It is characterized in that the simulation system combines SDN and virtual network slicing technology. The simulation system includes application layer, slice layer, control layer and data layer from top to bottom; The virtual network resources are encapsulated into business slices to complete the mapping from the physical network to the simulated network. The control layer modularizes and encapsulates multiple functional modules, and provides a simulation system control interface. As the basic resource facility of the entire architecture, the data layer is composed of software-defined switches and simulation nodes, carrying network data streams.

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 ...
