Embodiment 1
[0035] The embodiment of the present invention provides a data interaction method between internal containers of the power edge IoT agent, such as figure 1 shown, including the following steps:
[0036] Step S1: Set up the virtual switch management module in the user state of the operating system running on the edge IoT agent, and pre-define the functions of the virtual switch.
[0037] In the embodiment of the present invention, the Linux operating system running on the edge IoT agent is divided into a user state and a kernel state, and a virtual switch management module is set in the user state to predefine functions of the virtual switch. The management functions provided by the virtual switch management module include: enabling and disabling virtual ports, forwarding rule setting, port mirroring, MAC address management, virtual switching label management, virtual network card management, packet statistics and traffic management, etc. The management APP can flexibly adjust...
Embodiment 2
[0051] An embodiment of the present invention provides a terminal, such as Image 6 As shown, the device may include a processor 51 and a memory 52, wherein the processor 51 and the memory 52 may be connected via a bus or in other ways, Image 6 Take connection via bus as an example.
[0052] The processor 51 may be a central processing unit (Central Processing Unit, CPU). The processor 51 can also be other general-purpose processors, embedded microcontrollers (Embedded MCU, such as microcontrollers with architectures such as ARM and PowerPC), digital signal processors (Digital Signal Processor, DSP), application specific integrated circuits (Application Specific Integrated Circuit , ASIC), Field-Programmable Gate Array (Field-Programmable GateArray, FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components and other chips, or a combination of the above-mentioned types of chips.
[0053] As a non-transitory computer-re...

Abstract
The invention discloses a data interaction method between internal containers of an electric power edge Internet-of-things agent, comprising the following steps of: running a user mode of an operatingsystem on the edge Internet-of-things agent to set a virtual switch management module, and performing function pre-definition on a virtual switch; loading a predefined virtual switch in a kernel modeof the operating system to form a data exchange network between the containers; creating at least one virtual network card for each container by the virtual switch, and using at least one physical communication port as a communication port of the virtual switch; performing port learning according to a preset information group by the plurality of virtual ports; generating a forwarding lookup tablefor subsequent message forwarding according to a preset forwarding rule, according to the method, the network data packet can be accurately identified and managed, and secondary packaging is carriedout by adopting a self-defined security protocol, so that the security of network interaction data is enhanced, the isolation strength between containers is improved, an original APP can directly runwithout modifying a TCP/IP protocol communication code, and the compatibility of the APP is ensured.
Description
technical field [0001] The invention relates to the technical field of electric power communication, in particular to a data interaction method between internal containers of an electric power edge IoT agent. Background technique [0002] Edge computing is to transfer data processing, application running and other functions from the cloud computing center to the edge nodes of the network. Taking the intelligent power distribution system as an example, the power distribution protection algorithm requires the system to have real-time response capabilities. If the data is transmitted to the cloud computing center for centralized calculation, the response speed will not meet the demand. At the same time, the measurement and control device will also generate a large amount of data, which contains a lot of useless data. If these data are transmitted to the cloud computing center for calculation, it will put a lot of pressure on the network transmission, and the actual value is no...
