Embodiment

[0028] The technical solution of the present invention will be described in detail with examples below.

[0029] The bandwidth allocation method of the VSAT satellite communication system based on the star network in this example is applied to the VSAT satellite communication system based on the star network.

[0030] Firstly, each end station uses a log to record its own packet arrival time, packet size, packet source IP, packet destination IP, packet source MAC, packet destination MAC, time difference between adjacent packets, preset The number of packets arriving in cycle 1, the terminal access information of the user network side interface, the terminal departure information of the user network side interface, and the air interface traffic; the network controller of the master station establishes a timing prediction machine learning algorithm.

[0031] Then the network controller of the master station collects the packet arrival time, packet size, packet source IP, packet ...

Abstract

The invention relates to the technical field of satellite communication, and solves the problems of low utilization rate of channel resources and many fragments generated in resource allocation in the existing star network-based VSAT satellite communication system. The technical solution is summarized as follows: the end station collects traffic information, the master station uses the flow information as a sample to establish a flow time series prediction model of the end station and sends the model to the end station, the end station predicts future traffic according to the model, and then calculates the required bandwidth, the end station The station calculates the requested bandwidth value according to the required bandwidth and the remaining bandwidth percentage of the current channel of the master station and applies for bandwidth resources to the master station, and the master station allocates bandwidth. The beneficial effect is: the present invention improves the channel resource utilization rate and reduces channel resource allocation fragments. The invention is especially suitable for VSAT satellite communication system of star network.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to the technical field of bandwidth allocation of a VSAT satellite communication system based on a star network. Background technique [0002] In the current VSAT (Very Small Aperture Terminal) satellite communication system based on star network, the minimum bandwidth and maximum bandwidth of the VSAT terminal station are mainly set as the bandwidth range of the terminal station. The network controller applies for or releases the bandwidth. The disadvantage of this method is: if the current network is idle, there is a large amount of bandwidth left, and the end station is still limited to the maximum bandwidth, resulting in the end station being unable to obtain more bandwidth, and the utilization rate of channel resources is low. In this way, the bandwidth adjustment of the terminal station is based on the QOS queue, and the uneven adjustment of the QOS queue will ...
