Description

Technical Field

[0001] The invention belongs to the technical field of electronic equipment, and in particular relates to a VPX chassis system supporting IPMB and SNMP integration. Background Art

[0002] VPX chassis are increasingly used in the military and aerospace fields. Their high reliability and high performance make them indispensable components in these fields. The key role of network management in VPX systems cannot be ignored. It not only ensures the stable operation of the system, but also improves the maintainability and fault response speed of the system. As an advanced hardware monitoring and management method, IPMB technology provides strong support for VPX chassis with its basic functions and architecture. SNMP technology is a protocol widely used in network device management. Its basic functions and architecture provide a standardized solution for network management of VPX chassis.

[0003] In existing VPX chassis management solutions, IPMB and SNMP each play an important role, but their integrated application faces many challenges. In the existing attempts to integrate IPMB and SNMP, the focus is mainly on how to effectively merge the data exchange and control mechanisms of the two protocols. These solutions usually involve the development of specific middleware or gateway devices to achieve data conversion and command forwarding between the IPMB bus and the SNMP network. However, these attempts often face compatibility issues because IPMB and SNMP have significant differences in data format, communication protocol and operation logic. In addition, these integration solutions may encounter performance bottlenecks when dealing with large-scale VPX chassis networks, resulting in inefficient management and delayed response time. Therefore, although there have been some preliminary integration attempts, there is still a lack of an efficient, stable and compatible IPMB and SNMP integration solution on the market. Summary of the invention

[0004] To solve the above problems, the present invention provides a VPX chassis system supporting IPMB and SNMP integration, including:

[0005] Chassis: Multiple slots are built in for access to network devices, functional modules, IPMB interfaces and SNMP interfaces. The IPMB interface is mainly used for monitoring and management of modules inside the chassis, providing real-time data of key parameters such as temperature, voltage and fan status. The SNMP interface is used for external network management, allowing remote monitoring and configuration of the VPX chassis. Each slot is connected via a high-speed backplane to improve data transmission efficiency.

[0006] Data processing module: responsible for collecting data from IPMB interface and SNMP interface;

[0007] Protocol conversion module: used to realize data format conversion, convert IPMB data format into a format recognizable by SNMP, and convert SNMP data format into a format recognizable by IPMB;

[0008] User interface module: provides an intuitive graphical interface to facilitate users to monitor and manage the system;

[0009] Alarm processing module: automatically triggers alarms and takes corresponding measures based on preset thresholds.

[0010] Furthermore, the protocol conversion module uses a bridge chip to process both IPMB and SNMP protocols, ensuring real-time communication and data exchange between the two IPMB interfaces and the SNMP interface. The built-in protocol parser in the chip can identify and parse commands and data from the IPMB interface, which usually contain device status information and control instructions. The parsed data is converted into a standard format that the SNMP protocol can understand, a process that involves the reorganization of the data structure and necessary information mapping.

[0011] Furthermore, when the data conversion is implemented, an algorithm is used in the bridge chip to encrypt the data, and MD5 or SHA-256 is used to encrypt the data.

[0012] Furthermore, the bridge chip uses CRC check to verify data integrity.

[0013] Furthermore, when the protocol conversion module realizes the conversion of data formats, the transmission path of the data packet can be dynamically adjusted according to the real-time status of the network and the data flow, thereby optimizing network performance and reducing delays. This intelligent routing mechanism not only improves the efficiency of data transmission, but also enhances the stability and reliability of the network.

[0014] Furthermore, the communication protocol used for data transmission in the VPX chassis system supports real-time data transmission and historical data recording, and has an error detection and correction mechanism. The communication protocol used is the SNMP protocol.

[0015] The present invention has the following beneficial effects:

[0016] 1) Improve network management efficiency: Through the integration of IPMB and SNMP, the VPX chassis system can achieve efficient monitoring and management of network devices, reduce manual intervention, and improve management efficiency;

[0017] 2) Enhanced fault diagnosis capability: The integrated system can collect and analyze the status information of network devices in real time, quickly locate the fault point, and shorten the fault recovery time;

[0018] 3) Improve system reliability: Through the SNMP protocol, the system can monitor the operating status of network devices, discover potential problems in a timely manner, prevent system failures, and improve the reliability of the entire network system;

[0019] 4) Simplified configuration management: The integration of IPMB and SNMP enables the system to uniformly manage the configuration of network devices, simplify the configuration process, and reduce configuration errors;

[0020] 5) Support remote management: Using the remote management function of SNMP, users can remotely monitor and control VPX chassis network devices without on-site operation, improving management flexibility; BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The invention provides a VPX chassis system supporting the integration of IPMB and SNMP.

[0026] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings.

[0027] Figure 1 A schematic diagram of a technical implementation framework provided according to an embodiment of the present invention is provided, as shown in the figure, including:

[0028] Chassis: Multiple slots are built in for access to network devices, functional modules, IPMB interfaces and SNMP interfaces. The IPMB interface is mainly used for monitoring and management of modules inside the chassis, providing real-time data of key parameters such as temperature, voltage and fan status. The SNMP interface is used for external network management, allowing remote monitoring and configuration of the VPX chassis. Each slot is connected via a high-speed backplane to improve data transmission efficiency.

[0029] Data processing module: responsible for collecting data from IPMB interface and SNMP interface;

[0030] Protocol conversion module: used to realize data format conversion, convert IPMB data format into a format recognizable by SNMP, and convert SNMP data format into a format recognizable by IPMB;

[0031] User interface module: provides an intuitive graphical interface to facilitate users to monitor and manage the system;

[0032] Alarm processing module: automatically triggers alarms and takes corresponding measures based on preset thresholds.

[0033] In specific implementation, the VPX chassis system is running, and the IPMB interface monitors the network devices in the chassis. When the value of a device exceeds the threshold preset by the alarm processing module, an alarm is automatically triggered and corresponding measures are taken: for example, shutting down the device and starting cooling;

[0034] The device data collected by the IPMB interface through the IPMB protocol is converted by the protocol conversion module and transmitted to the SNMP interface. The data processing module collects data from the SNMP interface and transmits the data to the server through the SNMP protocol.

[0035] Users can remotely view and manage the data of each device through the user interface module on the server.

[0036] The instructions sent by the server are received by the SNMP interface, converted by the protocol conversion module and passed to the IPMB interface to control the device.

[0037] Furthermore, the protocol conversion module uses a bridge chip to process both IPMB and SNMP protocols, ensuring real-time communication and data exchange between the two IPMB interfaces and the SNMP interface. The built-in protocol parser in the chip can identify and parse commands and data from the IPMB interface, which usually contain device status information and control instructions. The parsed data is converted into a standard format that the SNMP protocol can understand, a process that involves the reorganization of the data structure and necessary information mapping.

[0038] The IPMB message format is as follows Figure 2 As shown, the SNMP message format is as follows Figure 3 shown.

[0039] Furthermore, when the data conversion is implemented, an algorithm is used in the bridge chip to encrypt the data, and an MD5 algorithm or a SHA-256 algorithm is used to encrypt the data.

[0040] Furthermore, the bridge chip uses CRC check to verify data integrity.

[0041] Encryption and verification measures can effectively prevent data from being tampered with or stolen during transmission, ensuring the security of network management.

[0042] Furthermore, when the protocol conversion module realizes the conversion of data formats, the transmission path of the data packet can be dynamically adjusted according to the real-time status of the network and the data flow, thereby optimizing network performance and reducing delays. This intelligent routing mechanism not only improves the efficiency of data transmission, but also enhances the stability and reliability of the network.

[0043] Furthermore, the communication protocol used for data transmission in the VPX chassis system supports real-time data transmission and historical data recording, and has an error detection and correction mechanism. The communication protocol used is the SNMP protocol.

[0044] The main functions and effects of the SNMP protocol: It provides a method for collecting network management information from devices on the network. The device manager collects this information and records it in the Management Information Base (MIB), reporting the device's characteristics, data throughput, communication overload and errors, etc.; it allows the management station to configure the parameters and properties of network devices, such as modifying the device's IP address, port number, access control list and other configuration information; it allows the management station to set alarm rules, and when the performance or status of the network device is abnormal, the SNMP agent will send an alarm message to the management station; SNMP also provides a way for devices to report problems and errors to the network management workstation; the logical structure of the SNMP protocol is as follows: Figure 4 shown.

[0045] Through the present invention, the fault diagnosis capability can be enhanced: the status information of network equipment can be collected and analyzed in real time, the fault point can be quickly located, and the fault recovery time can be shortened; the system reliability can be improved: through the SNMP protocol, the system can monitor the operating status of network equipment, discover potential problems in time, and prevent system failures; the configuration management can be simplified: the integration of IPMB and SNMP enables the system to uniformly manage the configuration of network equipment, simplify the configuration process, and reduce configuration errors; remote management is supported: using the remote management function of SNMP, users can remotely monitor and control VPX chassis network equipment to improve management flexibility.

[0046] The above disclosures are only several specific embodiments of the present invention; however, the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
