Problems solved by technology

This method has many steps and needs to transmit messages between the edge gateway and the home gateway multiple times, resulting in long delay and low efficiency.
[0005] If the broadcast method is used, it will increase invalid network traffic, causing the edge gateway to receive a large number of useless messages, which will effectively flood the real needs of its processing, greatly reducing the processing efficiency of the edge gateway, and occupying a large amount of network traffic. bandwidth, which is also not conducive to aviation information security

Embodiment Construction

[0022] In the gateway cluster, three methods of multi-address, aggregated address, and mandatory address are used for multi-point delivery: multi-address means that there are several addresses in the address item in the application layer transmission information packet, and the information is delivered to different addresses according to different addresses. Aggregate address refers to the use of certain addresses to represent a group of addresses, such as airlines and all subsidiaries, etc., according to which information is delivered to all places in this group of addresses; mandatory addresses are certain addresses that must receive certain reports. For example, the general dispatching room needs to receive all messages, etc. These addresses are set with static routes in the host gateway, so that they can be delivered according to the settings.

[0023] The downlink message of the gateway cluster is carried out in the host gateway, and the delivery strategy of the host gatew...

Abstract

The down message multipoint delivering method for aviation gateway colony system includes the following steps: judging the effectiveness of the message, and extracting message address, tail number and message characteristic; judging whether to need forced delivery, and if so, adding corresponding boundary gateway address label in front of the message header; judging whether to need fixed delivery, and if so, adding corresponding boundary gateway address label in front of the message header and delivering directly; judging whether to need delivery based on the tail number, and if so, adding corresponding boundary gateway address label in front of the message header; judging whether to need delivery based on service, and if so, adding corresponding boundary gateway address label in front of the message header; and copying message based on the address label, and delivering to the boundary gateway. The present invention has high efficiency and less bandwidth consumption.

Description

technical field [0001] The invention relates to a message delivery method for an aviation system, in particular to a multi-point delivery method for downlink messages of an aviation gateway cluster system, and belongs to the technical field of aviation communication. Background technique [0002] In the aviation gateway communication system, such as figure 1 As shown, each aviation private network communicates with the host gateway through an edge gateway, and connects each aviation private network and ground-air data network through the edge gateway and host gateway. Between each aviation private network, each aviation private network passes ground-air data network The aeronautical message is transmitted between the network and the aircraft, thereby realizing the convenient communication of the entire aviation system; since each aviation-specific telecommunication network communicates with the host gateway, all information is concentrated in the host gateway, which brings g...
