Problems solved by technology
[0005] The purpose of the present invention is to address the deficiencies in the above-mentioned prior art, and provide a low-orbit satellite network routing method using a relationship matrix and link monitoring, which is used to solve the problem of signaling information of the local controller due to inter-satellite link failures. The problem of inability to send and receive, and the problem of invalidation of preset routes caused by changes in the scale of the satellite network
It can be seen that the present invention calculates the routing table by the satellite instead of the ground SDN controller and presets the routing table on the satellite. When the scale of the satellite network changes, the ground SDN controller resends the Unicom relationship matrix, and according to China Unicom's relationship matrix recalculates the routing table, which solves the problem of failure of preset routes caused by changes in the size of the satellite network

The invention discloses a low earth orbit satellite network routing method using a relation matrix and link monitoring, and solves the problem that signaling information of a local controller cannot be transmitted and received due to inter-satellite link faults in the prior art and the problem that a preset routing table fails due to the scale change of a satellite network. The method comprises the following implementation steps: 1, constructing a low-orbit LEO satellite network; 2, generating a communication relation matrix; 3, sending the communication relation matrix; 4, monitoring an inter-satellite link state; 5, flooding fault inter-satellite link information to the whole network; and 6, generating a low earth orbit satellite network routing table. The low-earth-orbit satellite network routing table generated by the method can better adapt to the change of the satellite network scale, and can fully meet the reliability requirement of the low-earth-orbit satellite network routing.
