Method for communicating data between locally networked heterogeneous processing systems and communication system using said method

摘要

A method for communicating data in an aircraft between at least a first data processing system and a second data processing system locally networked, each processing system being capable of executing at least one application, wherein the data to be exchanged are organized in messages, the aforementioned messages as well as the processing systems and the applications being defined in files stored in a backup unit connected to the network and accessible by the data processing systems.

1. A method for data communication in an aircraft between at least a first data processing system and a second data processing system connected in a local network, with each processing system being able to execute at least one application, the method comprising:
exchanging data between the data processing systems by means of messages circulating in the local network and all messages having a unique configuration, these messages and the processing systems and the applications being described in files in memory in a centralized backup unit connected to the local network, the memory being dedicated solely to configuration of data utilized by the data processing systems, and accessible by each of the data processing systems, receiving a message with one of the data processing systems such that the data processing system receiving the message is able from information furnished in the message to retrieve in the backup unit files the data corresponding to the message, wherein the message includes a unique identity information of the message and a length information of the message, and reducing a size of the message based on the length information for controlling a bandwidth of the local network during the data communication.
