Embodiment Construction

[0045] The basic idea of ​​the present invention is to propose an on-board IP exchange label and its distribution method applied to a multi-beam GEO broadband multimedia satellite communication system, that is, an on-board IP exchange label and its distribution method for a multimedia satellite communication system. The on-board IP switching label consists of an ingress label field, an egress label field and a label verification field. The label distribution method for on-board IP switching includes the stage of forwarding equivalence class distinction, the stage of generating a forwarding label information table and the stage of label distribution. 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 space communication resources by control information in the multi-beam GEO broadband multimedia satellite communication. I...
