Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is as follows:
with the popularization of intelligent devices, cluster networking environments in various places are becoming more and more popular, for example, in the personal home environment shown in fig. 1, various intelligent electronic product networking environments are realized, and each device is connected to a router in a wired or wireless manner to realize network access. The OTA upgrade of the existing equipment can be realized, but with the cost requirement of products, the design of single equipment in cluster equipment can optimize resources, reduce storage and computing power and the like, so that when a user needs larger storage resources or more computing power during upgrade, the single equipment cannot complete the upgrade. In order to solve the problem, an embodiment of the present invention provides a scheme for assisting in upgrading by using other devices in a cluster, so as to complete upgrading of a device to be upgraded. Since there may be multiple types of devices within a cluster, some of which may have better computing or storage capabilities, upgrades may be done with these devices. By the mode, the problem that single equipment cannot be upgraded due to insufficient capacity can be solved, high extra resources are not needed to be configured for upgrading the equipment, and cost and convenience in subsequent maintenance are both considered.
The embodiment provides a cluster collaborative upgrade method, as shown in fig. 2, which is applied to a device side to be upgraded, and includes:
s201, when the upgrade is confirmed to be needed, detecting the current upgrade capability, and acquiring the upgrade capability requirement of the current available upgrade version.
S202, when the current upgrading capability does not meet the upgrading capability requirement, sending a cooperative upgrading request to cluster equipment which is in the same network environment with the equipment to be upgraded;
s203, establishing connection with at least one auxiliary upgrading device in the cluster device according to the cooperative upgrading request;
and S204, entering an upgrading mode, receiving upgrading data sent by the upgrading assisting equipment, and writing the upgrading data into a system partition.
In this embodiment, when it is determined that upgrade is required, the current upgrade capability is detected. For example, when the device to be upgraded monitors an available upgrade version, or receives an upgrade notification message sent by a server, it indicates that the device to be upgraded needs to be upgraded, and the device to be upgraded may detect its CPU load, ROM information and RAM information required to upgrade to the available upgrade version, and the like. If the upgrade capability requirement required for upgrading to the available upgrade version cannot be met, sending a collaborative upgrade request to other devices in the cluster device, for example, a priority table may be preset in the cluster device, and the collaborative upgrade request may be sent according to one or more devices with the upgrade capability earlier in the selected priority table, or the collaborative upgrade request may be directly sent to all other devices or a specified device, and the sending of the collaborative upgrade request may use a specified data format, data content, and broadcast mode. The cooperative upgrade request at least comprises a download address of the available upgrade version, required ROM information, required RAM information and equipment connection information. Where the device connection information referred to in this example is the connection information needed by the other cluster devices to respond. As shown in fig. 3, the device to be upgraded and the assisted upgrading device are in the same local area network, and after responding to the other devices in the cluster, the device to be upgraded and the assisted upgrading device establish a connection with at least one assisted upgrading device in the cluster device, enter an upgrading mode, and receive upgrading data sent by the assisted upgrading device.
According to the embodiment, the upgrading data sent by the upgrading assisting equipment is directly written in, so that version upgrading is completed, and the problem that upgrading cannot be achieved due to insufficient resources caused by the fact that the upgrading data need to be downloaded, cached, processed and the like in the middle process in the prior art is solved.
In an example, after establishing a connection with at least one upgrade assisting device of the cluster devices, the cluster cooperative upgrade method further includes:
generating a digital certificate;
and sending the digital certificate to the upgrade assisting equipment so that the upgrade assisting equipment encrypts upgrade data according to the digital certificate.
In this example, after the device to be upgraded receives the response of the upgrade assisting device, the digital certificate is generated and sent to the upgrade assisting device, and of course, the indication data may also be sent together, where the indication data is used to indicate to the upgrade assisting device that the device to be upgraded needs to assist in upgrading. The upgrading assisting equipment can store the digital certificate, upgrade data sent by the upgrading assisting equipment is encrypted by the digital certificate, and the equipment to be upgraded can decrypt the encrypted upgrade data by the digital certificate, so that the upgrade data can be verified.
In an example, as shown in fig. 4, the receiving upgrade data sent by the upgrade assisting apparatus and writing the upgrade data into a system partition includes:
s401, receiving encrypted upgrading data sent by the upgrading assisting equipment;
s402, decrypting the encrypted upgrading data by using the digital certificate to obtain upgrading data;
and S403, writing the upgrade data into a system partition.
As an exemplary manner of writing data, in the process of assisting the upgrade device to send the upgrade data of the available version to the device to be upgraded, a part of the upgrade data may be acquired at one side of the device to be upgraded according to its current upgrade capability. Since the upgrade assisting device encrypts the upgrade data by using the digital certificate, in this example, a part of the obtained encrypted upgrade data may be decrypted by using the data certificate to obtain a part of the upgrade data, and then the part of the upgrade data is written into the system partition.
As another exemplary data writing manner, an encrypted upgrade data packet sent after assisting one side of the upgrade device to split the upgrade data of the available version in advance may be received, the basis of the data splitting may be the upgrade capability of the upgrade assisting device or may be the preset split into N upgrade data sub-packets, and the device to be upgraded only needs to decrypt the received encrypted upgrade data packet and then writes the decrypted upgrade data packet into the system partition. After the writing is finished, the equipment to be upgraded can verify the data written into the system partition, so that the data writing is ensured to be abnormal, and after the upgrading is finished, the equipment to be upgraded is restarted to enter a new system to finish the system upgrading. If the exception exists, the upgrade can be carried out again or the auxiliary upgrade equipment is requested to restore the system data.
The problem of insufficient cache space of the equipment to be upgraded can be further solved through the writing-in mode, and meanwhile, the digital certificate verifies the received upgrading data by using the digital certificate generated in the equipment discovery stage, so that the data written into the system partition is reliable and complete.
In an example, the establishing a connection with at least one assisting upgrading device in the cluster device comprises:
under the condition that two or more devices in the cluster device respond to the cooperative upgrading request, selecting one device meeting preset conditions from the two or more devices as the upgrade assisting device;
and under the condition that the cluster equipment fails to respond to the cooperative upgrading request within preset time, the upgrading is abandoned.
In this example, the device information in response is received within a certain time, if there are multiple cluster devices responding, one device is selected as an upgrade assisting device according to a preset condition, and a digital certificate is sent to the device, and the data of the end is sent to the other responding devices. The process of establishing connection with the selected assistant upgrading device also comprises the steps of starting an upgrading program to enter an upgrading mode and accessing the address and the port which are sent by the assistant device and need to be connected in the upgrading mode. The upgrade program in this example refers to a program that causes a device to be upgraded to enter an upgrade mode, where the device may implement upgrading of a system partition in the upgrade mode and may only receive data on a trusted device, and the device may implement networking in a wired or wireless manner in the upgrade mode, but the started application program only includes the upgrade program and does not start other application programs.
If no device response is received within a certain time, the upgrade is abandoned, and the cooperative upgrade request can be sent after waiting between presets.
In conclusion, the method can realize the upgrading of the equipment under the condition that the resources of the equipment cannot be upgraded, and the hardware cost and the subsequent maintenance cost of the product are considered.
The second embodiment:
this embodiment provides a method for cluster cooperative upgrade, as shown in fig. 5, which is applied to an upgrade assisting device side and includes:
s501, when a cooperative upgrading request sent by equipment to be upgraded in the same network environment in cluster equipment is monitored, detecting the current assistance upgrading capability according to the cooperative upgrading request;
s502, when the current assistance upgrading capability meets the upgrading capability corresponding to the cooperative upgrading request, establishing connection with the equipment to be upgraded;
s503, entering a collaborative upgrading mode, and sending upgrading data to the equipment to be upgraded so that the equipment to be upgraded writes the upgrading data into a system partition of the equipment to be upgraded to complete upgrading.
In this example, other devices in the cluster may first determine whether the devices themselves support the function of assisting in upgrading, if so, the devices start a monitor program for local area network broadcasting, monitor a cooperative upgrade request sent by the devices to be upgraded in a specified data format, data content, and broadcasting manner, and when monitoring the cooperative upgrade request sent by the devices to be upgraded in the cluster devices, analyze available version upgrade information of the devices to be upgraded, such as required ROM, RAM space, firmware download address, and connection information (e.g., port) of the devices to be upgraded from the received cooperative upgrade request, and comprehensively determine whether the devices themselves satisfy the upgrade capability corresponding to the cooperative upgrade request according to the upgrade information of the devices to be upgraded. If so, establishing connection with the equipment to be upgraded according to the cooperative upgrade request, for example, establishing connection with the equipment to be upgraded according to the port of the equipment to be upgraded of the cooperative upgrade request. If it is determined that the upgrade cannot be assisted, no information is sent to the upgraded device.
The process of establishing connection with the device to be upgraded may include establishing connection with the device to be upgraded after receiving indication data sent by the device to be upgraded, where the indication data is used to identify whether the device to be upgraded needs to assist in upgrading.
After the connection with the equipment to be upgraded is established, the upgrading assisting equipment can enter the upgrading assisting mode, acquire upgrading data corresponding to the available version and send the upgrading data to the equipment to be upgraded. Of course, after the connection with the device to be upgraded is established, the upgrade data corresponding to the available version may be acquired, and then the assisted upgrade mode is entered to send the upgrade data to the device to be upgraded. The specific order of obtaining the upgrade data corresponding to the available version is not limited herein.
After sending upgrade data to the equipment to be upgraded, the equipment to be upgraded writes the upgrade data into a system partition of the equipment to be upgraded, and upgrading is completed.
According to the method and the device, the upgrading data which can be directly written in are directly sent to the device to be upgraded by the aid of the upgrading device, and the device to be upgraded completes upgrading by writing the upgrading data into the system partition of the device to be upgraded. Therefore, the problem that resources of the equipment to be upgraded in the prior art need to download, cache and process the upgrading data in the middle process is solved, the process is completed by the aid of the upgrading equipment with processing capacity, and the upgrading threshold of the equipment to be upgraded is lowered.
In an example, after the connection is established with the device to be upgraded, the cluster collaborative upgrade method further includes:
receiving a digital certificate sent by the equipment to be upgraded;
encrypting the upgrading data by using the digital certificate to obtain encrypted data;
and sending the encrypted data to the equipment to be upgraded so that the equipment to be upgraded decrypts the encrypted data according to the digital certificate to obtain the upgrading data.
In this example, the indication data sent from the device to be upgraded is received, if the indication data indicates that the upgrade needs to be assisted, the received digital certificate is saved, and the address and the port which need to be connected in the upgrade mode are sent to the device to be upgraded.
And then encrypting the upgrade data by using the received digital certificate to obtain encrypted data, and sending the encrypted data to the equipment to be upgraded, wherein the specific sending mode can be that the encrypted data are sequentially sent to the equipment to be upgraded, so that the equipment to be upgraded decrypts the encrypted data according to the digital certificate to obtain the upgrade data, and the upgrade data are directly written into a system partition. Certainly, the encrypted data may also be divided into N upgrade data sub-packets according to a preset division scheme, and then the N upgrade data sub-packets are sent to the device to be upgraded in a data sub-packet manner according to a certain sequence, and after receiving the data sub-packets, the device to be upgraded writes the data packets correspondingly. In this example, the upgrade data is verified using a digital certificate to ensure that the data written to the system partition is reliable and complete.
In an example, before sending upgrade data to the device to be upgraded, the cluster collaborative upgrade method further includes:
acquiring the upgrading data according to the download address of the available upgrading version in the cooperative upgrading request;
or;
backing up original version data of the equipment to be upgraded, acquiring a differential upgrade package according to a download address of an available upgrade version in the cooperative upgrade request, and combining the original version data and the differential upgrade package into the upgrade data;
or;
and detecting current version information, and extracting the upgrade data from the local area if the current version information is adapted to the version information corresponding to the cooperative upgrade request.
Before sending the upgrade data to the device to be upgraded, several ways of obtaining the upgrade data of the device to be upgraded by the cooperative upgrade device are introduced in this example.
As an exemplary manner of obtaining the upgrade data, in this example, the upgrade data may be obtained directly by using the download address of the available upgrade version in the collaborative upgrade request. That is, the download address of the available upgrade version in the cooperative upgrade request is used to obtain the complete upgrade data. Therefore, the complete available upgrade version can be obtained without other data processing, such as data synthesis, and after the complete upgrade data is obtained, the upgrade data can be encrypted through the digital certificate and then sent.
As an exemplary manner of obtaining the upgrade data, in this example, the original version data of the device to be upgraded may be backed up, and the backup method may be to read a system partition of the device to be upgraded, so as to obtain the original data of the device to be upgraded. And then, acquiring differential upgrading data by using the download address of the available upgrading version in the cooperative upgrading request, and synthesizing the differential upgrading data and the original version data by using a differential synthesis algorithm to obtain upgrading data. And then the upgrading data is encrypted by the digital certificate and then sent. The method of the embodiment can reduce the network flow usage and the bandwidth occupation of the equipment to be upgraded.
As an exemplary manner of obtaining upgrade data, if the device to be upgraded and the upgrade assisting device are the same device, version information of the upgrade assisting device may also be detected, and if the version information of the upgrade assisting device is adapted to the version information corresponding to the cooperative upgrade request, the upgrade data may be directly extracted locally from the upgrade assisting device.
The above-mentioned upgrade data acquisition process may be performed after establishing connection with the device to be upgraded, or may be performed after assisting the upgrade device to enter the cooperative upgrade mode.
In an example, after sending upgrade data to the device to be upgraded, the cluster collaborative upgrade method further includes:
reading write-in data written in a system partition of the equipment to be upgraded;
checking the written data, and repeatedly upgrading the equipment to be upgraded under the condition that the written data are determined to be abnormal;
alternatively, the first and second liquid crystal display panels may be,
and restoring the equipment to be upgraded by using the original version data.
In this example, the written data is further verified, the written data written into the system partition of the device to be upgraded is read, data verification is performed, whether the upgraded data is normal or not is confirmed, and if the verification is abnormal, the upgrading process can be performed again. Or restoring the equipment to be upgraded by using the original version data backed up in advance. If the verification is normal, the equipment to be upgraded is upgraded, and a new system version can be entered.
When the resources of the equipment to be upgraded are insufficient, the equipment to be upgraded is synthesized and stored by assisting the available resources of the equipment to be upgraded, the characteristics of the cluster environment can be fully utilized, and the equipment to be upgraded is upgraded, so that the problem that the equipment to be upgraded cannot be upgraded due to insufficient resources originally is solved. The auxiliary upgrading equipment meeting the conditions can be quickly acquired from the cluster by using the specified data format, the data content and the broadcasting mode, wherein the defined connection method of the upgraded equipment and other equipment in the cluster can more efficiently complete the connection of useful equipment, and avoid invalid connection. By using the auxiliary upgrading device, the system restoration under the condition that the equipment to be upgraded fails to be upgraded or is abnormal can be realized, and the condition that the upgraded equipment has to be returned to the factory for maintenance once the upgraded equipment is abnormal (cannot normally enter the system) in the existing upgrading process is also improved. The auxiliary upgrading device utilizes the difference upgrading packet and the original system data of the device to be upgraded to realize the synthesis of the target data, so that the bandwidth pressure of downloading the system data from the Internet environment can be effectively reduced, and the pressure of the server is reduced.
