Control plane management apparatus and method for SDN network device

Abstract

The invention discloses a control plane management apparatus for an SDN network device. The apparatus comprises an event detection module, an information reading module, a judgment module and a control plane management module, wherein the event detection module detects a control plane management triggering event and judges the type of the control plane management triggering event; the information reading module reads a first control plane information set of the SDN network device with an SDN controller on which a first triggering event occurs, and reads a second control plane information set on the SDN network device in which the first triggering event occurs, when the event type of the control plane management triggering event is the first triggering event; the judgment module judges whether the first control plane information set is consistent with the second control plane information set or not; and the control plane management module performs control plane information issuing and deletion on the corresponding SDN network device when the first control plane information set is inconsistent with the second control plane information set. The invention furthermore provides a control plane management method for the SDN network device. According to the method and the apparatus, the automation level, availability and reliability of an SDN system can be improved.

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...

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
