Fig. 1 is a block diagram of a system structure according to an embodiment of the present invention, where the block chain network under the whole SDN architecture is classified according to the physical architecture of the SDN, and is mainly divided into 3 layers, namely an application layer, a control layer and a forwarding layer.
Application layer: the SDN application is an application program focused by a user, and can interact with the SDN controller through a northbound interface, namely, the applications can submit network behaviors required to be requested to the controller in a programmable mode, one SDN application can comprise a plurality of northbound interface drivers (using a plurality of different northbound APIs), meanwhile, the SDN application can abstract and package functions to provide a northbound proxy interface to the outside, and the packaged interface forms a higher-level northbound interface.
Control layer: an SDN controller, which is a logically centralized entity, is mainly responsible for two tasks, namely, converting SDN application layer requests to an SDN forwarding layer, and providing an abstract model (which may be state, event) of the underlying network for SDN applications. The control layer in the system is a distributed controller cluster composed of a plurality of controller entities.
And (3) a forwarding layer: the forwarding layer is made up of network-summarized physical switches, etc., that forward network traffic to their destinations.
In the whole system, the blockchain nodes are connected to a forwarding layer as users, and data among the blockchain nodes are forwarded, and the paths of the switches and the routers transmitted through the blockchain nodes are forwarded through the path planning diagram issued by the SDN controller, so that the deployment of the redundant controller is an important element in the whole system, the expandability of a system framework is ensured, and the safety and the reliability of a network are also ensured.
FIG. 2SDN architecture and blockchain correspondence:
in the system, the blockchain nodes are mainly divided into three types, namely a routing node, a consensus node and a common node. The main function of the corresponding routing node in the blockchain corresponds to the SDN architecture to serve as a controller, and the main functions of the common node and the common node correspond to the SDN architecture to serve as users, so that the related operation of the network in the SDN architecture is not participated. Therefore, in the system, the SDN controller is not only used as a controller for related operations such as routing protocol and path planning in the SDN architecture, but also used as a light node in the blockchain, and only synchronizes the blockhead information in the blockchain, and is mainly used for reducing hardware storage pressure and better completing storage of related information such as routing protocol and path planning.
Fig. 3 is an SDN controller deployment flow diagram: when the SDN network architecture is deployed, firstly, a network operator deploys the configured SDN controllers into corresponding physical links to form a distributed SDN controller architecture system. In the deployment process, for the safety of the network environment, the SDN controller needs to have a corresponding redundant controller as a standby, and the redundant controller is mainly generated by two methods:
first kind: when an operator deploys the whole SDN controller, corresponding standby controllers are correspondingly deployed to be used as redundant controllers in the network;
second kind: the blockchain node accessed to the SDN network architecture can be applied to become a redundant controller, and the blockchain node applied to become the redundant controller firstly has a requirement that the blockchain node has good network conditions and high-performance hardware equipment, and the blockchain node also only serves as a light node in the blockchain and is only used for storing the blockhead information of the blocks in the blockchain. After the block chain node reaches the corresponding standard, the block chain node can become a standby controller after verification of the corresponding controller.
After a corresponding problem occurs with the primary controller in the system, the standby controller becomes one of the primary controllers in the area and transmits data to the devices in the network in the area.
FIG. 4 is a block chain node application SDN redundancy controller flowchart; when the blockchain node applies to become an SDN redundant controller, firstly, the network condition of the blockchain node and the configuration condition of corresponding hardware equipment are required to be sent to the SDN controller of the corresponding area, the SDN controller in the corresponding area analyzes the data sent by the blockchain node, and when the verification accords with the basic equipment condition, the data is sent to other controllers in the area for verification.
The parameters of the verification include Bandwidth of the network, delay_time of the network, on-line Time length on_time, hardware device Hardware (storage and CPU, etc.), etc.
Each corresponding parameter corresponds to a threshold value, and the application condition can be reached only when the network condition and hardware equipment of the node exceed the corresponding configuration and threshold values.
The controller verification method mainly performs verification through a PBFT common method, when more than 2/3 controllers verify the application request passing through the blockchain node, the address of the blockchain node is stored in a neighbor node list of the controller, and a data packet containing TRUE information is returned to the blockchain node. And the SDN controller will package the corresponding SDN installation package and the like to the blockchain node, and synchronize the corresponding routing protocol and the corresponding information such as the path planning map. And installing the corresponding SDN installation package by the block chain link points, and synchronizing related information such as a routing protocol, a path planning diagram and the like corresponding to the controller.
After the block chain nodes synchronize the related data, the public key of the controller is used for signing and forwarding the installation Version number Version and the Hash value of the related routing protocol to the controller, so that the synchronization is completed.
