Description

Technical Field

[0001] The present invention belongs to the technical field of software deployment, and in particular relates to a system software deployment and verification method and system based on a directional distribution mechanism. Background Art

[0002] The widespread adoption of informatization and digitalization has driven the widespread use of server cabinets. Server cabinets are generally divided into three levels: the cabinet, the chassis, and the boards. The boards belong to the chassis and plug into its slots; the chassis belongs to the cabinet and is installed in the cabinet's rotating cage. The processing functions of the server cabinet are performed by the software within the boards. The number of software programs within a server ranges from dozens to hundreds. This is especially true for large-scale distributed server cabinet clusters. The traditional manual, point-to-point program loading method is not only inefficient, but also lacks automatic verification after software deployment, resulting in an uncertain success rate and no longer meeting practical needs. Therefore, an efficient communication mechanism is needed to replace the point-to-point model, while also adding a software package verification mechanism to ensure the success rate of software deployment.

[0003] DDS (Data Distribution Service) is a next-generation, data-centric communications middleware technology. Utilizing a publish / subscribe mechanism, DDS is optimized for distributed data exchange with low latency and high throughput, meeting the requirements of a wide range of distributed communications applications. This makes it widely applicable in defense, aviation, simulation, industrial automation, and other fields, including the Aegis Open Architecture, the Ship Self-Defense System, and the Littoral Combat Ship. DDS's data-centric publish / subscribe model eliminates coupling, offering excellent distributed data distribution characteristics and exceptional capabilities for handling complex data flows in distributed systems. DDS is reliable and fault-tolerant, supporting multiple reliability mechanisms to ensure reliable data transmission. Furthermore, DDS automatically detects and recovers from network or node failures, ensuring system stability.

[0004] MD5 (Message-Digest Algorithm 5) is a widely used cryptographic hash function that is irreversible, deterministic, and fast. MD5 is a one-way hash function that generates a hash value of fixed length (128 bits) by operating on messages of arbitrary length. The original message content cannot be reversely deduced from the generated hash value, which provides high security. For the same input information, MD5 always generates the same hash value. This feature makes it suitable for verifying data integrity. For example, in scenarios such as file transfer and data storage, the MD5 code of a file can be compared to determine whether the file is damaged or tampered with. MD5 is relatively fast to calculate and can process large amounts of data in a short period of time.

[0005] Chinese patent document CN105867934B proposes a remote file upgrade method based on binary search and MD5 checksums, and Chinese patent document CN1 12367171B proposes a data transmission method and component based on RSA and MD5. Both of these methods lack the convenience of methods based on the DDS communication mechanism. Therefore, the combination of DDS and MD5 offers a more efficient and reliable approach and method for distributed software deployment, and has broad application prospects compared to traditional point-to-point software deployment methods. Summary of the Invention

[0006] The present invention aims to provide a system software deployment and verification method and system based on a targeted distribution mechanism, thereby improving the accuracy and security of software deployment and avoiding the risk of misdeployment.

[0011] S4. The proxy service software runs in the distributed system to be deployed. The proxy service software is set to the system auto-start state. When the system is turned on, the proxy service software also starts running.

[0012] S5. The display and control service software receives the system status information reported by the proxy service software: after starting, the proxy service software obtains the status information of the distributed system in which it is located, and reports the status information to the display and control service software through DDS;

[0013] S6. The display and control service software issues a system software deployment command: the display and control service software issues a software deployment command after receiving the status information reported by the proxy service software;

[0015] S8, the proxy service software feeds back the verification result to the display and control service software via DDS for display and processing;

[0016] S9. The display and control service software receives and analyzes the software verification information. If the verification result is successful, the deployment is completed; otherwise, for the failed software, the corresponding software is selected again for secondary deployment based on the status information of the proxy service software.

[0045] The status information in S5 is status information of the cabinet number, chassis number, and slot number.

[0046] In S7, when the agent service software receives the software package sent by the display control service software, it first determines whether the value of the status information carried by the system software in the software package is consistent with the current system.

If they are consistent, the verification passes, and the verification success information is fed back to the display and control service software, otherwise the verification failure information is fed back to the display and control service software.
