Embodiment Construction

[0045] The basic idea of ​​the present invention is to propose an on-board IP switching label applied to a multi-beam GEO broadband multimedia satellite communication system and a distribution method thereof, namely an on-board IP switching label and a distribution method of the multimedia satellite communication system. The onboard IP switching label consists of an ingress label field, an egress label field, and a label check field. The method for distributing labels for on-board IP switching includes a forwarding equivalence class differentiation stage, a forwarding label information table generation stage, and a label distribution stage. The invention can adapt to the improvement of the capacity of the multi-beam GEO broadband multimedia satellite communication system and the increase of the number of users, and can reduce the occupancy rate of the space communication resources by the control information in the multi-beam GEO broadband multimedia satellite communication. In...
