[0045] To make the following embodiments clear, first, the technical terms to be involved in the embodiments of the present application are introduced:

[0046] SSH protocol is a network protocol used to provide security protection for network login and remote command execution in an insecure network environment. It mainly ensures the secure transmission of data through encryption technology to prevent sensitive data from being eavesdropped or tampered with during transmission.

[0047] ADB is a command line tool developed by Google, mainly used for communication and management between the developer's computer and Android device.

[0048] WebSocket protocol is a network communication protocol that allows full-duplex communication over a single TCP connection. Unlike HTTP, WebSocket allows persistent two-way data flow between server and client, making real-time communication more efficient and convenient.

[0049] WebRTC (Web Real-Time Communication) is an open-source project that aims to provide real-time communication capabilities to browsers and mobile applications without the need for plugins or third-party software. WebRTC supports real-time audio, video, and data communication and is widely used in scenarios such as video conferencing, online education, and real-time gaming.

[0050] RTP (Real-time Transport Protocol) is a network protocol used for transmitting multimedia data such as audio and video over the Internet. RTP is mainly used in real-time communication applications such as video conferencing, online live streaming, and real-time gaming, and its design goal is to provide low-latency and efficient data transmission.

[0051] RTCP (Real-time Transport Control Protocol) is a control protocol used in conjunction with RTP and is mainly used to monitor and report the quality of RTP sessions.

[0052] PaaSDashboard (Platform Administration Control Panel). It provides a user interface for developers and service administrators to manage and monitor the PaaS services they use.

[0053] As described above, in the current management scheme for operating system instances in the Internet of Vehicles cloud desktop, it usually relies on traditional SSH (Secure Shell) login and local ADB (Android DebugBridge) tools to debug and manage multiple types of operating system instances. However, as the number of operating system instances increases, this method is difficult to quickly and effectively manage a large number of operating system instances, and the existing management scheme for operating system instances has the problem of low management efficiency.

[0054] To solve the above problems, the embodiments of the present application provide a management system, method and medium for operating system instances, which are applied in the Internet of Vehicles cloud platform, and specifically include a node management module and a debugging processing module, wherein the node management module is provided with an identity authentication unit and a first connection establishment unit, and the debugging processing module is provided with a second connection establishment unit and a debugging unit.

[0055] When the user terminal needs to debug the operating system instance in the Internet of Vehicles cloud platform, the target instance debugging request of the user terminal is responded by the identity authentication unit, so as to verify according to the identity authentication signature of the user terminal. Since the identity authentication signature of the user terminal is generated based on the signature verification key of the Internet of Vehicles cloud platform, the user only needs to verify once to access all nodes and operating system instances in the Internet of Vehicles cloud platform, thereby avoiding the problem of repeated login when applying the traditional SSH login, and improving the management efficiency of the operating system instance. Further, when the identity authentication signature of the user terminal is passed, on the basis of the traditional SSH protocol, the Web socket protocol and the SSH protocol session are combined to establish a bidirectional communication connection between the user terminal and the target node, so as to ensure the low-latency interaction between the user terminal and the target node, thereby simulating a complete debugging interaction environment through seamless integration between the Websocket protocol and the SSH protocol, so that the user can obtain similar experience to the traditional SSH terminal in the browser, further improving the management efficiency of the operating system instance. Finally, on the basis of the bidirectional communication between the user terminal and the target node, the WebRTC channel between the user terminal and the target operating system instance is established through the bidirectional communication between the two, and the debugging of the user terminal to the target operating system instance is realized based on the WebRTC channel, so as to ensure that the user terminal can remotely debug the operating system instance by using the real-time communication capability of WebRTC, thereby improving the management efficiency of the operating system instance in many ways.

[0056] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0057] Referring to Figure 1 and Figure 2 , Figure 1 a structural schematic diagram of an operating system instance management system provided by an embodiment of the present application, Figure 2 a signaling interaction schematic diagram between modules in a management system provided by an embodiment of the present application. Figure 2The management system of the operating system instance in the actual application scenario is shown, the corresponding operating system instance is a Redroid instance applying an Android operating system, correspondingly, the Web shell module corresponds to the node management module in the embodiment of the application, the Web ADB module corresponds to the debugging processing module, and the Web Log module corresponds to the log management module. The user end logs in and accesses through the PaaSDashboard, so as to obtain the management permission of the operating system instance in the Internet of Vehicles cloud platform.

[0058] In the following introduction of Figure 1 , the actions performed by each module in Figure 2 and the functions achieved can be combined for understanding.

[0059] As shown in Figure 1 , the vehicle network cloud platform includes a node management module 100 and a debugging processing module 200. In the node management module 100, an identity authentication unit 1001 and a first connection establishment unit 1002 are arranged. In the debugging processing module 200, a debugging unit 2001 and a second connection establishment unit 2002 are arranged.

[0060] The identity authentication unit 1001 is configured to respond to a target instance debugging request from a user end, perform identity authentication on the user end according to an identity authentication signature of the user end, and obtain an identity authentication result. The identity authentication signature is generated based on a signature verification key of the vehicle network cloud platform.

[0061] In the vehicle network cloud platform provided in the embodiment of the application, each operating system instance is arranged in a corresponding target node. Therefore, when a user needs to debug a target operating system instance, the user needs to obtain the access permission of the target node.

[0062] As known from the foregoing, in the prior operating system debugging scheme, the traditional SSH login needs the user to repeatedly verify the access permission of the target node, and the user needs to repeatedly input the login information, thereby resulting in low management efficiency of the operating system instance.

[0063] Therefore, in order to avoid the user from repeatedly inputting the login information, the embodiment of the application adopts a password-free authentication mechanism in asymmetric encryption to perform identity authentication on the user. When the user logs in for the first time, a signature verification key pair is generated through the public key authentication mechanism of asymmetric encryption. The private key of the signature verification key pair is arranged in the user end, and the public key is arranged in the platform end.

[0064] When the platform end responds to the target instance debugging request of the user end, the identity authentication signature signed by the user based on the private key is extracted from the debugging request, and the identity of the user is verified through the pre-deployed public key, so as to realize the rapid identity authentication of the user end. Since the identity authentication can be completed based on the identity authentication signature of the user end, the user does not need to repeatedly input the login information, thereby improving the management efficiency of the operating system instance.

[0065] Further, the first connection establishment unit 1002 is configured to, when the identity authentication result is passed, establish a bidirectional communication connection between the user end and the target node based on the Websocket protocol and the SSH protocol session, and the target node includes a target operating system instance.

[0066] In the conventional process of establishing a connection by using the SSH protocol, the SSH may need to re-establish a connection or rely on a polling mechanism at each data interaction, which will cause a delay in the transmission of debugging commands and data, thereby affecting the debugging and management efficiency of the operating system instance.

[0067] Compared with the SSH protocol, the Web socket protocol is a protocol for full-duplex communication on a single TCP connection, which allows both parties to send data at any time and can keep the connection state at any time. Therefore, by seamlessly integrating the Web socket protocol and the SSH protocol and establishing a bidirectional communication between the user end and the target node based on both, the transmission delay of data can be effectively reduced, the user can obtain a debugging experience similar to the conventional SSH terminal in the browser of the interactive terminal without the need to install additional plug-ins, thereby improving the management efficiency of the operating system instance.

[0068] Specifically, the core of the binding between the Web socket protocol and the SSH protocol session is to connect the data stream transmitted by the Web socket protocol with the input and output data of the SSH protocol session. The binding between the Web socket protocol and the SSH session can be understood as a bidirectional data pipeline. When the front-end Web socket protocol session receives a target debugging request from the user end, the request is converted by the Web socket protocol session into input data of the SSH protocol session and transmitted to the SSH protocol session. Similarly, the output data of the SSH protocol session is fed back to the Web socket protocol session in real time, and then converted by the Web socket protocol session and transmitted to the user end. The binding between the Web socket protocol session and the SSH protocol session can be regarded as a process of flow conversion mapping, that is, the input flow of the user is mapped to the input flow of the SSH protocol session through the Web socket protocol session, and the output flow of the SSH protocol session is mapped back to the output flow of the Web socket protocol session.

[0069] In actual application scenarios, the vehicle network cloud platform often receives operating system instance debugging requests from multiple user ends. In order to ensure that each user's debugging request can be responded to, an asynchronous I / O processing mechanism can be applied to ensure that each user's debugging request can be responded to in real time in a high-concurrency situation.

[0070] Specifically, the asynchronous I / O is similar to an event-driven transformation model, and an event loop-based framework can be used to process multiple parallel debugging requests. When the Web socket protocol session receives a debugging request from the user end, the debugging request is immediately transmitted to the SSH protocol session through an event-driven mechanism, and the output flow of the SSH protocol session is listened to based on the signal identifier of the debugging request. When the corresponding output flow is listened to, the corresponding result is fed back to the corresponding user end through the event mechanism. In this way, each debugging request and its corresponding response result are independently run, thereby improving the concurrent processing capability of the system for multiple debugging requests.

[0071] In a possible implementation, when the amount of data transmitted between the Web socket protocol session and the SSH protocol session is large, a frame sequence number-based fragmentation transmission and recombination algorithm can be used to divide the entire data into multiple data segments, and mark a sequence number for each data segment. The receiving end receives data according to the sequence number order of the data segments, thereby ensuring normal data transmission.

[0072] On the other hand, in order to ensure the communication security between the Web socket protocol session and the SSH protocol session, the data transmission security can be ensured by encryption through the TLS encryption algorithm of the Web socket protocol itself. At the same time, in order to improve the energy utilization efficiency of the system, the connection time between the Web socket protocol session and the SSH protocol session can also be monitored in real time, and when the connection time between the two exceeds the set threshold, the connection between the two is disconnected, thereby improving the resource utilization of the system.

[0073] The second connection establishing unit 2002 in the debugging processing module is configured to establish a WebRTC channel between the user end and the target operating system instance according to the bidirectional communication connection.

[0074] Unlike the Web socket protocol, the WebRTC protocol can provide more efficient real-time communication capabilities, which can establish a low-latency communication channel between the user end and the target operating system instance, thereby meeting the debugging needs of the user end for the target operating system instance. Therefore, in order to improve the management efficiency of the user end for the target operating system instance as much as possible, on the basis of the established bidirectional communication between the user end and the target node, a WebRTC channel between the user end and the target operating system instance also needs to be established, thereby reducing the communication delay between the two as much as possible and improving the debugging efficiency.

[0075] Specifically, when establishing the WebRTC channel, the connection information between the second connection establishing unit and the target operating system is exchanged through the signaling server. In the connection information of both parties, the candidate connection path and the media parameter are included, and the second connection establishing unit can search all possible connection paths between the target operating system instance through the ICE algorithm. Each candidate path is evaluated in turn by the ICE algorithm, and the path with the lowest delay and the best quality is selected for connection, thereby ensuring the data transmission performance of the WebRTC channel.

[0076] The debugging unit 2001 is configured to transmit the target instance debugging command to the target operating system instance through the WebRTC channel in response to the target instance debugging command for the target operating system instance from the user end, so as to debug the target operating system instance.

[0077] Finally, in the case where the WebRTC channel has been established between the user end and the target operating system instance, the target instance debugging command of the user end for the target operating system instance can be quickly transmitted to the target operating system instance through the WebRTC channel, thereby realizing the rapid debugging of the target operating system instance.

[0078] Specifically, in the process of transmitting the target instance debugging command by the debugging unit, in order to ensure the compatibility of the debugging command with the operating system of the target operating system instance, the debugging unit establishes an instance debugging session according to the operating system type of the target operating system instance. For example, Figure 2 When the target operating system instance is a Redroid instance running on an Android operating system, the corresponding instance debugging session established is an ADB session. The ADB session is displayed on the interactive terminal of the user end, and the user inputs the debugging command in the ADB session, thereby realizing the rapid debugging of the target operating system instance.

[0079] The above is the overall introduction of the management system of the operating system instance provided by the embodiments of the present application. Next, other units and modules involved in the system will be introduced from multiple aspects.

[0080] From the above description of the WebRTC channel, it can be known that when the second connection establishment unit establishes the WebRTC channel between the user end and the target operating system instance, it determines the connection path with the lowest delay and the best transmission quality through the ICE algorithm. Therefore, in order to ensure the transmission quality of the WebRTC channel in real time, the management system provided by the embodiments of the present application also sets a connection monitoring unit, which is specifically used to perform the following two steps:

[0081] Step one, monitoring the data transmission parameters of the WebRTC channel based on the RTCP protocol; the data transmission parameters include: data transmission rate and data transmission delay,

[0082] Step two, when at least one of the data transmission rate and the data transmission delay is lower than the corresponding preset threshold, replacing the WebRTC channel between the user end and the target operating system instance.

[0083] In actual application scenarios, the WebRTC channel transmits the debugging command and the result data fed back by the operating system instance through the RTP protocol. Therefore, the connection monitoring unit can monitor the data transmission rate and the data transmission delay in the WebRTC channel by combining the RTCP and the RTP protocol. When the data transmission rate or the data transmission delay in the channel is lower than the set threshold, other RTC channels can be adjusted and switched in time, thereby ensuring the real-time transmission and stability of the debugging command.

[0084] On the other hand, in actual vehicle networking cloud platforms, the debugging of each operating system instance is often performed by a debugging virtual machine in the cloud platform, and therefore the vehicle networking cloud platform often sets multiple debugging virtual machines.

[0085] In actual debugging scenarios, the debugging tasks for different operating system instances often have different task complexity. In order to ensure that the debugging virtual machines do not have excessive load when processing debugging tasks, the debugging processing module in the embodiments of the present application also has a load distribution unit for distributing debugging tasks to the virtual machines. The load distribution unit is specifically configured to perform the following three steps:

[0086] Step one, according to the real-time load data of each debugging virtual machine and a time series analysis algorithm, predicting the load of each debugging virtual machine to obtain the predicted load of each debugging virtual machine.

[0087] In the running process of the system, the load distribution unit collects the real-time load data of each debugging virtual machine in real time. The real-time load data of the debugging virtual machine includes the CPU usage, memory occupancy, network bandwidth, and I / O operation execution of the virtual machine. The real-time load data of each debugging virtual machine is transmitted to the load distribution unit in real time to facilitate the load distribution unit to distribute tasks.

[0088] When the load distribution unit receives the real-time load data of each debugging virtual machine, it predicts the load usage of each debugging virtual machine in the future through a time series analysis algorithm to obtain the predicted load of each debugging virtual machine, so as to subsequently distribute tasks according to the predicted load.

[0089] Step two, task analysis of the target instance debugging command to obtain the target debugging task complexity.

[0090] Step three, according to the target debugging task complexity and the predicted load of each debugging virtual machine, determining the debugging virtual machine for responding to the target instance debugging command.

[0091] Further, the load distribution unit analyzes the task of the target instance debugging command received in real time to determine the task complexity of the target debugging task. In this way, by the complexity of the debugging task and the predicted load of each debugging virtual machine, the debugging virtual machine with no excessive load in the future can be determined from multiple debugging virtual machines, and the debugging virtual machine is determined as the virtual machine for responding to the target instance debugging command, so as to ensure the load balance between multiple debugging virtual machines and improve the running stability of the system.

[0092] In actual application scenarios, when the target operating system instance responds to the target instance debugging command, it needs to feed back the corresponding response log to the user end through the WebRTC channel. When multiple debugging commands exist at the same time, there will be too many logs, which will cause difficulty in displaying the logs.

[0093] Therefore, in order to solve the above problems, in the management system provided by the embodiment of the application, a special log management module is further arranged. Among them, the display management of the log is controlled by the log display unit in the log management module, and the log display unit is mainly used to execute the following two steps:

[0094] Step one, based on the stream processing algorithm, the output log of the target operating system instance is analyzed to extract the first log data stream from the output log.

[0095] In the display stage of the log, in order to ensure that the latest log of the target operating system instance can be displayed, the input log of the target operating system instance needs to be analyzed based on the stream processing algorithm to extract the latest generated log and obtain the first log data stream.

[0096] Step two, according to the sliding window algorithm and the log display item threshold, the first log data stream is displayed in the form of a sliding window on the interactive terminal of the user terminal.

[0097] Correspondingly, in the process of displaying the newly generated first log data stream to the user terminal, in order to avoid the interface information display overload of the user terminal and ensure that the log can be updated and displayed in real time, the display items of the log need to be reduced to below the item threshold by the sliding window algorithm and the log display item threshold of the user terminal, and the displayed log is updated by the sliding window method, so as to ensure that the real-time updated log can be displayed on the display interface of the user terminal.

[0098] In addition, in the process of controlling the log display, the first log data stream fed back by the target operating system instance often includes many logs irrelevant to the user demand. In order to ensure the display quality of the log, the log filtering unit is further arranged in the embodiment of the application, which is used to filter the useless or garbage log files in the first log data stream after obtaining the first log data stream, so as to optimize the effect of log display and reduce the loss of storage resources. Specifically, the log filtering unit is used to execute the following two steps:

[0099] Step one, according to the preset log filtering keyword and the Bloom filter, the hash result of the log in each log file in the first log data stream is calculated to obtain the hash result of each item log.

[0100] Step two, if the hash result of the log in the log file is not equal to the preset value, the log file is filtered, and after the filtering of the first log data stream is completed, the second log data stream is obtained.

[0101] After obtaining the first log data stream, the log filtering unit may calculate a hash result for the log files in the first log data stream based on a preset log training filter and a Bloom filter, and perform log filtering according to the actual hash result.

[0102] Specifically, for each log entry in the log file, the log filtering unit needs to calculate the hash result of the log using a hash function. Assuming the default value is 1, if the hash result corresponding to all log entries in the log file is 1, the log file is considered to meet the conditions. Otherwise, if there is a log entry with a hash result other than 1, the log file is filtered to ensure the data quality of the log data stream.

[0103] Bloom filters use multiple independent hash functions to map elements to bit arrays. Their core principle is to quickly determine the existence of elements by combining the sparsity of the bit array with the probability of hash collisions. For large-scale log data, this algorithm significantly reduces storage and computing resource consumption.

[0104] In one possible implementation, in order to improve system resource utilization and prevent repeated downloading and storage of logs, a log storage unit is further provided in the above-mentioned log management module, and the log storage unit is used to perform the following two steps:

[0105] Step 1: In response to the log download request from the user terminal, a target download log is determined according to the log download request and the downloaded logs; the target download log is a new log added to the downloaded logs.

[0106] Step 2: perform incremental compression on the target download log using an incremental compression algorithm to obtain a target compressed log, and merge the target compressed log with the downloaded log for storage.

[0107] When the log storage unit responds to the log download request from the user end, it determines the logs that have been previously downloaded and stored through the log download request, so as to determine which logs are previously downloaded and which are newly downloaded after the last download, and determine this type of log as the target download log.

[0108] After identifying these newly added logs, the newly added target logs are incrementally compressed using an incremental compression algorithm and compressed into previously downloaded log files. This can reduce the transmission and storage of duplicate data, reduce bandwidth consumption and download time, and thus optimize the utilization efficiency of network resources.

[0109] In addition, the system can also dynamically adjust the storage strategy of the log according to the access frequency of the user terminal to the log, for example, the log with high access frequency can be stored in a fast access storage device, and the low frequency or expired log can be transferred to a slow storage or archive, so as to dynamically allocate the storage resources of the system by analyzing the usage of the log, and improve the resource utilization of the system.

[0110] The embodiment of the application provides a management system of an operating system instance, which is applied to a vehicle Internet cloud platform and specifically comprises a node management module and a debugging processing module, wherein the node management module is provided with an identity authentication unit and a first connection establishment unit, and the debugging processing module is provided with a second connection establishment unit and a debugging unit.

[0111] When the user terminal needs to debug the operating system instance in the vehicle Internet cloud platform, the target instance debugging request of the user terminal is responded by the identity authentication unit, so as to verify the identity authentication signature of the user terminal. Since the identity authentication signature of the user terminal is generated based on the signature verification key of the vehicle Internet cloud platform, the user only needs to verify once to access all nodes and operating system instances in the vehicle Internet cloud platform, thereby avoiding the repeated login problem involved in the application of the traditional SSH login, and improving the management efficiency of the operating system instance. Further, when the identity authentication signature of the user terminal is passed, on the basis of the traditional SSH protocol, the Web socket protocol and the SSH protocol session are combined to establish a bidirectional communication connection between the user terminal and the target node, so as to ensure the low-delay interaction between the user terminal and the target node, thereby simulating a complete debugging interaction environment through seamless integration between the Websocket protocol and the SSH protocol, so that the user can obtain similar experience to the traditional SSH terminal in the browser, and the management efficiency of the operating system instance is further improved. Finally, on the basis that the bidirectional communication between the user terminal and the target node has been established, the WebRTC channel between the user terminal and the target operating system instance is established through the bidirectional communication between the two, and the debugging of the user terminal to the target operating system instance is realized based on the WebRTC channel, so that the user terminal can remotely debug the operating system instance by using the real-time communication capability of WebRTC, and the management efficiency of the operating system instance is improved in multiple aspects.
