It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The existing cloud game is designed and deployed by self-building a machine room by each game manufacturer and locally deploying a game server in the machine room. It is difficult to satisfy large-scale cloud game service scenarios with only a few local servers. In view of the technical problem, in the embodiment of the application, the picture rendering task is handed to the cloud server, and the cloud server completes the picture rendering by means of the independent rendering resource pool, so that the picture rendering task is moved to the cloud, the advantages of cloud resources are fully utilized, the picture rendering efficiency is improved, the requirement of a large-scale picture rendering scene can be met, and a large-scale game scene can be met.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a cloud network system according to an exemplary embodiment of the present disclosure; as shown in fig. 1, the cloud network system 100 includes: terminal device 101, cloud server 102, and rendering resource pool 103 independent of cloud server 102. Wherein rendering resource pool 103 includes at least one rendering resource. The rendering resources may be any hardware module, chip, or device with screen rendering capabilities, such as but not limited to a GPU chip, a terminal device with a GPU, a server with a GPU, or the like.
In the present embodiment, the number of terminal apparatuses 101 is not limited, and is generally plural. The terminal device 101 may be any device having communication capability and screen display capability, and may be, for example, a smart phone, a tablet computer, a desktop computer, a wearable device, a game console, or the like. In contrast to the physical server, the cloud server 102 is actually a service platform deployed in the cloud and capable of providing comprehensive business capability for various internet users, and various resources supported by the service platform can be flexibly allocated. In this embodiment, the cloud server 102 may provide a screen rendering service to the terminal apparatus 101.
When the terminal device 101 needs to display a screen, a screen rendering request may be sent to the cloud server 102 to request the cloud server 102 to render a required screen for the terminal device. The picture rendering refers to a process of projecting an object model in a two-dimensional or three-dimensional scene into a two-dimensional digital image according to set environment, light, material and parameters. Wherein, the model is the description of two-dimensional or three-dimensional object by using data structure, which comprises the information of geometry, viewpoint, texture, etc.
For the cloud server 102, a picture rendering request sent by the terminal device 101 may be received, and picture content to be rendered adapted to the terminal device 101 is generated according to the picture rendering request; thereafter, the screen content to be rendered may be provided to the rendering resource pool 103 for rendering. The rendering resource pool 103 may receive the to-be-rendered picture content provided by the cloud server 102, perform rendering operation on the to-be-rendered picture content by using the rendering resource of the to-be-rendered picture content, and transmit the rendered picture to the terminal device 101. The terminal device 101 receives and displays the screen transmitted from the rendering resource pool 103.
In this embodiment, the picture rendering task of the terminal device 101 is handed to the cloud server 102, and the cloud server 102 completes the picture rendering by means of the independent rendering resource pool 103, so that the picture rendering task is moved to the cloud, the advantages of cloud resources are fully utilized, the picture rendering efficiency is improved, and the requirements of large-scale picture rendering scenes, such as large-scale game scenes, can be met.
Further, in the present embodiment, the cloud server 102 is not responsible for performing a specific screen rendering operation, but performs a screen rendering operation by using rendering resources in the rendering resource pool 103. This reduces the requirements on the cloud server 102, and the cloud server 102 may not need rendering resources, which is beneficial to reducing the implementation cost of the cloud server 102.
In some embodiments of the present application, as shown in fig. 1, at least one simulator 104 for screen rendering is running on the cloud server 102. The simulator 104 mainly refers to software for simulating a function of a hardware processor and a program of an instruction system through software, so that the cloud server 102 can run software of an application server with a screen rendering function provided by another platform. The cloud server 102 may provide various screen rendering services to the terminal apparatus 101 by means of at least one simulator 104. In other words, at least one simulator 104 is run on the cloud server 102, and for any simulator 104, in response to a picture rendering request from a corresponding application sent by the terminal device 101, the picture content to be rendered adapted to the terminal device 101 is generated according to the picture rendering request; thereafter, the screen content to be rendered may be provided to the rendering resource pool 103 for rendering. The simulator 104 of the present embodiment is functionally different from an android (android) simulator in the existing solution, and the simulator 104 of the present embodiment gives a specific screen rendering task "remote" to the rendering resource pool 103.
Further, the simulator 104 of the present embodiment is also different from an android (android) simulator in the existing solution in terms of deployment implementation. In the embodiment of the present application, the simulator 104 may be deployed in a Virtual Machine (VM) 105 on the cloud server 102, as shown in fig. 1. To achieve isolation between different simulators 104, a simulator 104 may be deployed in a virtual machine 105. The virtual machine refers to a complete computer system which has complete hardware system functions and runs in a completely isolated environment through software simulation. Further, the cloud server 102 may employ a Virtual Machine Monitor (or hypervisor)106 to manage at least one simulator 104 to adapt to the cloud environment. The hypervisor is system software, can maintain a plurality of virtual machines, and can allocate a proper amount of resources such as a memory, a CPU, a disk and the like to each virtual machine.
For example, in some embodiments, the cloud server 102 employs an L inux operating system, and the VM on the cloud server 102 is implemented Based on a L inux Kernel, which may be abbreviated as KVM (Kernel-Based Virtual Machine), and correspondingly, the hypervisor on the cloud server 102 may be abbreviated as KVM.
Specifically described herein are: in the embodiment of the present application, instead of directly moving an android (android) simulator in the existing scheme to the cloud server 102, the simulator 104 whose function and implementation are different from those of the android simulator is redeployed on the cloud server 102. This is because the android simulator operates based on hypervisor, and the cloud server 102 manages applications or services thereon by using the VM as a carrier and manages the VM by using hypervisor technology, and if the android simulator directly operates inside the VM, which is equal to the nested virtualization technology, the efficiency of rendering the picture is reduced, or even the performance requirement cannot be met.
In the embodiments of the present application, an implementation manner in which the cloud server 102 provides the screen content to be rendered to the rendering resource pool 103 is not limited. For example, the cloud server 102 may provide a storage space for the rendering resource pool 103, store the to-be-rendered screen content in the storage space, and notify the rendering resource pool 103 to read the to-be-rendered screen content in the storage space. For another example, the cloud server 102 may also transmit the screen content to be rendered to the rendering resource pool 103 based on a network channel between the cloud server and the rendering resource pool 103. The cloud server 102 and the rendering resource pool 103 may be connected via a network.
In the embodiment of the present application, a network transmission protocol adopted by a network channel between the cloud server 102 and the rendering resource pool 103 is not limited. For example, the network Transmission Protocol adopted by the network channel may be, but is not limited to, a Transmission Control Protocol/Internet Protocol (TCP/IP) or a Remote Direct Access Protocol (RDMA), that is, the cloud server 102 may transmit the picture content to be rendered to the rendering resource in the rendering resource pool 103 through the TCP/IP Protocol or the RDMA Protocol, so as to perform Remote rendering on the rendering resource in the rendering resource pool 103.
It should be noted that, in the rendering resource pool 103, a resource manager may be operated, and is responsible for managing and scheduling rendering resources in the rendering resource pool 103, so as to improve the utilization rate of the rendering resources and ensure the image rendering efficiency. In this embodiment, the manner in which the resource manager manages and schedules rendering resources in the rendering resource pool 103 is not limited. For the rendering resources in the rendering resource pool 103, after receiving the to-be-rendered picture content transmitted by the cloud server 102 through the network channel, the to-be-rendered picture content may be rendered to render a picture required by the terminal device 101. Further, before the rendered pictures are transmitted to the terminal device 101, the rendered pictures may be encoded into video streams of various video formats such as H264 or H265; the video stream is then transmitted to the terminal device 101 through the network. For the terminal device 101, a video stream transmitted by a rendering resource in the rendering resource pool 103 may be received through a network, and the video stream is decoded to obtain a picture and the picture is displayed. It should be noted that, in addition to providing the content of the picture to be rendered to the rendering resource pool 103, the cloud server 102 also provides the rendering resource pool 103 with information related to the terminal device 101, such as a MAC address, an IP address, and user information corresponding to the terminal device 101, which ensure that the rendering resource pool 103 successfully transmits the picture to the terminal device 101 after successfully rendering the picture.
It should be noted that the cloud network system capable of moving the picture rendering task to the cloud provided in the embodiment of the present application may be applied to various application scenes that need to perform picture rendering, for example, some 3D drawing scenes, some video playing scenes, game scenes, and the like. In the following embodiments of the present application, cloud game scenes are taken as an example for explanation.
Fig. 2 is a schematic structural diagram of a cloud game system according to an exemplary embodiment of the present disclosure; as shown in fig. 2, the cloud game system 200 includes: game terminal 201, cloud server 202, and GPU resource pool 203 independent of cloud server 202. The GPU resource pool 203 includes at least one GPU resource, and the GPU resource may be a GPU chip, a terminal device with a GPU, or a server with a GPU resource.
In the embodiment of the present application, the game terminal 201 may be any computer device with communication capability and screen display capability, for example, a smart phone, a tablet computer, a desktop computer, a game console, and the like. Wherein, the user can play the cloud game through the game terminal 201.
In this embodiment, considering that the local server generally cannot satisfy the large-scale cloud game service scenario, the cloud game is moved to the cloud, that is, the cloud game is operated on the cloud server 202, so that the advantages of adjustability of cloud resources, large resource amount and the like can be fully utilized, and the requirement of the large-scale cloud game service scenario is satisfied.
Moving the cloud game to the cloud means that tasks such as rendering and compressing images in the cloud game need to be moved to the cloud, and the tasks need to be completed by using computing resources such as a GPU. Certainly, the cloud server 202 may have computing resources such as a GPU, but it is considered that the cloud server with the computing resources such as the GPU is generally expensive and cannot be borne by many game manufacturers, which is also a difficult problem in the cloud relocation process of the cloud game at present. In this embodiment, in the cloud game system 200, the GPU resource pool 203 independent of the cloud server 202 is provided, the GPU resource pool 203 is independent, services such as image rendering, compression, transmission and the like are provided for the cloud server 202, and the cloud server 202 can be freed from expensive cost, so that it is possible to move the cloud game to the cloud.
Although the cloud server 202 may perform operations such as rendering, compressing, and transmitting pictures for the cloud game using the GPU resource pool 203, the cloud server 202 is not necessarily provided with its own computing resources such as GPUs.
Based on the above, when the cloud game screen needs to be displayed, the game terminal 201 may send a screen rendering request to the cloud server 202, where the request carries information such as an identifier of the game terminal 201, an identifier of the cloud game, and an identifier of the cloud game screen that needs to be rendered. The cloud server 202 receives the picture rendering request sent by the game terminal 201, generates game content to be rendered, which is adapted to the game terminal 201, according to the picture rendering request, and provides the game content to be rendered to the GPU resource pool 203 for rendering. The GPU resource pool 203 may render the game content to be rendered to obtain a game screen required by the game device 201; the game screen is transmitted to game terminal 201, so that game terminal 201 can display the game screen. Optionally, after rendering the game screen by the GPU resource pool 203, encoding the game screen into a video stream in a format of H264 or H265, and transmitting the video stream to the game terminal 201 through the network; the game terminal 201 receives the video stream, decodes the video stream to obtain a game screen, and displays the game screen.
In some optional embodiments of the present application, a game simulator 204 may be deployed on the cloud server 202, where the game simulator 204 is a simulator developed by researching package contents of a game client and a server, and is capable of enabling the cloud server 202 to simulate a network game server. With the aid of the game simulator 204, the cloud server 202 can simulate a network game server, providing connection and game services for the network game client. The encapsulation refers to a process of transmitting a specified data packet in a network by using a specified protocol.
In the embodiments of the present application, the cloud server 202 may provide a variety of game services to the game terminal 201 by means of the game simulator 204. In other words, the game simulator 204 is run on the cloud server 202, and for any simulator 104, the game content to be rendered that is adapted to the game terminal 201 may be generated according to the screen rendering request received from the game terminal 201, and the game content to be rendered is provided to the GPU resource pool 203 for remote rendering.
In some application scenarios, a user needs to play a game under an android system (abbreviated as an android game) through the game terminal 201, in these application scenarios, an android simulator may be run on the cloud server 202, for the android simulator, a screen rendering request sent by the game terminal 201 may be received, and according to the screen rendering request, an instruction of an Open Graphics library (OpenG L for Embedded Systems, OpenG L ES) of the Embedded system is generated and remotely transmitted to a GPU resource in the GPU resource pool 203 for remote rendering, where the Open Graphics library (OpenG L) is a cross-programming language, cross-platform Graphics program interface for rendering 2D and 3D vector Graphics, the OpenG L ES is a subset of the OpenG L and is designed for Embedded devices such as a mobile phone, a tablet computer, a game host, and the like.
Further, in the present embodiment, considering that the cloud server 202 performs screen rendering using an external GPU resource pool, in order to improve transmission efficiency, the instructions may be remotely sent to the GPU resource pool through a high-speed network channel between the cloud server and the rendering resource pool 103 for remote rendering. The network transmission protocol adopted by the network channel can be, but is not limited to, a TCP/IP protocol or an RDMA protocol.
In this embodiment, the cloud server 202 may employ a kernel-based virtual machine 205 as a carrier to carry various services thereon. Among them, the android simulator, as a service on the cloud server 202, also needs to be carried by a virtual machine. In other words, the cloud server 202 has the virtual machine 205 deployed thereon, and the android simulator can run in the virtual machine 205. However, in the prior art, the android simulator directly runs on the server, and the running is completed based on a hardware acceleration Execution Manager (hadm), which already adopts the hypervisor technology. If the android simulator in the prior art is directly moved to the virtual machine 205 on the cloud server 202 for implementation, which is equal to nested virtualization, the operation efficiency is low, and the performance requirement cannot be met. Based on this, the android simulator in the embodiment of the application is an android simulator which is self-developed and adapted to a virtual machine technology, and is not directly used in the prior art, the android simulator in the embodiment of the application is different from the android simulator in the prior art in functions and deployment, and the android simulator in the embodiment of the application is adapted to a cloud environment, so that the running efficiency is high.
In the embodiment, by utilizing the advantages of adjustability of resource elasticity, large resource amount and the like of the cloud server, a plurality of game simulators can be deployed on the cloud server, so that the number of the game simulators can be remarkably increased, and the requirements of large-scale game service scenes are met. Furthermore, the independent GPU resource pool is used for performing centralized rendering on each game picture, so that the realization cost of cloud relocation of the cloud game can be reduced.
In addition, the present application also provides a screen rendering method, which is described in the following embodiments from the perspective of a cloud server.
Fig. 3 is a schematic flowchart of a screen rendering method according to an exemplary embodiment of the present disclosure; applicable to a cloud server, as shown in fig. 1, the method includes:
31. receiving a picture rendering request sent by terminal equipment;
32. generating to-be-rendered picture content adaptive to the terminal equipment according to the picture rendering request;
33. and providing the content of the picture to be rendered to a rendering resource pool independent of the cloud server, so that the rendering resource pool renders the picture required by the terminal equipment and sends the picture to the terminal equipment for display.
In this embodiment, the number of terminal devices is not limited, and is generally plural. The terminal device may be any device having communication capability and having a screen display requirement, and may be, for example, a smart phone, a tablet computer, a desktop computer, a wearable device, a game console, or the like. In contrast to the physical server, the cloud server 102 is actually a service platform deployed in the cloud and capable of providing comprehensive business capability for various internet users, and various resources supported by the service platform can be flexibly allocated. In this embodiment, the cloud server may provide a screen rendering service to the terminal device. The picture rendering refers to a process of projecting an object model in a two-dimensional or three-dimensional scene into a two-dimensional digital image according to set environment, light, material and parameters. Wherein, the model is the description of two-dimensional or three-dimensional object by using data structure, which comprises the information of geometry, viewpoint, texture, etc. Based on the above, when the terminal device needs to display a screen, a screen rendering request may be sent to the cloud server to request the cloud server to render a required screen for the terminal device.
For the cloud server, a picture rendering request sent by the terminal equipment can be received, and picture content to be rendered, which is adaptive to the terminal equipment, is generated according to the picture rendering request; and then, the picture content to be rendered can be provided for a rendering resource pool independent of the cloud server for rendering.
In this embodiment, the cloud server is not responsible for performing a specific screen rendering operation, but performs the screen rendering operation by using the rendering resources in the rendering resource pool. The requirement on the cloud server is reduced, the cloud server does not need rendering resources, and the realization cost of the cloud server is reduced.
In embodiments of the present application, an implementation manner in which the cloud server provides the to-be-rendered screen content to the rendering resource pool is not limited. For example, the cloud server may provide a storage space for the rendering resource pool, store the to-be-rendered screen content in the storage space, and notify the rendering resource pool to read the to-be-rendered screen content in the storage space. For another example, the cloud server may also transmit the screen content to be rendered to the rendering resource pool based on a network channel between the cloud server and the rendering resource pool. The cloud server and the rendering resource pool can be connected through a network.
