Large-queue message transmission independence implementation method based on optical fiber channel

Abstract

The invention belongs to the field of avionics system airborne networks, and relates to an FC (Fibre Channel) large queue message transmission independence realization method. An FC message sending mechanism is formulated, an FC message sending API interface used for sending application data is included, and the method comprises: extracting application information and application data, obtaining FC sending communication information, assembling the application information and the application data into FC data, assembling an FC data frame, sending the FC data frame and the like. The invention further provides an FC message receiving mechanism. The FC message receiving mechanism comprises an FC message receiving API interface used for receiving application data, analyzing FC data, constructing API interface output parameters and the like. According to the invention, the system application message transmission is independent from the FC network topology structure, the network configurationand the message transmission, i.e., the changes of the system application message planning, the scale and the like are irrelevant to the FC network topology structure, the network configuration and the message transmission.

Description

technical field [0001] The invention belongs to the field of airborne networks of avionics systems, and relates to a method for realizing the independence of FC (Fiber Channel, Fiber Channel, FC for short) large queue message transmission. Background technique [0002] The on-board communication network of the avionics system of the existing model aircraft adopts the FC network, and the message communication and interaction between the subsystems of the avionics system are realized through FC. For existing aircraft model projects, the system uniformly plans the application message ID for communication between subsystems. The FC network needs to build a network topology based on the application message ID and generate corresponding FC network configuration data. When the subsystem uses FC to send messages, it calls the API interface function provided by FC, and passes the subsystem application message ID to FC as the input parameter of the function. FC, firstly, according t...

Problems solved by technology

If the system application message ID changes, it will affect the change of FC network topology and configuration data, which will lead to the upgrade of FC network

[0005] (2) It is not conducive to the management and maintenance of the technical status of the model project, and the application message ID of the system planning needs to be one-to-one correspondence with the FC network topology and configuration data

When the system application message ID is inconsistent with the FC network topology and configuration data, it will affect the communication between subsystems, which is not conducive to the management and maintenance of on-site technical status
