Abstract

The route fast convergence optimization method of the LEO / MEO satellite network includes: a step of dynamic two-way forwarding detection; a step of coverage clustering for the MEO / LEO satellite network; and a step of judging the fault type of the satellite network. In the fault detection stage, the fault detection speed is improved through dynamic bidirectional forwarding detection; in the LSA diffusion stage, the routing overhead and queuing delay are reduced through the overlay network clustering algorithm; in the routing table update stage, the SFTJM algorithm is used to reduce the routing table update time Delay, and finally achieve the rapid convergence of the entire network.

Description

technical field

[0001] The invention belongs to the field of satellite network dynamic routing protocol, in particular to a fast convergence optimization method for LEO / MEO satellite network routing. Background technique

[0002] With the development of network communication, satellite network, as the extension of ground network, has attracted more and more attention of scholars. Due to the characteristics of large delay and high dynamics of the satellite network, the original routing protocol on the ground cannot adapt to the satellite network. At present, scientists at home and abroad propose to combine the virtual topology routing algorithm with the OSPF protocol and the dynamic routing protocol to improve the routing convergence speed of the satellite network. . The RLSR protocol is a representative of this type of protocol, but the protocol still has the following deficiencies:

[0003] First, in the fault detection phase of the RLSR protocol, in order to achieve fast...
