Abstract

The invention discloses a broadband satellite communication system and a communication method based on satellite-borne IP exchange, including a broadband communication satellite with a satellite-borne IP exchange function, a system network management and control center, a gateway station and a satellite terminal; The broadband communication satellite with IP switching function performs IP switching on the star; the system network management control center cooperates with the gateway station and the satellite terminal to realize the maintenance and distribution of routing switching information based on the satellite-borne IP switching broadband satellite communication system; the satellite terminal According to the switching label information assigned by the system network management and control center, the gateway station will package and unpack the received service data packets to realize the sending and receiving of services. The system performs IP exchange on the satellite without implementing complex routing algorithms. The system construction and expansion are simple and flexible. While improving the utilization efficiency of satellite system link resources, it has good realizability. Simultaneously, the invention also discloses a communication method of the star-borne IP switching broadband satellite communication system.

Description

technical field [0001] The invention belongs to the technical field of broadband satellite communication systems, and relates to a satellite-borne IP switching broadband satellite communication system and a communication method. Background technique [0002] Broadband satellite communication system is a kind of satellite communication.
