Abstract

The present invention provides a low-orbit satellite network traffic optimization method and device, which relate to the technical field of satellite communication, including: an acquisition step, using the deterministic strategy network of the target low-orbit satellite to collect current environment observation data, and determine the deterministic strategy Reward of the network; determination step, based on the current environment observation data, determine the execution action of the target low-orbit satellite, and obtain the target environment observation data collected by the target low-orbit satellite after executing the execution action; construction step, use the current environment observation data , execution actions, target environment observation data and rewards from the deterministic policy network to build a database; the optimization step uses the Q network of the ground station to call the target data in the database, so that the Q network of the ground station uses the target data for training, and utilizes The traffic optimization strategy generated by the trained Q network solves the technical problems of weak optimization ability and poor applicability in the existing low-orbit satellite network traffic optimization methods.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a method and device for optimizing flow of a low-orbit satellite network. Background technique [0002] In the prior art, the network traffic of low-orbit satellites is generally optimized through the following two methods. [0003] Elastic Load Balance (ELB) is a traffic distribution control service that distributes access traffic to multiple back-end elastic cloud servers according to the forwarding policy. It can expand the external service capability of the application system through traffic distribution and improve the fault tolerance of the application. . An Elastic Load Balancer accepts incoming traffic from clients and forwards requests to backend servers in one or more Availability Zones. [0004] HGL (hybrid global-local load balancing routing): The HGL algorithm believes that the traffic of the satellite network is divided into predictable large-scale...
