Problems solved by technology

[0003] However, the development of network function virtualization presents new challenges. This is because traditional network hardware has abundant traffic monitoring and display devices and network interfaces can be seen and touched on the hardware. The form of software or OpenFlow flow table runs on the data center node, and the network interface becomes invisible and intangible. At the same time, due to the characteristics of network virtualization, the network forwarding is completed by the OpenFlow flow table, which will not leave traces at the host system level , which also makes the visualization of network traffic difficult to achieve, and the user experience is poor
Moreover, since the network traffic cannot be visualized, the system administrator cannot visually observe the traffic between the virtual machines in the system, resulting in the inability to balance the scheduling of virtual machines to optimize the utilization of system resources, and also increase the difficulty of operation and maintenance

Abstract

The invention discloses a virtual network flow visualization method, device and equipment based on OpenFlow, and the method comprises the steps: firstly, issuing an OpenFlow flow table to a computing node Node to obtain virtual network flow information on the Node, then analyzing and summarizing the virtual network flow information on the Node to obtain processed virtual network flow information, and then judging whether the processed virtual network traffic exceeds a preset threshold value or not; and if yes, generating alarm information, using the alarm information for giving an alarm, and further, storing the processed virtual network flow information, so that a user can conveniently inquire the processed virtual network flow information. Therefore, the visualization of the virtual network traffic can be realized on the premise of not influencing the network performance, so that the user experience is improved, and the operation and maintenance difficulty is reduced.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to an OpenFlow-based virtual network flow visualization method, device and equipment. Background technique [0002] With the continuous development and improvement of network virtualization functions represented by software-defined networking and network function virtualization, more and more network functions in the data center that can only be realized by relying on traditional hardware are replaced by virtual network elements, and network function virtualization The development of virtualization is in line with the development trend of data centers and saves the hardware investment of data centers, and also greatly promotes the development of data center virtualization technology. [0003] However, the development of network function virtualization presents new challenges. This is because traditional network hardware has abundant traffic monitoring and display dev...
