Example Embodiment

[0024] The present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0025] For dual-fiber communication network systems, redundancy management is a method to effectively eliminate redundant data frames without wasting system resources while improving system reliability. figure 2 A redundancy management system for network terminal nodes in a dual fiber channel network communication system is presented. From figure 2 It can be seen that the sending end of the redundancy management system includes a redundancy code insertion module, and each fiber channel receiver includes an independent integrity check module, a data buffer module, and a redundancy management module.

[0026] For a single fiber channel network, the FC terminal determines the uniqueness of the data frame transmission in the network through the destination address ID (D_ID) and the exchange sequence number ID (OX_ID) in the data frame header. At the same time, th...

Abstract

The invention provides a redundancy management method for a double optical fiber channel network communication system. The redundancy management method comprises a redundant code insertion module, an integrity check module, a data buffer module and a redundancy management module. The redundant code insertion module is used for creating FC frames and simultaneously sending each FC frame through two optical fiber channels of an FC terminal; the integrity check module is used for checking the two FC frames according to source addresses in the FC frames and an exchange sequence number index receiving source sequence number table after the FC terminal receives the FC frames sent through the two optical fiber channels, and storing the qualified FC frame in the data buffer module; and the redundancy management module is used for transmitting the FC frame arriving at the data buffer module firstly to the upper layer according to the principle of first come first win. The redundancy management method provided by the invention is reliable, efficient to achieve redundancy management on the FC frames, and is compatible with single optical fiber channel network systems.

Description

technical field [0001] The invention relates to a dual-redundancy fiber channel (FiberChannel) network communication system, aiming at the characteristics of the avionics dual-machine redundant communication system, and proposes an efficient and reliable fiber channel redundancy management method. Background technique [0002] With the continuous development of avionics technology, the Aviation Anonymous Message Protocol (FC-AE) of Fiber Channel (FC) technology has been widely used and developed. figure 1 Shows the dual-fiber network system structure. [0003] In modern advanced avionics systems, the bandwidth requirements and reliability requirements for communication systems are getting higher and higher. Although Fiber Channel can meet the requirements of system communication bandwidth, the Fiber Channel protocol (FC-FS-2) itself has no relevant description for the application of redundant communication systems. Contents of the invention [0004] In order to realize c...
