For convenience of description, the embodiment of the present invention is introduced according to a layered modular design, and fig. 2 is a schematic diagram of a system architecture provided by the embodiment of the present invention, as shown in fig. 2, mainly including: the system comprises a data layer, a network equipment layer, an irrigation service equipment layer, an information processing layer, an SDN controller and an interaction layer.
The SDN controller mainly manages and controls the network device in the network device layer through an OpenFlow protocol, and components such as a switch and a router in the network device layer need to support the OpenFlow protocol.
The SDN controller can be divided into a flow table control module and a network control module based on a northbound API according to functions; the network control module is used for communicating with a network equipment layer through an OpenFlow protocol; the flow table control module periodically acquires network information of an interaction layer according to bandwidth guarantee requirements, analyzes the current network condition, feeds back the current network condition to the interaction layer, transmits flow table adjustment information to a network equipment layer through the network control module, adjusts service network topology and optimizes service flow priority.
According to the embodiment of the invention, the SDN controller is added in the agricultural irrigation system, the centralized configuration of the network topology is realized through the SDN controller, and the human input generated by the reconfiguration of the network environment caused by equipment replacement or irrigation environment change is reduced.
The data layer is a storage device that manages data. The irrigation business equipment layer is a crop information collecting component (sensor) for irrigation and basic irrigation equipment for realizing irrigation business. The network device layer is the physical network device used to forward the data.
The information processing layer is divided into an irrigation information processing module and a network information processing module according to functions; the irrigation information processing module is used for acquiring irrigation information and acquisition information in the data layer and feeding back the irrigation information and the acquisition information to the interaction layer service information interaction module. The network information processing module is used for acquiring the network condition and the network topology information in the current service network and feeding back the network condition and the network topology information to the network information interaction module of the interaction layer.
The interaction layer is divided into a network information interaction module and a service information interaction module, the network information interaction module is used for feeding back current network topology information and network state information, and the corresponding network priority adjustment of the crop information collection component can be carried out through the network information interaction module; and the service information interaction module is used for feeding back the related information of the current basic irrigation equipment.
According to the specific embodiment of the present invention, the control of the network topology is implemented by communication between a flow table control module and a network control module in the SDN controller, specifically:
the flow table control module acquires a network topological structure of a network device layer through the network control module, the network control module directly acquires the network device layer device topological structure, namely the flow table control module initiates a flow table query request to the network control module, the network control module communicates with the switch and the router by using an OpenFlow protocol, acquires flow table information of the switch and the router and forwards the flow table information to the flow table control module, and the flow table control module acquires the network device layer topological information.
It can be understood that the network topology may be adjusted through the interaction layer, or may be adjusted through a preset adjustment algorithm or mechanism of the network topology.
Triggering a flow table calculation unit according to topology information when the adjustment operation of the network topology structure is finished or a certain time interval is set; the flow table calculation unit performs bandwidth guarantee calculation on the flow table according to the current flow table information, and the calculation result is transmitted to the flow table editing unit; the flow table editing unit performs operations such as adding or deleting on the flow table to adjust the flow table information; the flow table control module adjusts the flow table information and then sends the flow table information to the network control module, and the network control module communicates with the switch and the router in the network device by using the OpenFlow protocol to update the flow table information of the switch and the router.
According to the embodiment of the invention, in a specific application process, the identifier is adopted to guarantee the network bandwidth. For example, a large number of crop information collection components need to be deployed in a planting area a, and according to the number of the components, it is determined that sufficient bandwidth is needed to guarantee the stability of information forwarding, and then the identifier number of the crop information collection component in the planting area a is modified to 200 (within the range of 2-255), and meanwhile, if an identifier of a certain crop information collection component in another planting area B is also a priority identifier, but the priority identifier number is 100 and is lower than the priority identifier number 200 of the planting area a, bandwidth guarantee is configured for the planting area a with a high priority according to a higher proportion. The specific priority is determined according to the identifier of the crop information collection component, the initial identifier of each crop information collection component is a default identifier, and when the bandwidth guarantee requirement exists, the bandwidth guarantee can be realized by setting the priority of the identifiers on an interaction layer and adjusting the corresponding priority.
FIG. 3 is a schematic diagram of a bandwidth algorithm according to an embodiment of the present invention; as shown in the figure, in order to implement real-time bandwidth guarantee, the following algorithm is provided for the collection component participating in bandwidth guarantee.
After the available bandwidth is obtained, the actual required bandwidth of the current service cannot be determined, so that the actual required guaranteed bandwidth of the service is further calculated by adopting a successive approximation method, a flow table control module in the SDN controller periodically detects the actual flow in the service, if the current actual service flow is close to the current service guaranteed bandwidth and the current service guaranteed bandwidth is smaller than the service bandwidth guaranteed available bandwidth, the current service guaranteed bandwidth is increased, and if the current actual service flow is smaller than the current service guaranteed bandwidth, the current bandwidth is sufficient, so that the current service bandwidth is proved to meet the actual requirement.
Meanwhile, the flow table control module periodically detects the full-service bandwidth, reorders all the collection components participating in bandwidth guarantee according to the priority of the collection components, calculates the required service guarantee bandwidth again, and ensures the real-time effectiveness of bandwidth guarantee.
According to a specific embodiment of the present invention, the method further comprises: receiving an indication of adding network equipment sent by the user; responding to the user instruction, and determining whether to establish an independent data forwarding path according to the farmland type corresponding to the user instruction.
FIG. 4 is a flow diagram illustrating the addition of a new component in a network environment according to an embodiment of the present invention; FIG. 5 is a flow diagram illustrating removal of components in a network environment according to an embodiment of the present invention. In the actual irrigation environment, new test fields are temporarily reclaimed or crop information collection assemblies are temporarily added and deleted, and network equipment needs to be deployed or deleted. Such as: a crop information collection assembly from planting field B needs to be temporarily added to planting field a. Since these networks are temporary, a separate data forwarding path is not configured for the temporarily used in-plant crop information collecting component in the prior art, because the separate path exists for a short time and requires manpower to perform cumbersome routing and switch configuration, and after the priority is lowered, the network needs to use manpower to recover the configuration.
The specific implementation process is as follows: when the crop information collection assembly in the planting field B leaves the network, the flow table query unit periodically queries the current network topology structure, if the current network topology is found to be changed, the priority identifier of the leaving assembly is marked to be a stateless identifier, namely the priority identification number 0, the flow table calculation unit reads that the identifier of the path planting field terminal is the stateless identifier, the flow table editing unit is called to delete the path, the flow table adjustment information is issued to the network control module, and then the network control module sends the flow table adjustment information to a switch and a router of a network equipment layer through an OpenFlow protocol to update the network topology, so that the assembly networks can not access the service network in the planting field B any more.
The method comprises the steps that a flow table query unit in a planting field A queries a current network topology structure regularly, if the current network topology is found to be changed, a priority identifier of an added component is marked as a default identifier, namely a priority identification number 1, a flow table calculation unit reads a path planting field terminal identifier as the default identifier for the first time, a flow table editing unit is called to increase a flow forwarding path, default bandwidth guarantee is configured, flow table adjustment information is issued to a network control component, the flow table adjustment information is sent to a switch and a router of a network equipment layer through an OpenFlow protocol by a network controller, the network topology is updated, and the components can access a service network in the planting field A.
In some preferred embodiments of the invention, the method further comprises:
receiving an indication of adding network equipment sent by the user;
responding to the instruction of the user, and determining whether to establish an independent data forwarding path according to the farmland type corresponding to the instruction of the user;
if the farmland type is a test field, establishing an independent data forwarding path corresponding to the test field;
and determining the maximum bandwidth of the network equipment of the test field according to the total bandwidth of the network environment and the guaranteed bandwidth of the existing farmland network equipment.
Because a large amount of data may need to be collected in a test field to observe changes of crops, the data needs a large amount of bandwidth for transmission, and an independent data link is needed to ensure the confidentiality of the data, the invention realizes the establishment of an independent data forwarding path and bandwidth guarantee based on the SDN.
In some preferred embodiments of the present invention, for data obtained by a component in a field, the irrigation service equipment in the field is encrypted through a preset encryption configuration, and a specific implementation manner may be implemented by adding a heterogeneous accelerator card in an SDN controller.
When the SDN controller receives an instruction of a user to create a test field and sets the test field to be confidential, the SDN controller changes a network topology or adds a new path in the manner, and then encrypts data sent by irrigation service equipment in the test field through a heterogeneous accelerator card and a preset encryption configuration, wherein the encryption algorithm can be an encryption algorithm such as AES, which is not described herein any more.
Based on the same idea, some embodiments of the present application further provide a device and a system corresponding to the above method.
