SDN network equipment control plane management device and method

Abstract

A control plane management device for SDN network equipment, comprising an event detection module, an information reading module, a judging module, and a control plane management module, wherein the event detection module detects a control plane management trigger event, and judges the type of the control plane management trigger event ; When the event type of the control plane management trigger event is the first trigger event, the information reading module reads the first control plane information set of the SDN network device where the first trigger event occurs on the SDN controller, and reads the first trigger event The second control plane information set on the SDN network device of the event; the judging module judges whether the first control plane information set and the second control plane information set are consistent; the control plane management module compares the first control plane information set and the second control plane information set When the sets are inconsistent, send and delete the control plane information to the corresponding SDN network device. The invention also provides a method for managing the control plane of the SDN network equipment. The invention can improve the automation level, availability and reliability of the SDN system.

Description

technical field [0001] The present invention relates to the field of network communication, in particular to an SDN network equipment control plane management device and method. Background technique [0002] In the SDN network system, it mainly includes SDN management platform (such as SDN controller or management platform including SDN controller) and SDN network equipment (such as SDN switch). For SDN network equipment, there is SDN network equipment control plane information, its main Refers to the flow table in the SDN device or other flow control plane information, such as openflow flow table (flow table), ovsdb, etc. [0003] At present, in the SDN network system, there are still the following problems: 1. When the SDN network equipment is powered off or restarted, the SDN management platform cannot timely redeploy the control plane information of the SDN network equipment (that is, issue flow tables or other Control plane information), if not deployed in time, the SD...

AI Technical Summary

Problems solved by technology

[0003] At present, in the SDN network system, there are still the following problems: 1. When the SDN network equipment is powered off or restarted, the SDN management platform cannot timely redeploy the control plane information of the SDN network equipment (that is, issue flow tables or other Control plane information), if not deployed in time, the SDN network equipment will fail, which will affect network functions and performance; 2. When the SDN network equipment is directly modified by the user using local configuration methods such as CLI (flow table or other control plane information), and the SDN management platform is also required to redeploy the control plane information of SDN network devices in a timely manner

3. When the network environment of SDN network equipment such as neighbor connection relationship changes, the original control plane information may become invalid

At present these problems, prior art also does not have a kind of good solution
