Embodiment Construction

[0032] In order to further clarify the implementation manner of the present invention, the specific implementation manner is further described with examples in conjunction with the accompanying drawings.

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] refer to Figure 1-Figure 3 , the present invention aims at the problems of low transmission efficiency and inability to guarantee the service quality of different grades of application software in the airborne environment during file transmission, and based on the short message channel and long message channel mechanism of the airborne network, a support determination method is proposed. A revolutionary airborne high-performance file transfer system implementation method.

[0035] The current airborne network supports short message channel and long message channel mechanism. The short message channel is a channel that can only transmit KB-level mes...

Abstract

The invention provides a deterministic airborne high-performance file transmission method and system, the system comprises a server and at least one client, and at least one application software runson the client; a long message channel and a short message channel are arranged between the server and the client; by utilizing a distributed priority scheduling control mechanism based on static configuration, the file transmission service quality of different security level applications is ensured; and by utilizing the characteristic that an airborne network resource short message channel and a long message channel coexist, a message is controlled to pass through the short message channel, a data message passes through the long message channel, a response message transmission protocol is simplified, and the file transmission performance is improved. Short and long message resources are fully utilized, a transmission protocol response message is simplified, the file closing frequency is reduced, data copying is reduced, and the airborne file transmission efficiency is improved; and through the priority round-robin scheduling of the client and the server, the transmission service quality of applications with different security levels is ensured.

Description

technical field [0001] The invention belongs to the technical field of computer system software, and relates to a deterministic airborne high-performance file transmission method and system. Background technique [0002] The new generation of distributed avionics system adopts the design concept of distributed, integrated, and modularized, and realizes the integration of avionics system functions through resource sharing. Data management integration (centralized and unified management of file data) is a comprehensive important aspect. [0003] Traditional file transfer protocols, such as TFTP and FTP, are file transfer protocols designed for high-latency, low-reliability, and general-purpose networks. They cannot meet the requirements of the airborne field in terms of supporting determinism and high performance. Contents of the invention [0004] The purpose of the present invention: to propose a deterministic airborne high-performance file transmission method and system,...
