Flexible forwarding system combining frequency resource optimization and link dynamic management technology and forwarding method thereof

Abstract

The invention discloses a flexible forwarding system combining frequency resource optimization and a link dynamic management technology and a forwarding method thereof. The flexible forwarding system comprises a frequency resource optimization module, a satellite-borne switching controller, a route switching controller, a digital channelizer, a frequency resource optimization module and a link dynamic analysis module, and the frequency resource optimization module is connected with the satellite-borne switching controller. The satellite-borne switching controller is respectively connected with the route switching controller and the link dynamic analysis module, and the route switching controller is respectively connected with the plurality of digital channelizers. The method solves the problem that a satellite flexible transponder cannot autonomously perform frequency resource optimization and link dynamic analysis and cannot autonomously complete route switching matrix updating in the transponder.

Description

technical field [0001] The technical field to which the present invention belongs; in particular, it relates to a flexible forwarding system and a forwarding method combining frequency resource optimization and link dynamic management technologies. Background technique [0002] After years of development, the communication satellite system has developed into a new mode that supports multiple bands, various types of services, and multi-satellite multi-band collaborative work. At present, in multi-beam communication satellites, transponders mainly use transparent and regenerative transponders, as well as flexible transponders combining the above two methods. [0003] The data exchange policy of the transparent transponder is fixed in advance, and there is no way to change it accordingly when the data rate changes. The regenerative transponder has a serious dependence on the encoding method and protocol of the physical layer, and the transponder is no longer applicable when th...
