It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art without the exercise of inventive faculty, are intended to be within the scope of the application, based on the embodiments in the specification.
The specification provides a cloud container generation method. The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a cloud container generating method according to an embodiment of the present disclosure, which may specifically include the following steps:
S100: a demand service is determined.
S102: and determining a plurality of equipment nodes corresponding to the demand service according to the demand service and the equipment service corresponding to each equipment node in the pre-constructed distributed system.
In the development scenario of internet applications, service developers can use cloud services provided by other cloud service providers to develop applications.
The cloud container generation method provided by the specification can be used for generating a cloud container provided by a cloud service providing direction service developer, the cloud container provides an integral device service capability for the service developer by packaging device services of all bottom devices, and the service developer can conduct application development based on a service interface provided by the cloud container.
In particular, the cloud service provider may determine a demand service proposed by the service developer, which may be a comprehensive service integrating a plurality of device services. And then, determining a plurality of equipment nodes corresponding to the demand service based on the demand service and the equipment service corresponding to each equipment node in the pre-constructed distributed system.
The pre-constructed distributed system comprises a plurality of equipment nodes, the equipment services provided by different equipment nodes are different, and when the equipment nodes can provide a plurality of services, the equipment services corresponding to the equipment nodes can be defined from the plurality of services which can be provided according to the requirements. For example, the mobile phone can provide services such as navigation and communication, the communication service can be defined as equipment service corresponding to the mobile phone, the television can provide services such as video watching and large-screen display, and the large-screen display can be defined as equipment service corresponding to the television.
For example, if the desired service is to simulate a gamepad with a cell phone, the game is played on a local large screen television display. The mobile phone node in the distributed system can provide the service of the simulation handle, the television node provides the large-screen display capability, and the cloud server node provides the service of the operation resource. The demand service then corresponds to the cell phone node, the television node, and the cloud server node in the distributed system.
Further, in other embodiments of the present disclosure, the execution body of the cloud container generating method may be a user or a service developer, and the cloud container may be generated by linking each device node through a client provided by the cloud service provider.
S104: and generating a cloud container corresponding to the demand service according to the plurality of equipment nodes corresponding to the demand service.
In one or more embodiments of the present disclosure, to improve flexibility of service customization, a cloud container integrating service of each device is further defined on the basis of service of devices provided by each device node in a distributed system, where the cloud container provides comprehensive service of devices as a whole by encapsulating service of devices of several devices.
Specifically, a cloud container corresponding to the demand service may be created first. And then, acquiring service information of equipment service of the equipment node aiming at each equipment node corresponding to the demand service, and establishing service links between the cloud container and the equipment node based on an application layer protocol according to the acquired service information of the equipment service of the equipment node. The service link is used for enabling the cloud container to acquire equipment services provided by the equipment node. And finally, receiving the equipment service sent by the equipment node through the established service link, and updating the service configuration information of the cloud container according to the received equipment service of the equipment node. The service configuration information comprises device services provided by devices which establish service links with the cloud container.
As shown in fig. 2, the device a and the device B in fig. 2 are two device nodes in the distributed system, and assuming that the required service is composed of the service capability a and the service capability B, a container C corresponding to the required service may be created, a service link between the device a and the container C is established through the application layer protocol a, and a service link between the device B and the container C is established through the application layer protocol B. The container C can thus provide both the service capability a and the service capability B.
The demand service is continuously taken as an example of simulating a game handle by a mobile phone, and playing games are displayed on a local large-screen television. And creating a game screen display container according to the mobile phone node, the television node and the cloud server node corresponding to the demand service, wherein the game screen display container integrates the equipment service of each equipment node. Then, by running the service instance in the game screen display container, the game page is rendered to the television screen and manipulated using the mobile phone simulated handle device.
Further, if each device node in the pre-built distributed system cannot provide at least part of the required service, that is, the required service exceeds the service range that can be provided by the distributed system, before determining a plurality of device nodes corresponding to the required service, the at least part of the required service may be used as a target service, and a target device capable of providing the target service may be added to the distributed system according to the target service.
And when determining a plurality of device nodes corresponding to the demand service, determining the target device as at least one of the device nodes corresponding to the demand service.
Furthermore, for each equipment node corresponding to the demand service, when the equipment deployed by the cloud container and the equipment node are under the same local area network, the equipment node can be directly connected through the local area network. As shown in fig. 3, when the device a and the device B are in the same lan, the device management module of the device a may acquire the service capability a of the device a, and broadcast the service capability a of the device a on a specific channel based on the communication protocol and the native system capability of the device a. The communication protocol module of the equipment B can adopt the capability of a primary system, monitor the service information broadcast by the equipment A, report the service information broadcast by the equipment A to the equipment management module of the equipment B, and establish the service link between the equipment A and the equipment B through a local area network based on an application layer protocol by the equipment management module of the equipment B.
When device a establishes a service link with device B, device B may first send a link establishment request to device a based on the communication protocol and native system capabilities. The equipment A can carry out identity verification according to verification information carried in the link establishment request, establishes a communication link with the equipment B after the identity verification is passed, and returns parameter information required by subsequent establishment of service links to the equipment B. Thereafter, the device B may establish a service link with the device a based on the application layer protocol and the received parameter information, and update service configuration information in the device a and a device management module in the device B, where the service configuration information includes service capabilities of the device itself and service capabilities of other devices that establish service links with the device. Wherein the solid line represents the procedure of establishing a communication link between the device a and the device B, and the broken line represents the procedure of establishing a service link between the device a and the device B.
When the device deployed by the cloud container is under a different local area network than the device node, service links can also be established through other device nodes in the distributed system. As shown in fig. 4, the device a and the device C are located under different local area networks, and the device C may obtain service information of a device service provided by the device a from a device management server in the distributed system, where the service information includes at least a device address of the device a. The device C may then send a link establishment request to the device a based on the communication protocol and the native system capabilities according to the acquired service information. The device A can perform identity verification according to verification information carried in the link establishment request, establish a communication link with the device C after the identity verification is passed, and return parameter information required by subsequent establishment of service links to the device C. Thereafter, the device C may establish a service link with the device a based on the application layer protocol and the received parameter information, and update service configuration information in the device a and a device management module in the device C, where the service configuration information includes service capabilities of the device itself and service capabilities of other devices that establish service links with the device. After joining the distributed system, the device a registers the service information of its own device service in the device management server in the distributed system.
When the two parties of the equipment are under the same local area network, the communication protocol can establish a communication link through a narrow-band physical channel, the application layer protocol can establish a service link through a high-speed broadband channel, and the communication protocol and the application layer protocol can be packaged into an internet protocol to establish a link through the local area network. When the two sides of the device are in different local area networks, the communication protocol and the application layer protocol can be encapsulated into an internet protocol to establish a link through a wide area network.
In other embodiments of the present description, when a device is specified in an application layer protocol to provide sensor data services, the application layer protocol may also carry to establish a link in a communication protocol, or the communication protocol may also carry to establish a link in an application layer protocol.
Based on the cloud container generating method shown in fig. 1, a plurality of device nodes corresponding to the demand service can be determined according to the customized demand service and the device service corresponding to each device node in the pre-constructed distributed system. And then, generating a cloud container corresponding to the demand service according to a plurality of equipment nodes corresponding to the demand service. By abstracting the service capability taking the device service as a unit from the application layer, the difference of fragmentation of the bottom layer is shielded, and flexible configuration of various device services is realized.
In this specification, functional modules of each device may be divided into native system capabilities, interface protocols, device management, and service capabilities in order from the bottom layer. As shown in fig. 5, the native system capability relates to a wireless connection manner of a physical layer, such as wireless communication WIFI, 4G, 5G, and the like, a wired connection manner, such as universal serial bus (Universal Serial Bus, USB), control bus (Controller Area Network, CAN), and the like, and an operating system, such as Android, apple system IOS, and real-time operating system (Real Time Operating System, RTOS), and the like. The interface protocol may be divided into a communication protocol for discovery and configuration of devices and an application layer protocol for establishing service links between devices. And the device management module of the device application layer is used for controlling a series of functions of publishing, registering, sharing, identity verification, accessing, scheduling and the like of the device.
In one embodiment of the present disclosure, after the service link between the cloud container and the device node is established, an interface for adjusting the device service of the device node may be further encapsulated according to the established service link and the service information of the device service of the device node, and stored in the cloud container. When a service developer writes a program, the service developer can directly call the equipment service corresponding to the service interface stored in the cloud container by calling the service interface.
In one embodiment of the present disclosure, the generated cloud container may also be re-used as a virtual device node in the distributed system. And then, according to the equipment service of each equipment node corresponding to the demand service, determining the equipment service of the cloud container, taking the cloud container as a virtual equipment node, taking the equipment service of the cloud container as the equipment service of the virtual equipment node, and adding the cloud container into the distributed system. For example, assuming that Yun Rongqi M establishes service links with the device N and the device L, respectively, the cloud container M may provide the device service N and the device service L, and may use the cloud container M as a virtual device node in the distributed system, and when the demand service includes the integrated service of the device service N and the device service L, the cloud container M may provide a unified interface of encapsulation.
In one embodiment of the present disclosure, an application layer protocol between devices may be defined by the services provided by the devices, which is not limited in this disclosure. If the mobile phone simulates the game handle, the service protocol of the mobile phone can be set according to the corresponding relation between the operation of the mobile phone interface and the game control,
In one embodiment of the present disclosure, if the device D establishes a service link with the device E, that is, the device D may link the service capability E of the device E, and the device E may also link the service capability D of the device D, the service capability E may be regarded as a service capability of the device D. Device F may then also link the service capabilities E of device D when device D again establishes a service link with device F. For example, assuming that the device D is a mobile phone, the device E is a temperature controller, and the device F is a television, after the mobile phone establishes a service link with the temperature controller, the temperature control can be performed through the mobile phone. After the television establishes a service link with the mobile phone, temperature control can also be performed through the television.
Further, in this specification, when the required service is turned off, a communication link may be established between the devices through a communication protocol, and any one of the devices initiates a device release request, deletes the application layer protocol configuration of both the devices, updates the service configuration information of both the devices, and further disconnects the service link established between the device nodes.
In one or more embodiments of the present disclosure, after generating a cloud container corresponding to a required service, the service provider may write a computer program based on a service interface provided by the cloud container on the basis of the cloud container. So that when a computer program is run in a cloud container, for each device service that the computer program requests to call, a device node that provides the device service is determined from a number of device nodes, and resources of the device node are provided to the computer program.
In addition, in one embodiment of the present disclosure, a user may determine each device to be integrated with a service according to his own needs, and add each device to a distributed system through a client provided by a cloud service provider, and then generate a cloud container for aggregating services of each device based on each device node in the distributed system in the client. Then, the user can download a computer program pre-written by the service developer and run the computer program in the cloud container, thereby realizing the comprehensive service required by the user.
For example, if a user wants to put a game screen on a large screen of a television when playing a game, but the interface between the television and the game console is damaged, and the game handle fails, the user can simulate the game handle by using a mobile phone, and wirelessly connect the game console with the television, run a game program by using the game console, and display the game interface by using the large screen of the television, that is, combine the functions of the mobile phone, the game console and the television to provide overall equipment service.
Therefore, the user can respectively use the mobile phone, the television and the game host as equipment nodes to be added into a preset distributed system through the client provided by the cloud service provider. The device service provided by the mobile phone node is a handle-simulating service, the device service provided by the television node is a large-screen display service, and the device service provided by the game host is a service for providing computing resources for running a game program.
Then, the user can create a game screen display container in the client, and establish service links of the game screen display container with the mobile phone, the television and the game host respectively based on an application layer protocol, so that the game screen display container can integrate comprehensive services of all devices for establishing service links. As shown in fig. 6, the gray-filled game screen display container in fig. 6 can establish a service link with a mobile phone based on the application layer protocol 1, establish a service link with a television based on the application layer protocol 2, and establish a service link with a game host based on the application layer protocol 3. The application layer protocol corresponding to each device may be set based on the device service provided by each device, which is not limited in this specification.
The user may then download a computer program pre-written by the service developer, including a computer program running in the cell phone and a computer program running in the cloud container.
When the integrated service of simulating a game handle by a mobile phone and throwing a game interface to a television large screen is realized, the operation information of a user on the mobile phone can be uploaded to the cloud container by running a computer program in the mobile phone. Then, the operation of the user on the mobile phone is converted into an operation instruction of the game by running the computer program in the cloud container. And then, according to the service link established between the cloud container and the game host, calling the equipment service of the game host, running a game program in the game host based on the operation instruction of the user, and sending the running display result to the cloud container. Finally, the running display result of the game can be put into a television large screen for display by running a computer program in the cloud container based on the service link established by the cloud container and the television.
In one embodiment of the present disclosure, a service developer may also customize access to devices based on its own needs, add the devices to a distributed system through a client provided by a cloud service provider, and generate a cloud container integrating services of each device, so as to perform application development based on the cloud container.
For example, assume that a service developer needs to implement a control function of the smart home, and remotely control each home device through a mobile phone. The service developer can add home equipment such as air conditioners, lamps and televisions and mobile phones into a preset distributed system through clients provided by the cloud service provider. And then, an intelligent home control container is created in the client, service links between the intelligent home control container and an air conditioner, a lamp, a television and a mobile phone are respectively established based on an application layer protocol, and equipment services such as temperature control, light control, television remote control and mobile phone display are obtained through the service links.
When application development is performed, the service developer can write a computer program based on each service interface packaged in the cloud container and the requirement of application development. The computer program comprises a computer program running in a smart home control container and a computer program running in a mobile phone.
When a user uses an application developed by a service developer, the user can upload the operation information of the user to the intelligent home control container by running a computer program in the mobile phone, so that the cloud container converts the operation information of the user into a control instruction for equipment, and the service interface of each equipment is called by running the computer program in the intelligent home control container, so that each equipment is correspondingly controlled based on the control instruction.
In other embodiments of the present disclosure, the cloud service provider may also use the generated cloud container as an integrally packaged interface to provide the integrated service.
Assume that a cloud service provider generates a cloud container R based on water meter nodes, electricity meter nodes, and light nodes in a pre-built distributed system. And cloud container Y is generated based on the television nodes and air conditioning nodes in the distributed system. The cloud container R integrates a hydroelectric meter and control of a lamp, and the cloud container Y integrates a television switch and control of air conditioner temperature.
When the cloud service is provided for the service developer subsequently, the cloud service provider can respectively take the generated cloud container R and the cloud container Y as virtual equipment nodes in the distributed system, so that the virtual equipment nodes R and the virtual equipment nodes Y can respectively serve as a whole to provide comprehensive equipment service for the service developer. The virtual equipment node R can provide equipment services for controlling the water ammeter and the lamp, and the virtual equipment node Y can provide equipment services for controlling the television switch and the air conditioner temperature.
In summary, the cloud container generation method provided by the specification is convenient for users, service developers and cloud service providers to autonomously configure the device services of all devices, and realizes flexible combination of the device services.
It should be noted that, when determining the device node corresponding to the demand service in the present specification, the device node may be a device node having a hardware entity device in a pre-built distributed system, or may be a virtual device node corresponding to the cloud container, which is not limited in this specification and may be set according to the need. Wherein the device services provided by the virtual device nodes comprise comprehensive device services of each other device linked by the cloud container.

The embodiments of the present specification also provide a computer-readable storage medium storing a computer program, where the computer program may be used to perform the cloud container generating method provided in fig. 1 above.
According to a cloud container generating method shown in fig. 1, a schematic structural diagram of the electronic device shown in fig. 8 is further provided in the embodiment of the present disclosure. At the hardware level, as in fig. 8, the electronic device includes a processor, an internal bus, a network interface, a memory, and a non-volatile storage, although it may include hardware required for other services. The processor reads the corresponding computer program from the nonvolatile memory into the memory and then runs the computer program to implement the cloud container generating method shown in fig. 1.
Of course, other implementations, such as logic devices or combinations of hardware and software, are not excluded from the present description, that is, the execution subject of the following processing flows is not limited to each logic unit, but may be hardware or logic devices.
In the 90 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable GATE ARRAY, FPGA)) is an integrated circuit whose logic functions are determined by user programming of the device. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and create an application specific integrated circuit chip. Moreover, nowadays, instead of manually generating integrated circuit chips, such programming is mostly implemented with "logic compiler (logic compiler)" software, which is similar to the software compiler used in program development and writing, and the original code before being compiled is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but HDL is not just one, but a plurality of kinds, such as ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware Description Language)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(Ruby Hardware Description Language), and VHDL (Very-High-SPEED INTEGRATED Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, application SPECIFIC INTEGRATED Circuits (ASICs), programmable logic controllers, and embedded microcontrollers, examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component. Or even means for achieving the various functions may be regarded as either software modules implementing the methods or structures within hardware components.
The system, apparatus, module or unit set forth in the above embodiments may be implemented in particular by a computer chip or entity, or by a product having a certain function. One typical implementation is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
