Taking a scheduling controller as an example, one flow of the media forwarding service scheduling method includes:
201. and acquiring service requirement information of the terminal equipment, wherein the service requirement information comprises first position information and quantity information of the terminal equipment.
The scheduling controller acquires service requirement information of the terminal equipment, wherein the service requirement information comprises first position information and quantity information of the terminal equipment. Specifically, the media service management subsystem of the scheduling controller acquires the first position information of the terminal device from the terminal access position information subsystem, and the media service management subsystem can acquire the first position information at regular time or acquire the first position information based on the trigger instruction, which is not limited in detail.

In the example shown in fig. 3, after the terminal device accesses the terminal access subsystem of the scheduling controller, the location information acquisition SDK of the terminal device sends a location information reporting request to the terminal access subsystem, where the location information reporting request carries the IP address of the terminal device. After receiving the position information reporting request, the terminal access subsystem forwards the position information reporting request to the terminal access position information subsystem, and the terminal access position information subsystem acquires and stores the IP address of the terminal equipment from the position information reporting request so that the scheduling controller can make a subsequent scheduling decision of the media forwarding service.
202. And determining first scheduling information of the media forwarding node according to the service demand information, wherein the first scheduling information comprises the capacity and the deployment area of the media forwarding node.
The scheduling controller determines first scheduling information of the media forwarding node according to the service demand information, wherein the media forwarding node is used for providing media forwarding service for the terminal equipment, the first scheduling information comprises capacity of the media forwarding node and deployment areas, the capacity comprises the number of the terminal equipment which the media forwarding node supports to be accessed, and the deployment areas comprise deployment positions of the media forwarding node.

The scheduling controller may further determine the first scheduling information of the media forwarding node according to the service requirement information and an operation cost of the media forwarding node or a service level agreement SLA of the terminal device.
Referring to fig. 4, fig. 4 is a schematic flow chart of determining first scheduling information by a scheduling controller according to service requirement information according to an embodiment of the present application. In the example shown in fig. 4, the media service management subsystem of the scheduling controller decides the deployment area, type and capacity of the media forwarding node according to the location information, the number information of the terminal devices, the operation cost of the media forwarding node, the service range or the service protocol level of the terminal devices. Specifically, before the deployment information is decided, the media service management subsystem of the scheduling controller is pre-configured with information such as the service forwarding operation cost of the Iaas service provider SP, the Iaas resource access location range, the service forwarding operation cost of the Saas service provider, the service forwarding access location range and the like. In step 2a, the scheduling controller obtains the location information of the terminal device, counts the number information of the terminal device according to the location information by area, and determines the deployment area, type and capacity of the media forwarding node by combining the location information of the terminal device, the operation cost of the media forwarding service and the access location range of the media forwarding service.

And 2, deciding the type of the media forwarding node deployed in the second area as a third-party media forwarding node by the scheduling server.
In the example shown in fig. 4, the scheduling controller decides the deployment capacity of the media forwarding node. For example, in case 1, the scheduling controller decides to add an own media forwarding node deploying the corresponding capacity in the first area. In case 2, the decision is made to reduce the deployment of the own media forwarding node of the corresponding capacity in the first area. Specifically, in step 2b, when the own media forwarding node with the corresponding capacity is deployed in an increased or decreased manner, the application for obtaining the own forwarding service Iaas resource is required.
In the example shown in fig. 4, after the media service management subsystem of the scheduling controller decides the deployment area, type, and capacity of the media forwarding node, the media service management subsystem updates the registration information of the media service information subsystem based on the decision result. For example, in step 2e, the media service management subsystem updates and stores information such as type, provider, capacity and price of the media forwarding node in the corresponding area in the media service information subsystem. In some alternative embodiments, when the service requirement information of the terminal device changes, the scheduling controller updates the first scheduling information according to the changed service requirement information. According to the embodiment of the invention, the scheduling server can dynamically adjust the deployment decision of the media forwarding node based on the real-time service requirement of the terminal equipment, so that the real-time performance of the deployment decision is improved.

203. And the terminal equipment sends a service request to the scheduling controller, wherein the service request carries the second position information.
The terminal device sends a service request to the scheduling controller, wherein the service request carries second position information of the terminal device. The service request is for requesting media forwarding service resources from the scheduling controller.
Referring to fig. 5, fig. 5 is a schematic diagram of a scheduling flow of a terminal device according to an embodiment of the present application. In the example shown in fig. 5, in step 3a, the video monitoring service management SDK of the terminal device initiates a video monitoring viewing request to the scheduling controller, in step 3b, the terminal access subsystem of the scheduling controller forwards the video monitoring viewing request to the video monitoring service management subsystem, and in step 3c, the video monitoring service management subsystem applies for a media forwarding service resource to the media service scheduling subsystem.
204. And determining second scheduling information of the terminal equipment according to the second position information, wherein the second scheduling information comprises an access address of a media forwarding node to which the terminal is to be accessed.
The scheduling control determines second scheduling information of the terminal equipment according to the second position information, wherein the second scheduling information comprises an access address of a media forwarding node to which the terminal equipment is to be accessed. The second scheduling information further includes a type of media forwarding node to which the terminal device is to access.
Specifically, the scheduling controller obtains media service information according to the second location information, where the media service information includes provider information, operation cost, network quality of service Qos information and remaining capacity of the second location and media forwarding nodes adjacent to the second location. The scheduling server determines second scheduling information of the terminal equipment in combination with the media service information, the service level agreement SLA or the equipment capability of the terminal equipment. The device capabilities of the terminal include supported video bandwidth, media acceleration hardware information, or the ability to support access to third party media forwarding nodes.
In the example shown in fig. 5, after the media service scheduling subsystem of the scheduling controller receives the application for the media forwarding service resource as in step 3c, the media service scheduling subsystem acquires media service information from the media service information subsystem based on the access location information of the terminal device as in step 3 d. And determining second scheduling information of the terminal equipment according to the media service information, the service level agreement SLA combined with the terminal equipment, the single equipment access price or the equipment capacity. The second scheduling information includes whether the type of the media forwarding node to be accessed by the terminal device is an own media forwarding node or a third party media forwarding node, and an access address of the media forwarding node to be accessed by the terminal device. For example, in step 3e, the media service scheduling subsystem schedules the terminal device to access the own media forwarding service node, and in step 3e', the media service scheduling subsystem schedules the terminal device to access the third party media forwarding service node. In step 3f, the media service scheduling subsystem returns second scheduling information to the video monitoring service management subsystem, and in step 3g, the scheduling controller video monitoring service management subsystem sends an access notification of the media forwarding service node to the terminal access subsystem of the scheduling controller, the access notification includes the second scheduling information, and the terminal access subsystem sends the media forwarding service notification to the terminal device.
In this embodiment of the present application, before the scheduling controller determines the second scheduling information of the terminal device according to the second location information, the scheduling controller receives network Qos information sent by the terminal device, where the network Qos information includes Qos information collected by the terminal device or predicted Qos information, and the network Qos information includes delay, packet loss rate, or jitter.
Referring to fig. 6, fig. 6 is a flow chart of media service Qos information feedback according to an embodiment of the present application. In the example shown in fig. 6, in step 4a, the media service Qos acquiring SDK of the terminal device acquires Qos information of the media forwarding node, and the specific media service Qos acquiring SDK may acquire Qos information of the media forwarding node at regular time or based on a trigger instruction. And the media service Qos acquisition SDK of the terminal equipment sends Qos information to a terminal access subsystem of the scheduling controller. In step 4b, the terminal access subsystem forwards Qos information to the media service Qos acquisition subsystem. In step 4c, the media service Qos subsystem updates Qos information of the corresponding media forwarding node, and sends the updated Qos information to the media service information subsystem.
205. And sending the second scheduling information to the terminal equipment.
The scheduling controller sends second scheduling information to the terminal equipment, and the terminal equipment accesses the corresponding media forwarding node based on the second scheduling information. Specifically, after the media service scheduling subsystem of the scheduling controller determines the second scheduling information, the second scheduling information is sent to the video monitoring service management SDK of the terminal device through the video monitoring service management subsystem and the terminal access subsystem. After the video monitoring service management SDK of the terminal equipment receives the second scheduling information, the media forwarding service SDK dynamic scheduling framework of the terminal equipment schedules the self forwarding service SDK to access the self media forwarding node based on the second scheduling information, or the media forwarding service SDK dynamic scheduling framework schedules the third party forwarding service SDK to access the third party media forwarding node based on the second scheduling information.
In the example shown in fig. 5, in step 3h, the terminal device receives the second scheduling information sent by the scheduling controller. In step 3i, the media forwarding service SDK dynamic scheduling framework of the terminal device invokes the own forwarding service SDK or the third party forwarding service SDK based on the access notification of the media forwarding service, and if the terminal device does not have a corresponding SDK locally, the media forwarding service SDK dynamic scheduling framework dynamically loads the corresponding SDK. The self forwarding service SDK is used for accessing the terminal equipment to the self media forwarding node, and the third party forwarding service SDK is used for accessing the terminal equipment to the third party media node. For example, in step 3j, the media forwarding SDK dynamic scheduling framework invokes the own forwarding service SDK, and in step 3k, the terminal device accesses the own media forwarding service node. In step 3j ', the media forwarding SDK dynamic scheduling framework invokes the third party forwarding service SDK, and in step 3k', the terminal device accesses the third party media forwarding service node.
The scheduling server in the embodiment of the invention can also determine the media forwarding node accessed by the terminal equipment according to the service request sent by the terminal equipment, thereby improving and reducing the access cost of the terminal equipment for accessing the media forwarding node.
