Efficient parallel simulation method and system for super-large-scale low earth orbit satellite network

Abstract

The invention discloses an efficient parallel simulation method and system for a super-large-scale low-earth-orbit satellite network, and aims to simulate dynamic characteristics of the low-earth-orbit satellite network while performing efficient parallel simulation. According to the method, topology partitioning, topology construction and parallel simulation of a simulation process can be automatically carried out in a computing cluster with a plurality of CPUs (Central Processing Unit); meanwhile, a satellite network topology division mechanism provided by the invention can quickly divide the network topology into a plurality of simulation processes, thereby reducing the synchronization overhead between the processes and improving the parallel simulation efficiency; and a conservative synchronization mechanism oriented to a satellite dynamic network is provided, so that the topological consistency among a plurality of simulation processes can be ensured, the causality is ensured, and the correct operation of parallel simulation is promoted.
