Problems solved by technology

[0005] However, in this transmission rate adjustment scheme, there is often a large gap between the adjusted transmission rate of the interface and the ideal transmission rate of the air interface (such as figure 1 shown), which will waste more bandwidth resources on the satellite-ground link

Abstract

The application provides a transmission rate adjustment method and device, the method is applied to ground routers, the method includes: receiving the LLDP message sent by the satellite antenna; the ideal transmission rate curve of the satellite obtained according to the satellite elevation angle information and the satellite identification information Figure, determine the longest access time for the satellite antenna to access the satellite, and start a timer for it; send data packets to the satellite antenna according to the maximum transmission rate; if the PAUSE frame sent by the satellite antenna is received, determine whether the timer is overdue ; When the judgment result is yes, determine the second PAUSE time according to the first PAUSE time, and after waiting for the second PAUSE time, perform the step of sending data packets to the satellite antenna according to the maximum transmission rate until the ground router monitors that it is connected to the satellite antenna. When an interface down event occurs on the interface connected to the satellite antenna, stop sending data packets to the satellite antenna. This application can save the bandwidth resources of the satellite-ground link.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for adjusting a sending rate. Background technique [0002] In the process of satellite-ground interconnection, because the satellite has its own independent orbital plane, its position relative to the ground router (also called the ground receiving station) is dynamically changing, and the satellite antenna (also called the satellite ground receiving station) The connected satellites are also dynamically switched. Therefore, the satellite-ground link will actually be affected by the elevation angle of the satellite antenna (actually the position of the satellite), and the transmission rate of the air interface involved in the satellite-ground link will be as follows: figure 1 The linear change shown. [0003] When the satellite antenna is connected to a certain satellite, the ideal transmission rate of the air interface on the satellit...
