The flow table is an abstraction of the data forwarding function of network devices by OpenFlow. In traditional network devices, the data forwarding of switches and routers needs to rely on the Layer 2 MAC address forwarding table or Layer 3 IP address routing table stored in the device, while OpenFlow The flow table used in the switch completes functions similar to traditional switches and routing.

Embodiment Construction

[0008] The implementation of the present invention is mainly through the task mode, the basic time period characteristics of the task and the statistical object and its combination, after the statistical task is created, the fixed object and the dynamic object are counted respectively, and the statistical result is calculated after the task period timer expires and passed Graphical display of statistical results and reports.

[0009] refer to figure 1 , the implementation steps of a method for realizing visualization of SDN flow table of the present invention include:

[0010] Step S101, statistical task creation, the system dynamically creates a statistical task context, including the statistical start time, end time, statistical cycle (can be seconds, 1 minute, 5 minutes, 10 minutes, 30 minutes, 1 hour, 24 hours, etc.) , the statistical objects include source IP address, source MAC address, source PORT number, destination IP address, destination MAC address, destination POR...

Abstract

The invention discloses a method for achieving visualization of an SDN flow table. A counter of the OpenFlow flow table is adopted as a basis, independent combination analysis and statistic counting are carried out on a static statistical object and a dynamic statistical object of the flow table based on statistics tasks and statistical objects input by a user, showing is achieved in real time in a graphical mode, maintenance personnel can know the internal state of the SDN flow table and the rule matching condition in real time, failures can be predicated fast, the failures can be fast located after the failures occur, and statistical data can powerfully support network planning in the future.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method for realizing visualization of an SDN flow table. Background technique [0002] Software-defined network is a new type of network innovation architecture. It is mainly composed of SDN controllers and OpenFlow switches. All control functions are centralized on remote SDN controllers, while OpenFlow switches are only responsible for simple and high-speed data forwarding locally. During the operation of the OpenFlow switch, the data forwarding basis is the flow table. The flow table is an abstraction of the data forwarding function of network devices by OpenFlow. In traditional network devices, the data forwarding of switches and routers needs to rely on the Layer 2 MAC address forwarding table or Layer 3 IP address routing table stored in the device, while OpenFlow The flow table used in the switch completes functions similar to traditional switches and routing. The f...
