Problems solved by technology

[0003] In application environments such as navigation, aerospace, etc., FC node devices or switching devices are fixedly installed in the integrated device rack, and it is extremely difficult to disassemble. When the software and firmware need to be updated, the device must be disassembled and the cover opened. This process will inevitably cause irreversible damage to the system, reducing the seismic performance and service life of the system

Embodiment Construction

[0030] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose, the following is a detailed implementation of a remote upgrade method for the entire network based on the FC switching network proposed according to the present invention in conjunction with the accompanying drawings and preferred examples , structure, feature and effect thereof, detailed description is as follows.

[0031] see Figure 1 to Figure 4 The present invention provides a method for remotely upgrading the entire network based on an FC switching network. The firmware of all devices in the FC switching network (ie, the target FC node device) is updated through an FC (Fiber Channel) firmware update device, and has multiple nodes. The ability to update devices simultaneously.

[0032] The FC firmware updating device includes a host computer, an FPGA chip, a photoelectric transceiver, a power supply chip and a storage chip. The upper ...

Abstract

A method for remotely upgrading the entire network based on an FC switching network, which uses an FC (Fiber Channel) firmware updating device to update a target FC node device in the FC switching network; the FC firmware updating device includes a host computer, an FPGA chip, and a photoelectric transceiver; Before the remote update, the upper computer needs to send the secret key information to each target FC node device in order to log in and open the update function of each target FC node device. Sending of information; the remote upgrade method of the whole network based on FC switching network of the present invention can improve the security, reliability and maintainability of the system, can quickly update the firmware of the node equipment in the FC network and prevent abnormalities caused by the network or outside the network The data frame injection causes the Flash Memory to change, causing the firmware of the node device to be updated unexpectedly or even damaged.

Description

technical field [0001] The invention belongs to the technical field of FC-AE optical fiber channel, and in particular relates to a method for remotely updating the entire network based on an FC switching network. Background technique [0002] As a new fiber channel technology, FC-AE has the characteristics of high bandwidth, low delay, high reliability, and high anti-interference. It has been widely used in high-reliability fields such as navigation and aerospace. The FC network of the AE-ASM protocol has been used as the backbone communication network. [0003] In application environments such as navigation, aerospace, etc., FC node devices or switching devices are fixedly installed in the integrated device rack, and it is extremely difficult to disassemble. When the software and firmware need to be updated, the device must be disassembled and the cover opened. This process will inevitably cause irreversible damage to the system, reducing the seismic performance and servic...
