Congestion management suitable for wideband satellite communication system

Abstract

The invention discloses a congestion management method suitable for a broadband satellite communication system, which relates to the congestion management technology of the broadband satellite communication system in telecommunication field. The invention provides the proposal design of the system congestion management function and provides a configuration requirement on the buffer capacity of the satellite equipment from the aspects of satellite-ground congestion management function distribution, bandwidth resource distribution type, priority level design and congestion control measures based on the application and technology characters of broadband satellite communication system. The invention mainly uses pre-arranged bandwidth resource plan and distribution, adopts satellite equipment configured with large buffer to simplify the congestion control measures between satellite equipment and ground equipment, and effectively solves the design conflict between the quality of service of the system and the utilizing ratio of the bandwidth resource. The congestion management method suitable for a broadband satellite communication system of the invention has the advantages of simplifying the complexity of satellite equipment, enhancing the system running stability, and increasing the quality of service and the bandwidth resource utilizing ratio of the system. The congestion management method suitable for a broadband satellite communication system of the invention is especially suitable for the node-interconnected broadband satellite communication system.

Description

technical field [0001] The invention relates to a congestion management method suitable for broadband satellite communication systems in the communication field, and is particularly suitable for congestion management of broadband satellite communication systems oriented to node interconnection. Background technique [0002] For broadband satellite communication systems, due to the high transmission rate and large transmission delay, the system must have corresponding congestion management functions to ensure the reliable and stable operation of the network and the QoS requirements of user services. Although in terms of overall requirements, the congestion management function of the broadband satellite communication system based on on-board switching is the same as that of the ground system, but due to the influence of factors such as the spaceborne environment and transmission delay, effective congestion management in the ground system The measures are not suitable for broad...
