In one implementation, the master sub-device 110 is further configured to determine whether to allow multiple heterogeneous sub-devices 120 to simultaneously download key components required for their booting; and if so, executing the reply of the second download reply aiming at the second download request.

In one case, the data volume of the basic component required for the heterogeneous sub-device to boot is small, while the data volume of the key component required for the heterogeneous sub-device to boot is large. In this implementation manner, in order to better improve the starting speed of the heterogeneous device, and avoid the situation that the time consumed for starting the downloading of the heterogeneous sub-devices is long due to the bandwidth limitation of the main control sub-device 110 when too many heterogeneous sub-devices 120 download the key components required for starting the heterogeneous sub-devices from the main control sub-device 110 in parallel, before replying the second download reply to the second download request, the main control sub-device 110 may determine whether to allow the plurality of heterogeneous sub-devices 120 to download the key components required for starting the heterogeneous sub-devices at the same time, if the determination result is yes, that is, if it is determined that the plurality of heterogeneous sub-devices 120 are allowed to download the key components required for starting the heterogeneous sub-devices at the same time, reply to each received second download request, so that each heterogeneous sub-device can download the key components required for starting the heterogeneous sub-devices from the main control sub-device.

The second download request carries the IP address of the corresponding heterogeneous sub-device 120, and the main control sub-device 110 may reply the second download reply to the heterogeneous sub-device 120 based on the IP address of each heterogeneous sub-device 120.

In one implementation, the master sub-device 110 is a different heterogeneous sub-device, and there may be differences in the basic components required for the heterogeneous sub-device 120 to boot. After the heterogeneous sub-device 120 finishes downloading the basic components, when sending the second download request, the second download request may carry verification information of the key component corresponding to the basic component that has been downloaded, and then the main control sub-device 110 may reply a second download reply to the heterogeneous sub-device 120 according to the verification information of the key component that is carried in each second download request, where the second download reply carries a download address of the key component corresponding to the verification information of the key component, so as to ensure that the heterogeneous sub-device 120 can download the correct key component based on the download address carried in the second download reply, and ensure normal start of the heterogeneous sub-device 120.

In another implementation, if the determination result is negative, it is determined that the plurality of heterogeneous sub-devices 120 are not allowed to simultaneously download the key component required for starting the heterogeneous sub-devices, and a preset number of heterogeneous sub-devices 120 are determined from the plurality of heterogeneous sub-devices 120 as the first heterogeneous sub-device 121; replying a second download reply to the second download request sent by each first heterogeneous child device 121;

the first heterogeneous sub-device 121 is configured to receive the second download reply, and download the key component from the download address carried in the received second download reply; after downloading the key component, in a case that a second download request sent by the second heterogeneous sub-device 122 is received, replying a third download reply based on the received second download request, where the third download reply carries an address of the first heterogeneous sub-device 121 storing the downloaded key component, and the second heterogeneous sub-device 122 includes: heterogeneous sub-equipment which does not download key components required by the start of the heterogeneous equipment in the heterogeneous equipment starting system;

and the second heterogeneous sub-device 122, configured to, after receiving the third download reply, download the key component from the address carried in the received third download reply to complete the startup.

The preset configuration number may be set according to the performance of the master sub-device 110. In one case, the master sub-device 110 may detect its own performance periodically or aperiodically, and then automatically adjust the preset configuration number. Alternatively, the preset configuration number may be manually adjusted by a worker.

In this implementation manner, if the determination result is negative, that is, if it is determined that the bandwidth of the heterogeneous sub-device 120 does not allow the plurality of heterogeneous sub-devices 120 to simultaneously download the key component required for starting the heterogeneous sub-devices, a preset number of heterogeneous sub-devices are determined from the plurality of heterogeneous sub-devices 120 to serve as the first heterogeneous sub-device 121, and then the first heterogeneous sub-device 121 is allowed to download the key component from the heterogeneous sub-device, that is, the key component is downloaded from the download address carried by the second download reply. Fig. 2E is a schematic view of a scenario in which the main control sub-device 110 replies to the second download reply; as shown in fig. 2F, a scene diagram of downloading key components by the first heterogeneous sub-device 121 is shown.

Subsequently, the second heterogeneous sub-device, which is another heterogeneous sub-device that does not download the key component, may always send the second download request, as shown in fig. 2G, which is a scene diagram illustrating that the second heterogeneous sub-device 122 sends the second download request. After the first heterogeneous sub-device 121 finishes downloading the key components, in the case of receiving the second download request sent by the second heterogeneous sub-device 122, replying a third download reply based on the received second download request. The first heterogeneous sub-device 121 that has already downloaded the key component actively shares the burden of component downloading of the main control sub-device 110, so as to reduce the bandwidth resource occupation of the main control sub-device 110 during the starting process of the heterogeneous devices, and to a certain extent, the time for starting the downloading of the heterogeneous sub-devices can be shortened. Fig. 2H is a schematic diagram of a scenario in which the first heterogeneous sub-device 121 sends the third download reply. Fig. 2M is a schematic view of a scenario in which a second heterogeneous sub-device downloads a key component from a first heterogeneous sub-device.

In one case, each heterogeneous sub-device may download a basic component with a smaller data size required for starting from the master sub-device, and when a request is made to the master sub-device to download a key component with a larger data size required for starting, the master sub-device determines, through its own bandwidth, whether all the heterogeneous sub-devices can be supported for parallel downloading, and when it is determined that all the heterogeneous sub-devices can be supported for parallel downloading of the key component; when the support is determined not to be available, allowing the screened first heterogeneous sub-devices to download the key component from the main control sub-device, and then actively sharing the load of component downloading of the main control sub-device 110 by the first heterogeneous sub-device 121 which has downloaded the key component, so as to reduce the bandwidth resource occupation of the main control sub-device 110 in the starting process of the heterogeneous devices and realize more intelligent starting of the heterogeneous devices.

In an implementation manner, the main control sub-device 110 is further configured to, after determining that the first heterogeneous sub-device 121 finishes downloading the key component required for starting the heterogeneous sub-device, and in a case that a second download request sent by the second heterogeneous sub-device 122 is received, if it is determined that the plurality of second heterogeneous sub-devices are not allowed to simultaneously download the key component required for starting the heterogeneous sub-device, determine, from the plurality of second heterogeneous sub-devices 122, a preset configuration number of heterogeneous sub-devices as new first heterogeneous sub-devices, and reply a second download reply to each new second download request sent by the first heterogeneous sub-device;

and the new first heterogeneous sub-device is used for receiving the second download reply and downloading the key component from the download address carried by the received second download reply to finish the starting.

In order to better improve the starting speed of the heterogeneous devices, after determining that the first heterogeneous sub-device finishes downloading the required key components, in the case of receiving a second download request sent by the second heterogeneous sub-device 122, the main control sub-device 110 may further continue to provide the second heterogeneous sub-device 122 with the download addresses of the key components required for starting, so that the second heterogeneous sub-device may continue to download the key components required for starting from the main control sub-device 110 after receiving the download addresses of the key components required for starting provided by the main control sub-device 110.

In one implementation, the master sub-device 110 may determine whether to allow all the heterogeneous sub-devices 120 in the heterogeneous devices to simultaneously download key components required for its startup from the master sub-device 110 by determining a size between the number of the heterogeneous sub-devices 120 in the heterogeneous devices and a preset configuration number. Wherein the master sub-device 110 is specifically configured to

Determining whether the number of the plurality of heterogeneous sub-devices 120 is not higher than a preset configuration number, wherein if the number of the plurality of heterogeneous sub-devices 120 is not higher than the preset configuration number, determining that the plurality of heterogeneous sub-devices 120 are allowed to simultaneously download key components required for starting; if the number of the heterogeneous sub-devices 120 is determined to be higher than the preset configuration number, it is determined that the plurality of heterogeneous sub-devices 120 are not allowed to simultaneously download the key components required for starting.

In one case, the master sub-device 110 is a different first heterogeneous sub-device, and there may be differences in the basic components required for booting provided. The second download request sent by the first heterogeneous child device may carry check information of a key component required by the first heterogeneous child device, and after receiving the second download request, the main control child device 110 replies a second download reply carrying a download address of the key component corresponding to the basic component that has been downloaded by the first heterogeneous child device to each first heterogeneous child device 121 based on the check information of the key component. The first heterogeneous sub-device 121 downloads the key component from the download address carried by the received second download reply. And (4) subsequently. The first heterogeneous sub-device 121 can only provide the key component to the second heterogeneous sub-device 122 that needs to download the key component downloaded by itself. In one implementation manner, the second download request carries verification information of a key component corresponding to a basic component downloaded by the corresponding heterogeneous sub-device, and the verification information is used as first verification information;

first heterogeneous sub-device 122, in particular for

judging whether the first check information and the second check information carried by each received second download request are the same or not;

and if the judgment result is the same, replying a third download reply aiming at the second download request.

If the first check information carried by the second download request is judged to be the same as the second check information of the key component downloaded by the heterogeneous sub-device, it can be determined that the key component required for starting the heterogeneous sub-device sending the second download request is the same as the key component downloaded by the heterogeneous sub-device, and at this time, the first heterogeneous sub-device can reply a third download reply to the heterogeneous sub-device sending the second download request. And after the heterogeneous sub-device sending the second download request receives the third download reply, downloading the key component from the first heterogeneous sub-device, and completing the starting.

The main control sub-device 110 determines a preset configuration number of heterogeneous sub-devices from the heterogeneous sub-devices, as the first heterogeneous sub-device, and the determination manner may be multiple. When the master sub-device 110 provides the same basic component and/or key component for different heterogeneous sub-devices, a preset number of heterogeneous sub-devices may be randomly determined from the heterogeneous sub-devices as the first heterogeneous sub-device. When the main control sub-device 110 provides different basic components and/or key components for different heterogeneous sub-devices, a preset number of heterogeneous sub-devices may be determined from the heterogeneous sub-devices as a first heterogeneous sub-device, where the first heterogeneous sub-device includes: and each group of basic components and at least one heterogeneous sub-device corresponding to the key component. It can be understood that there is correspondence between the base component and the key component. At least one heterogeneous sub-device corresponding to each group of basic components and key components is as follows: at least one heterogeneous sub-device of the set of base components and key components is downloaded.

When the heterogeneous sub-devices in the heterogeneous devices are all disposed in the same switch board block, the main control sub-device 110 may randomly determine a preset number of heterogeneous sub-devices from the heterogeneous sub-devices, as the first heterogeneous sub-device. In a case that heterogeneous sub-devices of the heterogeneous devices are disposed in different switch board blocks, the main control sub-device 110 may determine, based on a principle of network proximity, at least one heterogeneous sub-device from the heterogeneous sub-devices disposed in each switch board block, so as to obtain a preset configuration number of heterogeneous sub-devices, which is used as the first heterogeneous sub-device. Subsequently, the first heterogeneous sub-device may provide the key component for a heterogeneous sub-device that is not downloaded to obtain the key component and is located in the same switchboard board block. The information of the exchange board block where each heterogeneous sub-device is located may be stored in a pre-configured file.

In one implementation, the master sub-device 110 is specifically configured to

determining a preset configuration number of heterogeneous sub-devices from the plurality of heterogeneous sub-devices as a first heterogeneous sub-device based on the determined exchange board block to which each heterogeneous sub-device belongs, wherein the first heterogeneous sub-device comprises: and at least one heterogeneous sub-device corresponding to each exchange board block.

The determination process of the new first heterogeneous sub device may refer to the determination process of the first heterogeneous sub device from the plurality of heterogeneous sub devices, and is not described herein again.

In one implementation, in order to facilitate the management of the heterogeneous sub-devices 120 in the heterogeneous device by the master sub-device 110, after each of the heterogeneous sub-devices is started, the master sub-device 110 needs to be notified so that the master sub-device 110 knows the states of the heterogeneous sub-devices to prepare for subsequent work scheduling. The heterogeneous sub-devices are also used for sending a component downloading completion notice after the key component is downloaded;

the main control sub-device 110 is further configured to determine that the heterogeneous sub-device 120 is started completely after receiving the component download completion notification sent by the heterogeneous sub-device.

In one case, the heterogeneous child device may send the component download complete notification by way of broadcast.

The master control sub-device may determine that the whole heterogeneous device is started after receiving the component download completion notification sent by all the heterogeneous sub-devices in the heterogeneous devices.

In one implementation, when the heterogeneous sub-device receives a plurality of second download replies or third download replies, one of the second download replies or the third download replies may be selected as a target download reply, and key components required for self-starting are downloaded from an address carried by the target download reply. When a download reply is selected from the group as a target download reply, the following steps may be performed: selecting the earliest received download reply as the target download reply; it is also possible to select a download reply that is in the same board block as itself, as a target download reply, and so on. In another implementation, the following may be: after the heterogeneous sub-device receives one download reply, which may be the second download reply or the third download reply, the other download reply may not be received.

Corresponding to the above system embodiment, an embodiment of the present invention provides a heterogeneous device starting method, which is applied to a master control sub device in a heterogeneous device starting system, where the heterogeneous device starting system further includes a plurality of heterogeneous sub devices, and as shown in fig. 3, the method may include the following steps:

s301: if a first downloading request sent by the heterogeneous sub-equipment is received, replying a first downloading reply aiming at the first downloading request so that the heterogeneous sub-equipment downloads the basic component from a downloading address carried by the received first downloading reply; the first download request is used for requesting to download a basic component required by starting heterogeneous sub-equipment, and the first download reply carries a download address of the basic component required by starting the heterogeneous sub-equipment;

s302: receiving a second download request, and replying a second download reply aiming at the second download request so as to enable the heterogeneous sub-device to download the key component from the download address carried by the received second download reply to complete the starting, wherein the second download request is as follows: and after the heterogeneous sub-equipment finishes downloading the basic component, sending a request for requesting to download the key component required by starting the heterogeneous sub-equipment, wherein the second download reply carries a download address of the key component required by starting the heterogeneous sub-equipment.

The first download request and the second download request may be sent in a broadcast or multicast manner.

The main control sub-device is used for managing all the heterogeneous sub-devices in the heterogeneous device. After being started, each heterogeneous sub-device can be used as a functional device to provide functions supported by the heterogeneous sub-device. The master control sub-device may be a device group system or an entity device, and the master control sub-device may provide basic components and key components required for starting all the heterogeneous sub-devices in the heterogeneous device, and regulate and control downloading of the basic components and the key components required for starting all the heterogeneous sub-devices in the heterogeneous device.

In one case, when the master sub-device 110 may be a device group system, different devices in the device group system may store a basic component and a key component, and during the starting process, the device storing the basic component may reply a first download reply to the heterogeneous sub-device, and the device storing the key component replies a second download reply to the heterogeneous sub-device.

The basic components are: the components for deploying the runtime environment required for the heterogeneous child device boot may include: the heterogeneous child devices start the required embedded kernel/file system, as well as components such as specific executable files and scripts, for example: the base components may include, but are not limited to: executable files and scripts corresponding to data transmission protocols such as an HTTP (hyper text transport Protocol) File and an FTP (File Transfer Protocol) are run to support data transmission between heterogeneous sub-devices in the heterogeneous device starting system, between the heterogeneous sub-devices and a main control sub-device, and between the heterogeneous device starting system and other devices outside the system based on the corresponding data transmission protocols.

The key components include: and other necessary components which are required by the starting of the heterogeneous sub-equipment and are realized by the application layer function are used for running in the deployed running environment, and the starting and running of the heterogeneous sub-equipment are realized so as to provide the corresponding application layer function. Key components may include, but are not limited to: and providing a component for managing functional services such as operation and maintenance services and data storage services.

And moreover, resources required by starting the heterogeneous sub-equipment are grouped into basic components and key components, so that the architecture of the heterogeneous equipment starting system is more flexible.

In one implementation, before the step of replying with a second download reply to the second download request, the method may further comprise:

determining whether to allow a plurality of heterogeneous sub-devices to simultaneously download key components required for startup;

and if so, executing the step of replying the second download reply aiming at the second download request.

In one case, the amount of data of the base component required for the heterogeneous child device to boot is small, while the amount of data of the key component required for the heterogeneous child device to boot is large. In the implementation manner, in order to better improve the starting speed of the heterogeneous device, when too many heterogeneous sub-devices download key components required for starting from the main control sub-device in parallel, due to the bandwidth limitation of the main control sub-device, the situation that the time consumed for downloading and starting the heterogeneous sub-devices is long is avoided. The main control sub-device may determine whether to allow the plurality of heterogeneous sub-devices to simultaneously download the key components required for the start of the heterogeneous sub-devices before replying the second download reply to the second download request, and if the determination result is yes, that is, if it is determined that the plurality of heterogeneous sub-devices are allowed to simultaneously download the key components required for the start of the heterogeneous sub-devices, reply to the second download reply to each received second download request, so that each heterogeneous sub-device may download the key components required for the start from the main control sub-device.

The second download request carries the IP addresses of the corresponding heterogeneous sub-devices, and the master sub-device may reply a second download reply to the heterogeneous sub-devices based on the IP address of each heterogeneous sub-device.

In one case, the master sub-device is a different heterogeneous sub-device, and there may be differences in the basic components required for the provided heterogeneous sub-devices to boot. After the heterogeneous sub-devices finish downloading the basic components, when a second downloading request is sent, the second downloading request can carry verification information of key components corresponding to the basic components which are downloaded, and then the main control sub-device can reply a second downloading reply to the heterogeneous sub-devices according to the verification information of the key components carried by each second downloading request, wherein the second downloading reply carries the downloading addresses of the key components corresponding to the verification information of the key components, so that the heterogeneous sub-devices can download correct key components based on the downloading addresses carried by the second downloading reply, and normal starting of the heterogeneous sub-devices is guaranteed.

In another implementation manner, if the determination result is negative, it is determined that the plurality of heterogeneous sub-devices are not allowed to simultaneously download the key component required by the start of the plurality of heterogeneous sub-devices, and a preset number of heterogeneous sub-devices are determined from the plurality of heterogeneous sub-devices as first heterogeneous sub-devices;

replying a second download reply aiming at a second download request sent by the first heterogeneous sub-device so as to enable the first heterogeneous sub-device to download the key component from the download address carried by the received second download reply; and after the first heterogeneous sub-device finishes downloading the key component, under the condition of receiving a second download request sent by a second heterogeneous sub-device, replying a third download reply based on the received second download request, so that the second heterogeneous sub-device downloads the key component from an address carried by the received third download reply after receiving the third download reply to finish starting, wherein the third download reply carries the address of the first heterogeneous sub-device for storing the downloaded key component, and the second heterogeneous sub-device comprises: the heterogeneous device starts a heterogeneous sub-device of a system without downloading key components required by starting the heterogeneous device.

In the implementation mode, the main control sub-device determines whether all heterogeneous sub-devices can be supported for parallel downloading or not through the bandwidth of the main control sub-device, and when the main control sub-device can be supported for parallel downloading, all heterogeneous sub-devices are allowed to download key components; when the first heterogeneous sub-device is determined to be not supportable, the screened first heterogeneous sub-device is allowed to download the key component from the main control sub-device, and then the first heterogeneous sub-device which has downloaded the key component actively shares the downloading burden of the component of the main control sub-device, so that the bandwidth resource occupation of the main control sub-device in the starting process of the heterogeneous device is reduced, the starting speed of the heterogeneous device is improved better, the situation that too many heterogeneous sub-devices download the key component required for starting from the main control sub-device in parallel is avoided, and the situation that the time consumed for downloading and starting the heterogeneous sub-devices is long due to the bandwidth limitation of the main control sub-device is avoided. Therefore, the occupation of bandwidth resources of the main control sub-device 110 in the starting process of the heterogeneous device is reduced, and the time for downloading and starting the heterogeneous sub-device can be shortened to a certain extent. More intelligent startup of heterogeneous devices is achieved.

In order to better improve the starting speed of the heterogeneous device, after determining that the first heterogeneous sub-device finishes downloading the required key component, the main control sub-device may further continue to provide the second heterogeneous sub-device with the download address of the key component required for starting under the condition that a second download request sent by the second heterogeneous sub-device is received, so that the second heterogeneous sub-device may continue to download the key component required for starting from the main control sub-device when receiving the download address of the key component required for starting provided by the main control sub-device. In one implementation, the method may further include:

after determining that the first heterogeneous sub-device finishes downloading key components required by starting, under the condition that a second downloading request sent by a second heterogeneous sub-device is received, if determining that a plurality of second heterogeneous sub-devices are not allowed to simultaneously download the key components required by starting, determining a preset configuration number of heterogeneous sub-devices from the plurality of second heterogeneous sub-devices as new first heterogeneous sub-devices, and replying a second downloading reply aiming at each new second downloading request sent by the first heterogeneous sub-device; so that the new first heterogeneous sub-device downloads the key component from the download address carried by the received second download reply to complete the startup.

In one implementation, the master sub-device may determine whether to allow all the heterogeneous sub-devices in the heterogeneous devices to simultaneously download key components required for starting the heterogeneous devices from the master sub-device by determining a size between the number of the heterogeneous sub-devices in the heterogeneous devices and a preset configuration number. The step of determining whether to allow multiple heterogeneous sub-devices to simultaneously download key components required for startup may include:

judging whether the number of the heterogeneous sub-devices is not higher than a preset configuration number, wherein if the number of the heterogeneous sub-devices is not higher than the preset configuration number, determining that the plurality of heterogeneous sub-devices are allowed to simultaneously download key components required by starting; and if the number of the heterogeneous sub-devices is higher than the preset configuration number, determining that the plurality of heterogeneous sub-devices are not allowed to simultaneously download the key components required by starting.

The main control sub-device determines a preset configuration number of heterogeneous sub-devices from the heterogeneous sub-devices, and the determination mode can be multiple as the first heterogeneous sub-device. The main control sub-device determines a preset configuration number of heterogeneous sub-devices from the heterogeneous sub-devices as a first heterogeneous sub-device, and the determination mode can be various. When the master sub-device provides the same basic component and/or key component for different heterogeneous sub-devices, a preset number of heterogeneous sub-devices may be randomly determined from the heterogeneous sub-devices as the first heterogeneous sub-device. When the master control sub-device provides different basic components and/or key components for different heterogeneous sub-devices, a preset configuration number of heterogeneous sub-devices may be determined from the heterogeneous sub-devices as a first heterogeneous sub-device, where the first heterogeneous sub-device includes: and each group of basic components and at least one heterogeneous sub-device corresponding to the key component. It can be appreciated that there is a correspondence between the base component and the key component. Each group of basic components and at least one heterogeneous sub-device corresponding to the key component are as follows: at least one heterogeneous sub-device of the set of base components and key components is downloaded.

When the heterogeneous sub-devices in the heterogeneous devices are all arranged in the same switchboard board, the main control sub-device can randomly determine a preset configuration number of heterogeneous sub-devices from the heterogeneous sub-devices to serve as the first heterogeneous sub-devices. Under the condition that heterogeneous sub-devices in the heterogeneous devices can be arranged in different switch board blocks, the main control sub-device can determine at least one heterogeneous sub-device from the heterogeneous sub-devices arranged in each switch board block based on a principle of network proximity so as to obtain a preset configuration number of heterogeneous sub-devices as the first heterogeneous sub-device. Subsequently, the first heterogeneous sub-device may provide the key component for a heterogeneous sub-device that is not downloaded to obtain the key component and is located in the same switchboard board block. The information of the exchange board block where each heterogeneous sub-device is located may be stored in a pre-configured file.

In an implementation manner, the determining, from the multiple heterogeneous subsets, a preset configuration number of heterogeneous subsets may include:

determining a preset configuration number of heterogeneous sub-devices from the plurality of heterogeneous sub-devices as a first heterogeneous sub-device based on the determined exchange board block to which each heterogeneous sub-device belongs, wherein the first heterogeneous sub-device comprises: and each exchange board block corresponds to at least one heterogeneous sub-device.

In one implementation, in order to facilitate the master sub-device to manage the multiple heterogeneous sub-devices in the heterogeneous device, after each of the heterogeneous sub-devices is started, the master sub-device needs to be notified, so that the master sub-device knows the states of the heterogeneous sub-devices to prepare for subsequent work scheduling. The method may further comprise:

and after receiving a component downloading completion notification sent by the heterogeneous sub-device, determining that the heterogeneous sub-device is started completely.

The master control sub-device may determine that the whole heterogeneous device is started completely after receiving the notification of completion of component downloading sent by all the heterogeneous sub-devices in the heterogeneous devices.

Corresponding to the above system embodiment, an embodiment of the present invention provides a heterogeneous device starting method, which is applied to each heterogeneous sub device in a heterogeneous device starting system, where the heterogeneous device starting system further includes a master sub device, and as shown in fig. 4, the method may include the steps of:

s401: sending a first download request so that the main control sub-device replies a first download reply to the first download request after receiving the first download request, wherein the first download request is used for requesting to download a basic component required by starting the heterogeneous sub-device, and the first download reply carries a download address of the basic component required by starting the heterogeneous sub-device;

s402: receiving a first download reply, and downloading the basic component from a download address carried by the received first download reply;

s403: after the basic component is downloaded, sending a second downloading request, wherein the second downloading request is used for requesting to download a key component required by starting the heterogeneous sub-equipment;

s404: if a second download reply replied by the main control sub-equipment aiming at the second download request is received, downloading the key component from a download address carried by the received second download reply to finish the starting, wherein the second download reply is as follows: and after receiving the second download request, the main control sub-device replies to the second download request, wherein the second download reply carries a download address of the key component required by starting the heterogeneous sub-device.

In this implementation manner, after the first heterogeneous sub-device finishes downloading the key component, the third download reply is replied based on the received second download request when receiving the second download request sent by the other heterogeneous sub-devices. The first heterogeneous sub-device which has downloaded the key component actively shares the download burden of the component of the main control sub-device, so that the occupation of bandwidth resources of the main control sub-device in the starting process of the heterogeneous device is reduced, and the time for starting the download of the heterogeneous sub-device can be shortened to a certain extent.

In one implementation, the method may further include:

under the condition that a second download reply sent by the main control sub-device is not received, if a third download reply is received, downloading the key component from the address of the key component downloaded by the first heterogeneous sub-device carried by the received third download reply, so as to complete the starting, wherein the third download reply is as follows: after the first heterogeneous sub-device finishes downloading key components required by the start of the first heterogeneous sub-device, the first heterogeneous sub-device replies to the second download request, and the first heterogeneous sub-device is as follows: the heterogeneous device starts a heterogeneous sub-device which finishes the key component and is downloaded in the system.

In one implementation, after the step of downloading the key component from the download address carried by the received second download reply, the method may further include:

under the condition that a second download request sent by a second heterogeneous sub-device is received, replying a third download reply based on the received second download request, wherein the third download reply carries an address of a key component stored and downloaded by the heterogeneous sub-device, and the second heterogeneous sub-device comprises: the heterogeneous device starts the heterogeneous sub-device of the system without downloading the key component required by the starting.

In one case, the master sub-device is a different first heterogeneous sub-device, and there may be differences in the basic components required for booting provided. The second download request sent by the first heterogeneous sub-devices may carry verification information of the key component required by the first heterogeneous sub-devices, and after receiving the second download request, the main control sub-devices reply to each first heterogeneous sub-device a second download reply carrying a download address of the key component corresponding to the basic component that has been downloaded by the first heterogeneous sub-devices, based on the verification information of the key component. And the first heterogeneous sub-equipment downloads the key component from the download address carried by the received second download reply. And (4) subsequently. The first heterogeneous sub-device can only provide the key component to a second heterogeneous sub-device that needs to download the key component downloaded by itself. In one implementation manner, the second download request carries verification information of a key component corresponding to a basic component downloaded by the corresponding heterogeneous sub-device, and the verification information is used as first verification information;

the replying to the third download reply based on the received second download request may include:

Corresponding to the foregoing system embodiment, an embodiment of the present invention provides an apparatus for starting a heterogeneous device, where the apparatus is applied to a master control sub-device in a heterogeneous device starting system, and the heterogeneous device starting system further includes a plurality of heterogeneous sub-devices, and as shown in fig. 5, the apparatus includes:
