Problems solved by technology

[0014] Through the comparison of the above three simulation platforms, it can be found that the various satellite network simulation platforms currently appearing are all single-machine centralized control, with heavy loads, and cannot flexibly expand functions, and do not use actual channels to control satellite networks. The communication link is simulated

Embodiment Construction

[0057] 1. Architecture

[0058] The satellite network simulation platform construction method based on the open source firewall and mobile agent technology is a simulation platform construction technology for simulating the operation status of the satellite network. The platform uses the Netfilter framework of the Linux platform to design an access control module to control the communication links between satellites, simulating the characteristics of high delay and easy on-off of the actual communication links between satellites in the satellite network. The logical structure of the satellite network operation simulation platform mainly includes satellite simulation entity, access control module, satellite network operation data system, and platform control center.
