (unlike traditional Layer 2 switches, devices specifically for forwarding data). Switches only provide simple data forwarding capabilities to quickly handle the matching packets, adapt to the growing demand for traffic. Open unified interfaces (such as OpenFlow, etc.) are intera...

Problems solved by technology

[0003] For now, SDN still has some shortcomings. Under the traditional SDN system, the traffic distribution between different users is generally fixed, and the traffic distribution is carried out according to the broadband level opened by the user. During some peak hours of network usage, some The user's traffic has not reached its corresponding network speed, for example, a 200M wide user and a 50M wide user, in peak hours, the 50M wide user may have exceeded its network speed limit, while the 200M wide user is far from reach its corresponding network speed
