Abstract

The invention relates to a method for suppressing the route congestion in a satellite network. The method comprises the following steps: calculating an algebraic value of each path for each of a plurality of tasks; Determining a path of minimum first M generation value and adding the path to the path pool; A multipath-based congestion control algorithm for LEO satellite networks is proposed to allocate the bandwidth of all paths in the path pool to determine the traffic bandwidth ratio for each path of each task. And allocating bandwidth for each path of each task according to the traffic bandwidth ratio. The invention can minimize the bandwidth variance of the network transmission link and the network overhead, thereby maximally suppressing the routing congestion in the satellite network,thereby achieving the optimal utilization of the network resources.

Description

technical field [0001] The present invention generally relates to the field of satellite network communication, and in particular relates to a method for suppressing routing congestion in a satellite network. Background technique [0002] The low-orbit satellite communication network has broad development prospects due to its advantages such as global coverage, low transmission delay, low power consumption links and strong invulnerability, and is an important part of the future mobile communication system. In addition, with the development of communication technology, a new generation of low-orbit satellite communication network characterized by inter-satellite links and on-board processing technology is constantly developing. The use of low-orbit communication satellite networks to provide mobile data access services for aviation and navigation has already become a trend. [0003] The network topology of low-orbit satellites is generally a mesh (MESH) structure, and each s...
