Description

technical field [0001] The invention designs a service-driven large-scale network simulation method and system, belonging to the field of communication network simulation. Background technique [0002] Large-scale communication networks have complex network structures, large coverage areas, and multi-source heterogeneous networks, such as: space information networks, self-organizing networks, UAV cluster networks, and multi-level cross-domain networks. Their requirements for scalability and compatibility higher. In some network scenarios, the communication nodes of each plane have different motion models and are in a high-speed motion state, and the relative positions of the nodes are constantly changing. These characteristics make it difficult to simulate and analyze large-scale networks, and most network simulation software is based on discrete event simulation. There is no real data flow exchange in node communication during the work process, and there is a gap with the ...
