Abstract

The present invention provides a space-based data link onboard message scheduling method and device, which belong to the field of space-based data link. The method includes: receiving a space-based data link onboard message, and dispatching said Messages are queued into different queues; according to the service types of the received messages, the extraction order and resources to be allocated corresponding to the messages are determined; according to the determined extraction order, messages of the same service type in each of the queues are extracted; Determine the resources to be allocated and schedule the extracted messages. The invention realizes the balanced processing of various types of messages in each queue, not only improves the utilization rate of the channel, but also improves the fairness among the queues, and improves the overall service capability of the network.

Description

technical field

[0001] A space-based data link spaceborne message scheduling method and device of the present invention belong to the technical field of space-based data link. Background technique

[0002] Related message scheduling methods for data links usually include the following:

[0003] (1) The message scheduling method of the ground traditional data link: in the ground traditional data link, the terminal machines have a peer-to-peer composition structure, and each terminal machine sends messages in the exclusive time slot allocated during planning, in the form of broadcasting, and The terminal machine can receive the message sent by the terminal machine. In this method, there is no autonomous message scheduling between terminals, and the timing and cycle of sending messages are completed through pre-planned tasks. For a single terminal, messages are sent in a first-in-first-out manner, that is, FIFO;

[0004] (2) Tactical data link dynamic polling scheduling algo...
