Satellite-borne equipment system for service traffic control and differentiated services

Abstract

The invention discloses a system for performing service traffic control and differentiated services between satellite-borne equipment, relating to the field of satellite communication based on on-board processing. The system consists of a rate identification module, a token bucket module, a transmission processing module, a queue management module and a transmission scheduling module of satellite-borne equipment A, a rate analysis module, a receiving processing module and a data FIFO module of satellite-borne equipment B, and other parts, wherein the rate analysis module and the rate identification module analyze remote control instructions and set protocols to obtain rate information; the token bucket module is used to implement service traffic shaping and control functions; the queue management module and the transmission scheduling module implement multi-level priority queue management and output scheduling; the data FIFO module implements data cache management; and the transmissionprocessing module and the receiving processing module realize data transfer and output. The system disclosed by the invention has the advantages of supporting traffic control between the satellite-borne equipment, supporting the differentiated services, achieving strong scalability and less resource occupation, and the like, and is especially suitable for satellite communication systems based onon-board processing.

Description

technical field [0001] The invention relates to a system for controlling traffic flow between satellite-borne devices and distinguishing services, which belongs to the field of on-board processing of satellite communication systems. Background technique [0002] Conventional transparent transponders, also known as bent-pipe transponders, are widely used because of their simple structure and reliable performance when satellite payloads and power supplies are limited. However, with the development of satellite communication technology, the increase of business volume and the improvement of communication quality requirements, the satellite communication system spectrum utilization rate, system capacity, communication quality, network connectivity, communication link efficiency, dynamic reorganization ability of the network and Strict and urgent requirements are put forward for anti-interference performance and other aspects. With the advancement of technology and the change of ...
