The sequence of preferred path to satellite node to the purpose satellite node of broadcast obtains the second ranking results.For example, it is assumed that first
Congestion occurs for a satellite node in sub-network, the congestion situation of congestion is then occurred while to the first sub-network and the
Two sub-networks broadcast, after another satellite node receives congestion situation, first based in part on congestion feelings in the first sub-network
Sequence of the condition adjustment from another satellite node to the preferred path of corresponding purpose satellite node obtains the first sequence as a result, so
Another satellite node is another from this based in part on congestion situation and the adjustment of the first ranking results in the second sub-network afterwards
The sequence of preferred path of one satellite node to corresponding purpose satellite node obtains the second ranking results.Based in part on
The sequence of congestion situation adjustment preferred path is because same satellite of same period may will receive two or more congestion situation.
Preferably, it is noted that the adjustment of ranking results does not represent actual path and necessarily changes, because of some distances
The optimal path that the farther away satellite node of satellite node of congestion occurs may not need the satellite section via the generation congestion

Upper reciprocal inverse toroidal link, when preceding first virtual opetrating system of into endless chain road 110 or second is empty
Quasi- operating system 120 needs data being sent to another preceding into annular link first virtually to annular link by preceding
When operating system 110 or the second virtual opetrating system 120 but the preceding generation congestion to annular link, one first virtual behaviour
Make system 110 preferentially to attempt to route data to another the first void by inverse toroidal link corresponding with forward direction annular link
Quasi- operating system 110 only just attempts the side of the sub-network of switching transmission data when inverse toroidal link still remains congestion
Formula transmits the data.The present invention at least can be realized following advantageous effects using this mode: in the prior art, if
One link is obstructed, then can attempt another link different from the link to transmit data, and during this, it is directed not only to
To the computing cost problem of path planning, and if numerous satellites all attempt another completely immediately if a link is obstructed
In the case where different links, then it is easy to cause network congestion, and passage the case where this congestion at any time can become apparent from, and lead
Satellite communication network efficiency of transmission is caused to reduce, and after the present invention constructs annular link, the reciprocal communication direction of both direction
Reachable purpose satellite node, when congestion or partial fault occurring in one direction, it is preferential attempt by reverse link communication into
