Abstract
One of the characteristics of satellite switching network is limited link resources. When the satellite switching network is congested, there are not enough resources to send the congestion notification message to the ground terminal. In order to solve this problem, a novel algorithm of congestion control based on satellite switching is proposed in this paper. The congestion notification messages are sent while transmitting the switching data according to the specific hiding approach, which uses the redundant information in the switching data to embed the congestion control information into the transmission data. The method can send congestion control messages to the ground terminal without any additional physical resources, and also increase the amount of information that can be transmitted by each port of the onboard switch. The performance analysis and simulation result show that the proposed algorithm can not only avoid congestion in the onboard switch, but also save link resources and improve the performance of the satellite switching network.
