Problems solved by technology

The local cache in this method only provides external data, but the local cache data between clusters is difficult to maintain consistency, which is likely to cause business exceptions
Moreover, the database data between clusters may be inconsistent. If the data is restored from the database, it will cause abnormal business.

Embodiment Construction

[0058] The embodiments of this specification provide a method, device and medium for processing data of an SDN controller cluster.

[0059] The main responsibility of the SDN controller is to control the network of the data center, which plays a vital role in network operation and maintenance and the application of network resources. high demands. If the security and reliability of the controller in the network architecture cannot meet the requirements, it will affect the operation of the entire network, and in serious cases may directly lead to network paralysis.

[0060] Traditional software controller deployments are mostly single-node. However, a single controller has no active / standby guarantee, nor can it solve cross-regional SDN network problems, so it is necessary to introduce SDN controller cluster technology. A cluster-oriented SDN controller is superior to a single controller in terms of scalability, reliability, and performance. However, in the existing technolo...

Abstract

The embodiment of the invention provides an SDN controller cluster data processing method, which is used for solving the problems in the prior art that data synchronization is incomplete and database synchronization only depends on a controller. The method comprises the following steps: deploying a plurality of SDN controllers into an SDN controller cluster, wherein the SDN controller cluster comprises a main controller and a plurality of standby controllers; receiving a service request through a main controller, and processing the service request based on the main controller to obtain cache data and storage data; synchronizing the cached data to a standby controller according to a preset cache synchronization mechanism; and synchronizing the stored data to other relational databases in a database cluster through a pre-deployed synchronous mechanism of the relational databases in the database cluster.

Description

technical field [0001] This specification relates to the field of communication technologies, and in particular to a data processing method, device and medium of an SDN controller cluster. Background technique [0002] Software Defined Network (Software Defined Network, SDN) is a new network innovation architecture proposed by the CLeanState research group of Stanford University in the United States, and it is a way to realize network virtualization. Its core technology, OpenFlow, separates the control plane of network equipment from the data plane, thereby realizing flexible control of network traffic, making the network more intelligent as a pipeline, and providing a good platform for core network and application innovation. [0003] With the development of software technology, more and more software-defined network SDN technologies are used in data center networks and campus network environments. The SDN controller will deploy and monitor the core network, which requires...
