Fig. 1 is a block diagram of a server 100 according to an embodiment of the present invention. The server 100 includes a memory 110, a processor 120, and a communication module 130. The memory 110, the processor 120, and the communication module 130 are electrically connected to each other directly or indirectly to enable data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines.

For example, when the computer program stored in the memory 110 is executed by the processor 120, the video data transmission method disclosed in the following embodiments may be implemented.
The communication module 130 is used for establishing a communication connection between the server 100 and other communication terminals through a network, and for transceiving data through the network.
It should be understood that the configuration shown in fig. 1 is merely a schematic diagram of the configuration of the server 100, and that the server 100 may include more or fewer components than shown in fig. 1, or have a different configuration than shown in fig. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof.
Embodiments of the present invention further provide a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by the processor 120, the computer program implements the video data transmission method disclosed in the following embodiments.
Fig. 2 is a schematic flow chart of a video data transmission method according to an embodiment of the present invention. It should be noted that the video data transmission method according to the embodiment of the present invention is not limited by fig. 2 and the following specific sequence, and it should be understood that, in other embodiments, the sequence of some steps in the video data transmission method according to the embodiment of the present invention may be interchanged according to actual needs, or some steps may be omitted or deleted. The specific flow shown in fig. 2 will be described in detail below.
Step S201, after the sidecr component is started, receives video data of the video capture end through the DPDK virtual network card in the sidecr component.
In this embodiment, the server 100 includes a micro service module, and the micro service module is provided with a Sidecar component, and a corresponding DPDK virtual network card is deployed in the Sidecar component. The specific implementation process is as follows: firstly, a docker (container), kubernets and a DPDK environment are built, a DPDK physical network card on the server 100 is virtualized into a plurality of DPDK virtual network cards through a virtualization technology, and then the DPDK virtual network cards are loaded in a Sidecar assembly. When the Sidecar component is started, the DPDK virtual network card is bound, and the Sidecar component has kernel transceiving capacity and DPDK transceiving capacity. In addition, when the Sidecar component is started, the conventional Sidecar service functions such as service registration discovery, load, fusing and the like can be completed.
The Sidecar mode is non-intrusive, so that modification does not need business process perception, business logic is not affected, the whole cloud video processing related service can be validated by modifying the mode, and the development iteration speed is obviously improved by the traditional process modification mode. Therefore, compared with a mode that the implementation of the DPDK technology under the conventional software architecture needs to modify services related to all video streams (picture streams), for example, related service software such as a media gateway server, a picture gateway server, and an analysis server needs to be modified, in this embodiment, by loading the DPDK virtual network card in the Sidecar component, the network IO capability is improved, and meanwhile, the development iteration speed can be effectively improved.
Tests show that on the premise of only DPDK stream receiving reconstruction, the processing capacity of a single service can be improved to 2.8G/s from the original limit of 1.93G/s, and when 1.93G/s data is processed in the same way, CPU consumption is reduced by 1 core, the processing capacity is improved, the hardware cost of a video cloud is reduced, and the product competitiveness can be effectively improved.
Step S202, the video data is shared to the service process of the server by the Sidecar component in a memory sharing manner.
The shared memory is one of the ways of inter-process communication, and has better performance because the memory can be directly operated. After the Sidecar component is started and operated, the Sidecar component and the service process can communicate through a shared memory, and transmission of video data is achieved. Specifically, the sdvi module and the service process share the same memory area, and the microserver module writes the video data into the memory area through the sdvi module, so that the service process can read the video data from the memory area.
In this embodiment, the Sidecar component of the micro service module monitors the port through the DPDK virtual network card, and after receiving the video data, the video data may be shared to the service process of the server 100 in a memory sharing manner, so as to complete service processing such as storage and analysis of the video data through the service process. Taking the micro service module as the streaming media service as an example, the Sidecar component of the streaming media service receives video data through the DPDK virtual network card, and sends the video data to the streaming media service process in a memory sharing manner, and the service process performs service processing such as decapsulation and video parsing.
With video monitoring as a scene, thousands of cameras (namely the video acquisition end) are deployed in a certain urban area and used for road monitoring, criminal investigation and case solving and the like. Supposing that a suspect is wanted in the whole city, face recognition needs to be performed on video data acquired by ten thousand high-definition cameras at the cloud end, a 4MB high-definition code stream consumes 40GB bandwidth, the 40GB bandwidth generates very many interrupt processing at an inner core, and meanwhile, considerable performance is consumed by multiple data copying brought by an inner core processing mode. In this embodiment, the system changes the Sidecar component in the conventional socket mode into the Sidecar component in the DPDK + shared memory mode, which greatly improves the performance, and actually measures the data stream with the bandwidth of 4GB, thereby saving approximately 5 cores of CPU resources.
As can be seen, in the video data transmission method provided in the embodiment of the present invention, since the microservice module in the server 100 is provided with the sider component, and the sider component is disposed with the corresponding DPDK virtual network card, when the microservice module receives and sends the video data, the microservice module may receive the video data of the video acquisition end through the DPDK virtual network card in the sider component, and share the video data to the service process of the server 100 in a memory sharing manner through the sider component. Therefore, through the technologies of DPDK, shared memory and the like, the Sidecar component suitable for the video cloud is manufactured to receive and send video data, and compared with the Sidecar component in the traditional kernel socket mode, the network throughput capacity of the server 100 can be improved, the CPU resource consumption caused by network IO can be reduced, and the overall performance of the system is improved.
Optionally, in this embodiment, the micro service module and the Sidecar component communicate in a memory sharing manner. For example, when the micro service module is used as a sender service and needs to send a video, video data may be continuously shared to the Sidecar component in a memory sharing manner, and the Sidecar component sends the video data to a receiver service through the DPDK virtual network card.
Optionally, referring to fig. 3, the video data transmission method may further include:
and S301, sending the video data to other micro-service modules belonging to the same micro-service system as the micro-service module through a DPDK virtual network card in the Sidecar component.
Taking fig. 4 as an example, assuming that the microservice module in this embodiment is microservice a, when the microservice a needs to send video data to microservice B (other microservice modules) belonging to the same microservice system, the video data may be shared to the Sidecar component of the microservice a in a memory sharing manner, and the Sidecar component of the microservice a sends the video data to the microservice B through the DPDK virtual network card; the microservice B serves as a receiver of the video data, can receive the video data through a DPDK virtual network card of the Sidecar component, and can also send the received video data to other service processes on the service end in a memory sharing manner according to service requirements.
In this embodiment, the micro service module sends the video data to other micro service modules, so that the other micro service modules can perform corresponding processing on the video data. For example, for traffic video data, the micro service module may send the traffic video data to other micro service modules for identification processing, and determine whether a violation vehicle exists and identify the license plate number of the violation vehicle.
Optionally, referring to fig. 5, the video data transmission method may further include:
step S501, sending the video data to a device different from the server through the DPDK virtual network card in the Sidecar component.
In this embodiment, the microserver module may send the video data to another device for STORAGE or screen display through the DPDK virtual network card in the Sidecar component, where the other device may be a STORAGE device (STORAGE), a PC (Personal Computer), or the like as shown in fig. 6.
Optionally, referring to fig. 7, before step S201, the video data transmission method may further include:
step S701, receiving a flow receiving address acquisition request sent by a device access service module; the equipment access service module and the micro service module belong to the same micro service system.
Step S702, responding to the request for obtaining the stream receiving address, sending the stream receiving address to the equipment access service module, so that the equipment access service module sends the stream receiving address to the video acquisition end, and the video acquisition end sends the acquired video data according to the stream receiving address.
In this embodiment, the micro service system may further include a registry service module and a configuration center service module, and for all micro services in the micro service system, after being started, the registry service module completes routine operations such as registration and configuration information reading by the configuration center service module. When the equipment access service module acquires the stream receiving address from the micro service module, the equipment access service module inquires the address of the micro service module from the registration center service module and sends the stream receiving address acquisition request to the micro service module, and the micro service module responds to the stream receiving address acquisition request. And after the equipment access service module acquires the stream receiving address, the equipment access service module informs the video acquisition end of sending the acquired video data to the stream receiving address. Therefore, the micro-service module can receive the video data of the video acquisition end through the DPDK virtual network card in the Sidecar component.
It should be noted that, in this embodiment, the microserver module receives and transmits data in a DPDK + shared memory manner for the video request; for non-video messages, the original kernel network card mode can still be adopted to receive and transmit data due to relatively low network IO.
