On-board network system and backbone node message processing method thereof

Abstract

The invention discloses an on-board network system and a backbone node message processing method thereof. In the system, a mixed layered network structure of combining a ratio Mesh backbone network and a heterogeneous access network is adopted, and the interconnection of various access networks is realized through an on-board backbone network, thereby the flexibility and the expandability of the system are improved. Meanwhile, a backbone node message processing method is adopted in the comprehensive message processing system of backbone network nodes. The method realizes the transformation of heterogeneous messages between a core network and an edge network, and a publishment/subscription mechanism based information distribution service is adopted, thereby the resource utilization ratio and the information access efficiency in complicated network environment are improved. The invention has military and civil values and particularly has wide application prospects in the fields of airborne command collaborative constellation of military integration information grids, civil aviation networked communication, navigation, monitoring, and the like.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to an airborne network system and a backbone node message processing method thereof. Background technique [0002] Airborne Network (AN) is a wireless communication network that uses aircraft as nodes and is interconnected by wireless data links to transmit packet messages and IP services. Especially in the integrated information grid system, AN is an air tactical information network with the integrated avionics system as the main node. Changes in the situation dynamically form a matching topology, providing real-time, reliable, and flexible information sharing for air system confrontation. At the same time, AN can be used as the air relay system of the regional communication network, which can not only overcome the influence of the terrain, expand the communication range, but also have shorter delay and more flexible deployment compared with satellite communicatio...

Problems solved by technology

[0008] (4) Bandwidth is limited and variable

[0010] Due to the constraints of platform load and channel environment, the airborne network system has been unable to meet the rapidly increasing bandwidth requirements of various services

Since the general communication network does not have the ability to identify user awareness and lacks the control and scheduling of transmission information, the quality of communication services is significantly reduced, making it difficult to distribute time-sensitive survivability information in a timely manner.
