Whole-network remote upgrading method based on FC switching network

Abstract

The invention discloses a whole-network remote upgrading method based on an FC (Fiber Channel) switching network. The method comprises the following steps: updating target FC node equipment in the FC switching network through an FC firmware updating device, wherein the FC firmware updating device comprises an upper computer, an FPGA chip and a photoelectric transceiver, the upper computer needs to send secret key information to each target FC node device before remote updating so as to log in and open an updating function of each target FC node device, and the upper computer starts to send firmware information after receiving a firmware updating function opening return packet of each target FC node device. According to the whole-network remote upgrading method based on the FC switching network, the safety, reliability and maintainability of the system can be improved, the firmware of the node equipment in the FC network can be rapidly updated, and the situation that the firmware of the node equipment is accidentally updated and even damaged due to the fact that Flash Memory is changed due to injection of abnormal data frames in the network or outside the network is prevented.

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...
